Common Toyota Tacoma Transmission Problems & Their Fixes

The Toyota Tacoma is one of the most popular trucks models and with good reasons. Not only is it reliable when it comes to engine performance, fuel consumption, and longevity. It is also one of the least likely to require constant repairs as compared to other trucks. Not to mention is incredible towing capacity.

However, even this powerhouse is bound to breakdown from time to time. Keep reading to learn how to troubleshoot and fix common transmission issues you may experience.

What are the worst Toyota Tacoma years to avoid

The model years of the Tacoma to avoid are:

2006-2009

The 2006-2008 models all have issues with paint chipping and peeling. This might not be too big a deal to you, but they also have problems with transmission and engine failures.

The 2006 model year can be especially problematic. These Toyota Tacoma models have a frame that tends to rust or break at the 100,000-mile mark, which could cost more than $3,500 to repair.

The 2007 model year doesn’t fare much better than the 2006 version. Tacoma trucks from 2007 tend to have sticky accelerators, which can cause severe problems for drivers.

This Toyota truck’s 2008-2009 models have had early problems including sudden unanticipated acceleration and a slipping clutch.

2011-2012

The 2011 version of the Tacoma suffered from headlight issues, including flickering and cracked covers. Many owners of the 2011 model also reported a repetitive clicking sound coming from the truck.

The 2012 versions come with several engine defects and heavy vibrations occurring while driving. The problems appear around 30,000 miles. You might be out of the woods when looking at a used Toyota for sale with more than 30,000 miles from these two model years, but you might not want to take that chance.

2016-2017

Both of these model years have reported dozens of transmission flaws, and the 2016 version has a faulty engine.

Best Toyota Tacoma years to go for

The most reliable year models of Tacoma:

1995 Toyota Tacoma
1996 Toyota Tacoma
1997 Toyota Tacoma
1998 Toyota Tacoma
1999 Toyota Tacoma
2000 Toyota Tacoma
2001 Toyota Tacoma
2002 Toyota Tacoma
2003 Toyota Tacoma
2004 Toyota Tacoma
2005 Toyota Tacoma
2010 Toyota Tacoma
2013 Toyota Tacoma
2014 Toyota Tacoma
2015 Toyota Tacoma
2018 Toyota Tacoma
2019 Toyota Tacoma
2020 Toyota Tacoma

Toyota Tacomas from 1995 to 2004 are highly reliable with very few reported complaints. A majority of the reported issues are minor defects and don’t become a problem until after 100,000 miles on average. There’s a slight chance that a flaw could appear in the first 50,000 miles of the truck’s life, but if so, it will only cost around $500 to fix.

The 2014, 2018, and 2019 Tacoma year models are still a safe bet but less reliable than the early models. Each of these has similar numbers of defects to those, but these defects appear much earlier.

Issues like premature seat wear or a broken A/C unit have been reported under 40,000 miles, and the 2018 and 2019 models both have early problems with vibration. These should be easily fixable, but they’re something to be aware of. The 2013 Toyota Tacoma has similar vibration and drivetrain problems but more complaints, so it isn’t quite sturdy.

The 2005 model has a decent number of complaints, but most have to do with paint chipping and peeling after 80,000 miles, so there isn’t much to worry about here. With the 2010 and 2015 models, there is a slight chance you might have some early engine or brakes problems, like squeaking or worn pressure plates, but the chances are low enough that it shouldn’t be an issue.

These year models would be advisable to purchase, but the 2020 would be the safest overall because it has zero complaints.

You can only get a four-wheel drive double cab with the 3.5L V6, but you do have the option between a six-speed automatic or manual! Payload capacity is the lowest at 1,135 pounds, and so is the tongue load and towing capacity at 640 and 6,400 pounds respectively.

How to take good care of your Toyota Tacoma to avoid common problems

Following basic car maintenance tips may help keep your car running. But that’s not all. There are many rewarding advantages to proper car maintenance that don’t have to do with getting from point A to point B. Keeping your car maintained will help your vehicle last longer. It can even help you snag a higher resale price if you decide to sell.

Something as simple as checking tire pressure or washing your car can add value to your vehicle. Yes, it’s that simple! From better fuel efficiency to retaining resale value, these simple car maintenance tips can help improve your vehicle-owning experience.

In addition, if you drive a new Toyota, you can take advantage of Toyota Care. Every purchased and leased new Toyota comes with the Toyota Care scheduled maintenance plan and roadside assistance.

Don’t Skip Scheduled Car Maintenance Services

Check your vehicle’s owner’s manual and find out when your recommended car maintenance services should be scheduled. Usually, basic car maintenance involves checking or replacing parts like spark plugs, wires, fluids, and serpentine belts. Scheduling maintenance services through your dealer may be best. There are at least three good reasons for this:

The first reason: genuine parts and expert customer care. Your Toyota dealer will have the knowledge and parts to keep your car running well. Dealers often put a sticker on your vehicle that includes a reminder of the date of your next maintenance service. Yet, some locations will take it a step further with reminder emails about your appointment. That way, you can schedule a time that works for you and better remember the date and time of your appointment.

The second reason has to do with history. Going to the same Toyota dealer for maintenance means you’ll have a complete service history for the vehicle. Potential buyers may consider this an added bonus when considering your vehicle for purchase.

The third has to do with price. A well-maintained car with up-to-date records attracts a better resale price. If you do decide to sell, you could get a much better payout.

Read Your Owner’s Manual

Your owner’s manual will tell you when your recommended services should happen. It contains a great deal of other helpful information, as well.

Your owner’s manual will give you insight on the correct oil and gas to use, how to diagnose problems, and how to use your vehicle’s infotainment system. It will help you to get started and will give you a good base of knowledge about the features and requirements of your specific vehicle. Each vehicle is different, so the best way to understand your vehicle’s needs is to read your vehicle’s owner’s manual.

Change the Oil Regularly

If your car uses conventional motor oil, it likely should be changed every 3,000 miles or 3 months. If your car has synthetic oil, it likely should be changed every 5,000-10,000 miles or 6-12 months.

As we move further away from the days of conventional motor oils, most newer vehicles no longer have to have an oil and filter change every 3,000 miles. High-efficiency engines and high-quality oil have changed the way we approach this service. Some vehicles don’t have to get an oil change more than once every 7,000 – 10,000 miles. Due to how efficient engines and motor oils have become, commonly-held advice may not be correct anymore.

Getting an oil change is a simple way to keep your vehicle in good running condition. Without clean oil to efficiently lubricate your engine’s moving parts, serious damage can occur. In fact, not maintaining the oil can void your warranty and even cause engine failure. If that happens, you’ll be spending thousands of dollars to fix the problem.

When you need to change your car’s, oil depends on the type of oil you use. If your car uses conventional motor oil, it likely should be changed every 3,000 miles or 3 months. If your car has synthetic oil, it likely should be changed every 5,000-10,000 miles or 6-12 months. See your owner’s manual or contact your dealer if you are unsure of which type of oil is recommended for your specific vehicle.

Use the Correct Octane Rating

Higher is not always better when it comes to gasoline. You might be tempted to use a higher-octane fuel to get more power. If sports cars perform better with higher octane fuel, what about your car?

There’s a reason sports cars require higher octane fuel. They’re designed to use it. The engine itself is often electronically tuned to account for a particular octane level when delivering fuel to the engine cylinder. Using a higher-octane fuel than your car was tuned for can result in lower engine efficiency instead of improving performance. Be sure to look in your manual for the fuel rating your car needs.

Inspect your car

Take a few moments to look at your car each day. There are a few reasons to do this, but the main reason has to do with vehicle health. Regularly reviewing your car clues you into things that need tending to such as transmission fluid change or refill, tire pressure, cracks in the windshield, and chipped paint.

Learn Your Vehicle’s Warning Lights

No one likes seeing a warning light turn on. It could turn a simple spin around town into a stressful drive home. That’s why you should learn what each warning light means and what to do when one is on.

Often, having a warning light on is not a serious thing. It could mean you’re low on gas or that your car is due for a scheduled service. Other times it could mean you have low oil pressure or your coolant system isn’t keeping the engine cool enough to run. If one of these warnings come up, your car needs service as soon as possible. Your owner’s manual should let you know what each light means and how to address them. Your Toyota Dealer can always answer questions about warning lights as well.

Get Your Car’s Fluids Checked

Like tires and lights, it’s a good idea to check your vehicle’s fluid levels. Even if you leave changing them up to the pros, you should still know how to check them.

A good way to learn about your vehicle’s fluids is to review your owner’s manual. If you need help with checking the fluids, you can ask your dealer’s Toyota mechanic for tips.

In general, you can keep your car in top shape by making sure these fluids are full and fresh:

Radiator Coolant/Anti-freeze Fluid
Transmission Fluid
Power Steering Fluid
Air Conditioning Coolant
Brake Fluid
Washer Fluid
Motor Oil

Educate yourself about the serpentine and timing belts

The serpentine belt is one of the most important parts of your car and one that flies under the radar. Usually made of rubber, these belts are used to drive and assist timing of many important car parts, like the AC condenser, water pump, power steering, and alternator. If damaged, your engine could overheat and stop. The serpentine belt is vital to your vehicle’s performance and needs care.

A timing belt or chain, on the other hand, can be found inside your engine. It drives the camshaft when there aren’t any gears driving it directly. Basically, the timing belt controls when the engine valves open and allows fuel and air into the cylinder. It can also drive the oil or water pump depending on engine type.

These belts feature teeth on the inside and are usually made of more sturdy materials such as neoprene, metals, but can also be made of rubber. Interference engines that use rubber timing belts rely on the integrity of the belt to run properly. If the belt were to break while driving, catastrophic engine damage can occur. Vehicles that use timing chains rather than rubber timing belts may never need a replacement.

Ask your Toyota service professionals about timing and serpentine belts, as well as your vehicle’s engine during your scheduled service.

Check Your Car Battery

While most modern batteries don’t need much tending to, it’s good to know how to check them and where they are. This is especially true if you suspect there’s an issue with your battery.

The best time to check it is when you check your vehicle fluids. Just take a quick look at your car battery while the hood is popped. Make sure there isn’t any corrosion and/or build-up on the battery’s contacts. If there is, don’t worry. All you need to do is clean the contacts with a battery cleaning brush. Your Toyota Service Center can handle this maintenance for you. However, if you’re a do-it-yourself kind of person, you can buy one at any auto parts store.

If you have corroded car battery terminals, don’t worry. Just follow these steps to get them looking new again:

Make sure your car is turned off.
Loosen the nut of the negative clamp and unfasten the cable from the battery.
Do the same for the positive clamp.
Ensure both positive and negative clamps are fastened without touching each other or any connected conductive surfaces.
Mix one tablespoon of baking soda with one cup of hot water.
Use a battery cleaning brush to mix the ingredients and scrub it on the top of the battery.
Clean the clamps and posts with the mixture and rinse with cool water.
Once it is dry, lubricate using petroleum jelly or dielectric grease on all exposed metal on the battery terminals and prepare to put it back together.
Reattach the positive cable to the positive terminal and then reattach the negative cable to the negative terminal.
Make sure you wear gloves and try not to touch any part of the corrosion. If there are any cracks on the battery or it’s leaking fluid (acid), get it replaced.

Replace the Engine Air Filter

Think of the engine air filter as your car’s lungs. Your car “breathes” better with clean filters. According to FuelEconomy.gov, the official U.S. government source for fuel information, replacing filters improves acceleration and fuel economy.

Your vehicle’s engine works best on a mixture of air and fuel. Any debris or other contaminants that get sucked into your engine along with air can damage its ability to run well. That’s why it’s important to replace a dirty or dusty filter for a cleaner engine.

Refer to your owner’s manual or stop by your local Toyota dealer to see if your air filter needs changing. If you have been in an area with a lot of dirt and dust, check your air filter. You may need to replace the air filter sooner than you think.

Check Spark Plugs and Brake Pads

Clean and working spark plugs are essential to a smooth-running engine. However, as with the battery, your spark plugs can get covered in build-up. Dirtier spark plugs mean the engine has to work harder to get a spark. You may have to clean or replace the spark plugs throughout the life of your car. Luckily, spark plugs are one of the easiest and cheapest engine parts to replace. Check your owner’s manual for when it’s best to replace them. In general, you should check about once every year. For assistance with this task, you can ask your dealer’s Toyota mechanic to check them for you.

Keep your car running safely as well by checking your brake pads. While your vehicle may have built-in sensors to alert you if the brake pads need attention, you should listen for signs of problems just in case. If the brake pads need replacing, you might hear squeaking or even metal grinding. Any noises you hear from your brakes could be worth checking on. Brake linings wear gradually, so you might not notice if they are not working great until something goes wrong. Being proactive about brake maintenance can prevent you from having to replace more expensive parts like rotors.

Toyota Tacoma transmission rattling noise when accelerating

Below are possible causes and how to fix them;

Broken Heat Shield

Heat shields are metal guards that surround various parts of the exhaust system, keeping your car safe from the heat it puts out.

One reason heat shields tend to break is due to their close to the ground location. Often around the gas tank, muffler, exhaust piping, and exhaust manifold. This not only leaves them exposed to debris but moisture as well, which means they will likely develop problems with rust.

If the damage is severe, it can cause your car to make a rattling sound when accelerating.

The reason they do so while accelerating is due to more strain being put on the engine. The harder it works, the more air that flows through the exhaust, which is where the bulk of the heat shields in your car are.

How To Fix

The good news is that unless they have sustained real damage, heat shields are quick and affordable to repair. If you do have to replace one, you’ll likely spend between $250-$300. Otherwise, having it spot welded at a local shop should do the trick.

Damaged Engine Mounts

If you didn’t already know, the average car engine weighs about 300 lbs. – and the engine mounts are what hold it securely in place. They’re made of rubber and metal, so as you may have guessed, if they’re broken, there’s nothing to stop it from moving around.

This means metal on metal contact, which can cause your car to make a rattling noise while accelerating due to the added workload (as well as momentum).

If left alone, there will likely be more than just a rattle to worry about. Some possibilities include a bent or broken exhaust manifold, a decrease in handling, or drivetrain failure.

How To Fix

The good news is that broken or damaged engine mounts are not difficult to resolve. While you can always crawl under your car and check yourself, it might be easier to have a licensed professional put it on a lift and take a look.

They should be able to replace the worn/broken mount for between $200-$500.

Valve Train Issues

If your car makes a rattling noise that sounds like glass bottles clinking together, it’s likely a valve train issue.

This system is in charge of the operation of the intake and exhaust valves. If any of these are stuck or worn (including the hydraulic lifters), it can cause premature ignition inside the combustion chambers.

This is often referred to as carbon rap, and it’s usually caused by dirty oil or filling your car with gas that is not the correct octane level.

How To Fix

If it is the valve train (which is located on the top of the engine), the first thing you should do is check what shape your oil is in. If it’s dirty, an oil change may be all that’s needed.

It may also be that your engine requires a higher-octane fuel, which will show in your owner manual. If it’s designed for 95 and you’re putting in 89, engine performance will suffer and possibly create a rattling sound.

Transmission Problems

A lot goes on inside a transmission, and as with most engine components, if it’s not receiving enough lubrication, it won’t be able to operate correctly.

Transmission fluid forms a thin layer between the moving parts so that they don’t rub directly against each other. Without enough of it, they will, which can cause your car to rattle while accelerating.

Ignoring a transmission that’s low on fluid will eventually lead to a costly repair bill. As metal grinds on metal, it will cause the gears to wear down, and when they become unusable, you’ll have rebuild or replace the transmission.

How To Fix

Thankfully, if you routinely change your transmission fluid every 30,000-60,000 miles, you should never have an issue with it. Regardless, if it is your tranny, the first thing you should do is check the fluid levels. If it’s low, then you will need to add more.

For more information on tranny fluid, as well as the costs associated with having it replaced, check out our previous article here.

Worn Exhaust Components

There are a lot of different components inside an exhaust system that can cause your car to rattle when accelerating.

Some of these include:

Loose or broken pipe connection
Rusty muffler
Blown exhaust gasket
Broke or disconnected exhaust hanger
Catalytic converter failure
Faulty active exhaust

Ignoring any of these can have adverse effects on the rest of the system. Not only that, but they can also cause a decrease in performance and fuel economy.

How To Fix

The first step is to figure out which part of the system is having an issue. You can crawl under your vehicle and inspect it for damage, just be sure to let it cool down first if you’ve recently been driving.

You can also use your hands to “shake” the system, listening for any rattling noises.

If you don’t feel comfortable doing this yourself, taking your car to a licensed mechanic may be your best bet. If they don’t notice any visible issues, they can also perform a pressure test to tell if there’s a leak somewhere.

Toyota Tacoma manual transmission rocks when I let off brakes

If your car jerks when accelerating, it can be an indication of several current or potential problems. Here we’ll go over the most common culprits and how to fix the issue.

When car feels like it’s jerking, surging, bucking, or stuttering after you step on the gas pedal, it’s usually a result of inadequate fuel, air, or spark during the combustion process.

However, there are other things that can be the cause. You want to find and fix the problem as soon as possible before it gets worse and costlier to fix.

Dirty Fuel Injectors

This is a common and annoying problem that can be responsible for a variety of issues. Dirty injectors can cause your car to lose power and make your car jerk while driving at constant speed or from a stop due to frequent engine misfires. You can also hear as the engine stutters from inconsistent fuel intake.

Cleaning the injectors should be done regularly to avoid this problem. Thankfully, this process is quite easy using a fuel injector or fuel system cleaner.

However, the injectors can be so fouled up with carbon deposits that even the best fuel injector cleaner may not do the trick. In those cases, you’ll have to either have to take the injectors out to attempt to manually clean or simply replace them.

Blocked Catalytic Converter

A catalytic converter is responsible for reducing the number of pollutants that exit out of a car’s exhaust. When the air/fuel mixture in your engine is too rich, a blockage can develop in the catalytic converter over time which disrupts the airflow of the exhaust system.

This can result in stuttering, jerking, and an overall delay in responsiveness whenever you step on the gas. Besides the jerking, other symptoms may include a rotten egg odor (hydrogen sulphide), a drop in the car’s fuel efficiency, and the check engine light may come on.

You may be able to unclog minor blockages by first using a good catalytic converter cleaner. If that doesn’t work, you’ll need to take it to an auto repair shop to fix the problem which will likely include replacement of the catalytic converter.

Faulty Mass Airflow Sensor

If you notice your car surging forward or jerking at high speeds, it may be due to a mass airflow sensor (MAF) that is failing. Its job is to measure the amount of air entering the engine so it can relay this info to the car’s computer.

The computer then instructs the fuel injectors to provide the right amount of fuel at the right time for proper air/fuel mixture.

With a faulty MAF sensor, you may experience your car unexpectedly jerking or surging forward while driving at higher speeds such as on the highway where it would be most noticeable.

A check engine light should be present when the mass airflow sensor is bad but you can easily confirm via an OBD2 scanner.

Bad Fuel Pump or Filter

The cause of your car jerking while accelerating is often a fuel supply issue. When the correct amount of fuel is not being delivered to the engine, it’s often best to start at the beginning.

In this case it would be the car’s fuel pump. A failing fuel pump would struggle to keep up with fuel demands and cause your car to jerk or surge forward while driving.

Alternatively, you may have a clogged fuel filter that’s restricting the flow of fuel which also can cause issues as fuel delivery is inconsistent. Replacing the fuel filter is a fairly simple and inexpensive process.

Dirty Air Filter

As you read this article, you’ll notice an improper air/fuel mixture is often the culprit if your car jerks or sputters when accelerating. Opposite the fuel side of things, is proper air intake.

When not enough air makes it into the combustion chamber, you’ll often get the same issues when not enough fuel.

Your car’s air filter is the first line of defense against dirt and other foreign particles. A dirty air filter will allow some particles to get into the engine, which in turn will affect performance and cause jerking.

Check the condition of your air filter. If it’s dirty, replace it. It should only cost $10-$20 and take a few minutes to replace. Alternatively, you can purchase a reusable air filter such as a K&N which allows for future cleanings instead of replacement.

A clean filter can drastically improve the lifespan of your car’s engine, including reducing or eliminating the acceleration jerks.

Faulty Spark Plugs

One of the most common causes is also one of the easiest to identify and fix. During the combustion process, a good spark is needed to properly ignite the fuel in each cylinder.

A bad or dirty spark plug can prevent this proper ignition and will cause the engine to misfire. While driving, it feels like your vehicle jerks or shutter when accelerating.

Fixing this problem is as easy as replacing the bad plug. If you don’t remember the last time you replaced your spark plugs, it may be a good idea to get them all changed out. This is a quick and inexpensive repair.

Moisture Buildup

On colder days, condensation can form under the distributor cap. This mainly occurs when you have the car parked outside overnight. This moisture will cause the engine to misfire; thus your car will jerk when accelerating at low speeds.

Luckily, the problem will go away once the water is gone, but repeated moisture buildup can tax your engine over time.

You can avoid this issue altogether by ensuring your car’s parked in a garage or other protected location. A thermal cover can also help reduce the risk of condensation when shelter isn’t an option and you’re expecting colder weather.

Worn Accelerator Cable

While most cars on the road use drive-by-wire electronic throttle control to accelerate, a physical accelerator cable (or throttle cable) are still found in many vehicles. It acts as a mechanical link between the gas pedal and throttle plate.

Over time, this accelerator cable can wear out. This will cause the car to respond more slowly when you press on the gas and it lurches instead of providing smooth acceleration. You can usually see damage to the cable’s outer coating when examining it, making this problem easy to diagnose.

A damaged cable requires immediate attention, as the car can stop functioning when the cable breaks. Be sure to take it to a trusted mechanic to ensure the replacement is done right.

Bad Transmission Control Module

If you drive an automatic transmission car and notice your car jerking or bucking right around the time your transmission changes gears, you may have a faulty transmission control module (or solenoid).

This part is responsible for gear changes when you accelerate. Gear shifts may be delayed or unpredictable and are often harsh and may feel like the car jerks.

When to flush the transmission on Toyota Tacoma

For a manual transmission, most manufacturers say you need to change the fluid every 30,000 – 60,000 miles. Some vehicles may never have their transmission fluid changed, unless there’s a leak or another problem. Other engines have a regular maintenance interval, just like engine oil or filters.

It is important to follow Toyota guidelines on transmission maintenance. If you need to have the transmission rebuilt, that can run you up to $6,000 or more.

How do I know if I need to change the transmission fluid on my Toyota?

Similar to the function that oil has in your engine, transmission fluid lubricates the moving parts in the transmission. When the fluid is worn out, contaminated or missing because of a leak, you’ll start to see – or, more likely, feel – problems with the way your transmission shifts.

Difficulty in getting into gear or staying in gear

A lurching or thumping when shifting. If it’s operating properly, you probably won’t notice your transmission doing its job; if you really feel the shifts, you may have an issue.

Check this too: Symptoms of a Bad Radiator Fan

A lag between pressing the accelerator and actually accelerating. A variety of different issues could cause this, but transmission issues could be one.

Strange noises like whining or grinding.

If you suspect an issue, the best course of action is to take your car to your local Toyota service centre to get it checked out.

How do I check the transmission fluid on my Toyota?

The first thing to determine is whether you’re able to check the fluid at all. Many modern cars don’t have a transmission fluid dipstick, so the only person who can check it is a pro.

But if your car does have a dipstick, here are a few things to keep in mind.

First and foremost, consult your Toyota owner’s manual.
Park your vehicle on a flat surface.
Based on the owner’s manual, decide whether to check the transmission fluid with the engine on or off. Obviously, you’ll have to be a lot more careful if the engine is running.
Apply the parking brake for safety and make sure the vehicle is in Park.
Find the transmission dipstick, which is usually brightly colored and toward the back of the engine.
Remove the dipstick, being careful not to spill or drip any fluid. Wipe off the dipstick with a clean rag, just as you would do when checking the engine oil.
Reinsert the dipstick, then remove the dipstick again to check the fluid level.
If you need to top it off, be sure to use the recommended transmission fluid. If the fluid is particularly low, you might have a leak and should get it checked out.
Replace the dipstick once you verify that the transmission fluid is at the right level.

Toyota Tacoma five speed automatic transmission shifts hard

One of the most common automatic transmission problems is shifting hard. If your Toyota Tacoma has a hard shifting transmission is not only can be uncomfortable to drive, it can be a sign of some serious problems.

Here is a list of practical things that most people can do when their transmission is shifting too hard.

1. Check The Fluid Level

A transmission with fluid that’s low, will not operate normally. That’s because automatic transmission fluid is a hydraulic fluid that transfers the energy from the engine to the rear wheels. Without it, your Tacoma just can’t go.

More often than not, low fluid will cause a transmission to slip, which creates softer shifts. When it finally does grab, it can feel like a harder shift. It is possible for some transmissions to shift harder when they are low, but not too low, even if it is not slipping at all.

Look under where you park the vehicle and check to see if there is any fluid down there. That is an obvious sign there is something wrong.

2. Check the Fluid For Signs of Wear

So, the fluid level checked out. Now it’s time to see if the fluid itself may be causing your vehicle to shift too hard. Transmission fluid that is worn out can cause harsh gear shifts and damage the synchros and clutches.

Checking your fluid can tell you a whole lot about what is going on inside of the transmission. Here’s a good article on using transmission fluid color to help determine what is going on in the transmission. If it is really dark, burnt, or past the time that the manufacturer wants it changed, changing the fluid may stop the transmission from shifting hard.

3. Check for a burning smell

Even if you don’t see the transmission fluid, you can still smell that something is wrong with it. Burning transmission fluid stinks. It doesn’t smell like burning oil. It has more of the smell of burning rubber.

Beware that if you smell burning transmission fluid because it is leaking onto something like the exhaust, it is more flammable than motor oil.

When it is getting burnt inside the transmission case, it’s usually due to it being too old, the level being too low, or your Tacoma having done something that it was never designed to do (such as carrying too much weight).

4. Listen for weird sounds

Listen to your Tacoma as you accelerate and decelerate. A transmission that is going bad will often make a whining noise. Listen for anything out of the ordinary. You already know that your transmission is shifting too hard, so it’s more than likely if you hear any strange noise they are related

This would indicate an internal transmission issue.

5. Check Engine Light

If your Tacoma is shifting hard, and you get the check engine light, there may be a diagnostic trouble code stored in the memory. If the code is transmission related, you can use the information to help you diagnose why the transmission is shifting hard. It’s a heck of a lot better than being in the dark.

6. Internal Transmission Issue

Repairing an automatic transmission is one of the most difficult mechanical projects that there is. If you have used the practical advice above and gotten nowhere, then it may be time to have a professional take a look at your vehicle. They may find internal damage to the transmission, or the transmission controller.

Rebuilding or replacing the transmission in a vehicle is one of the most expensive auto repair projects that there is. You can save money by taking it in when it’s still shifting hard, before the transmission fails altogether.

7. Clogged Filter

If the transmission filter is clogged it can cause the operating pressure inside the case to get too low. This will change the shift quality.

Note: If your transmission is shifting hard, the first thing that you are going to want to do is check the trouble codes if you have a check engine light. If you do not have a check engine light, make sure that the fluid looks good and that it is not burnt.

Take your Tacoma to a transmission repair shop as soon as you have determined that it is most likely an internal transmission issue. The longer that you drive when it is not shifting right, the more long-term damage that you will do.

Toyota Tacoma manual transmission shuts off when clutch is pushed in

Manual cars stall because the driver has let the clutch out too quickly. This means the ‘revolutions per minute’ (RPM) of the engine has dropped too low and the engine has stopped.

You’re less likely to stall if you release the clutch slowly. Don’t release the clutch all the way until you’ve felt the car ‘bite’. You’ll hear the engine engage and you might feel the front of the car lift.

When you do stall

You need to avoid panicking and calmly restart your car. Follow this process to recover from a stall:

Put your foot on the brake.
Put the clutch all the way in.
Put the car in neutral.
Restart the engine.
Select 1st gear.

Check your mirrors and over your shoulder to see if any cars are trying to pass you. If not, drive on forward.

Practise this process on a quiet road. Do it until you can quickly and confidently re-start the car without having to look down at what you’re doing.

4th & 5th gear not engaging Toyota Tacoma automatic transmission

Here are reasons a transmission will not to shift into any gear. Any of the outlined causes below could be the reason.

Dirty transmission fluid

Transmission fluid plays a critical role in the proper functioning of automatic transmissions. In fact, the torque converter, an essential component of automatic transmissions, works on the principles of hydraulics.

With time, dirt, debris, and metal shavings will get into the transmission, affecting the hydraulic. These particles will cause the transmission to slip, lose power, shift hard from 1st to 2nd, or not engage in any gear.

Therefore, it is important to carry out scheduled transmission fluid changes at regular intervals. Read this article, “should I change transmission fluid at 100k miles,” to know when to change the transmission fluid.

Shift lock

If you own an automatic car, you’ll know what shift lock means. When you start an automatic car, the transmission won’t shift from the park to any gear unless you depress the brake pedal. The mechanism that sticks the gear lever until you depress the brake pedal is the shift lock.

This is a safety feature in automatic vehicles that prevents the car from rolling when a curious child tries to move the gear selector. However, this feature can malfunction and prevent the transmission from engaging in any gear.

Fortunately, many automatic transmissions feature a shift lock override. This lets you press down the shift lock and engage the vehicle even when the shift lock is malfunctioning. Visit your owner’s booklet to find out how yours works.

Bad Torque converter

In manual transmissions, the clutch systems engage and disengage the transmission unit from the engine. The torque converter does the same function on an automatic transmission.

The torque converter comprises three key components known as the pump, stator, and turbine. Any of these components can fail and cause hard shifting. When wondering, ‘what causes gears won’t engage,’ remember that a faulty torque converter can also prevent the transmission from engaging in any gear.

Bad transmission control unit

The transmission control unit (TCU), also known as a transmission control module (TCM), is a transmission computer that tells it when to shift gears efficiently. These components are only found in automatic transmissions.

If your car doesn’t move in any gear, an automatic transmission control module could be the cause. If you suspect the transmission control module to be the cause, insert your diagnostic tool to pull out the registered fault codes.

One of the common signs of a faulty TCM is that the car will display an incorrect gear position from the current gear the vehicle is running on the dashboard.

Other signs of a bad TCM are;

The transmission won’t shift when accelerating
Strange sounds when shifting to drive mode – the gears won’t change, yet the RPM increases.
Broken or dislodged transmission linkages

It’s possible for the linkage between the gear shifter in the cabin and the tranny unit to dislodge. This can happen both on manual and automatic transmissions. Though, it could be unlikely the cause.

This cable can disconnect by a rough bump or car accident. It can also deteriorate and break because of age.

If you were asking what causes automatic transmissions to fail to engage in any gears, you have seen why automatic and manual transmissions cannot engage in any gear.

How To Fix Transmission Engaging Problems

Since there are probable causes that will cause the transmission not to enter gear, there are several solutions as well. Let’s look at how to fix transmission problems.

Transmission fluid

Low transmission fluid will cause the tranny to overheat and underperform. Dirty or degraded fluid will lose its lubricating power and may cause the tranny not to engage in any gear.

If low or dirty transmission fluid is the reason the transmission is not engaging, check the state of the fluid and act accordingly. Check the color of the fluid via the dipstick; if it is burnt or dirty, flush and refill it. If it is low, refill it.

Fixing worn clutch Issues

A worn clutch is the most common cause of manual transmission issues. A damaged throwout bearing, clutch disc, or pressure plate can prevent a manual transmission from engaging gears.

Replacing the defective clutch components is all you need to fix the engagement issues.

Connecting or replacing broken or dislodged transmission linkage

Transmission linkages connect the gear lever with the transmission unit. It can be springs or cables under the gear shifter console. If you suspect it, contact a mechanic to diagnose and do what is needed. Reconnecting or replacing it will fix the problem and keep your vehicle on the road again.

Replacing defective torque converter

The torque converter is the heart of automatic transmission. It plays a critical role in engaging and disengaging an automatic transmission. If it fails, it’ll cause your truck won’t move in any automatic transmission.

Of course, replacing it will fix the problem. However, it can fail in many ways. Therefore, I recommend you read this well-detailed article on the symptoms of a failed torque converter.

Replacing faulty TCM

If something goes wrong underneath the vehicle and the TCM cannot compensate; it will cause the transmission to malfunction. Again, the transmission control module can go bad and affect the smooth running of the vehicle. To track if the TCM is the culprit, diagnose the vehicle with a scanning tool.

First gen Toyota Tacoma 4wd manual transmission will not engage 4wd

If your 4wd doesn’t engage, then it could be due to the following:

Bad Transfer Case

The transfer case is the part of the car that uses gears to distribute power between your two axles. If you have problems getting your 4wd system to work, it may be due to a bad transfer case that needs replacing.

Blown Fuse/Electrical Issue

If your Tacoma’s 4wd system isn’t working, it may be due to a blown fuse or an electrical issue. If your transfer case is electronically operated [most modern vehicles], this could be why you are experiencing problems with activating the 4wd system.

Low Fluid Levels

The transfer case contains gear oil that needs to be changed at regular intervals. If the fluid level is low, you will have inadequate lubrication for your gears to engage, leading to problems with activating your 4wd system.

Bad Transmission

If you are still having problems after changing the blown fuse or checking your system for electrical issues, it may be an internal transmission issue. You should take your Tacoma to a mechanic to get it checked out as soon as possible.

Bad Bearings

The bearings play a significant role in the function of your 4WD system. They help to keep everything properly lubricated and functioning smoothly. If you have a bad bearing, it can cause many transmission and 4WD system problems. Therefore, it is important to get them checked out and replaced if necessary.

Faulty Shift Mechanism

The shift mechanism is responsible for changing the gears in your car. If it is not working correctly, it can cause problems with your 4WD system.

Bad Differential

Differentials are responsible for transferring power from the transmission to the wheels. If it is not working correctly, your 4WD system will have problems engaging.

Faulty Driveshaft

The driveshaft delivers power from the transmission to the front and rear differential. If it is not working correctly, your 4WD system won’t engage.

Bad Transfer Case Switch

Most vehicles equipped with 4WD will have a switch that tells your car’s computer that you are using 4wd versus 2wd. When this switch malfunctions or stops working, your 4WD system won’t engage.

Bad Axles

If the axle assemblies are not engaging correctly, you will have problems with your 4WD system. This is usually due to a bad axle that needs to be replaced.

Grinding noise when shifting four-wheel drive engaged auto transmission Toyota Tacoma

Grinding gears is one of the most common signs of a transmission problem. It means that the clutch isn’t completely disengaging from the engine while the gears are still rotation. However, there are numerous reasons why it could be happening.

In most cases, it signifies that there may be internal damage to one or more components that you will want to get replaced. If the problem isn’t dealt with, it will likely only lead to more transmission issues.

Here are the most common reasons why transmission gears will grind, according to the Central Valley transmission repair specialists at Modesto’s own Ralph’s Transmission:

1. Clutch Problems

The most likely culprit is the clutch system. Though automatic and CVT transmissions have their own clutch system that works automatically. If there are any issues in the clutch assembly or damage to any clutch components, it won’t work right and it’s very common for the gears to grind when shifting.

2. Torque Converter Problems

An automatic transmission uses a torque converter and planetary gear system to automatically do the shifting for you as you accelerate or decelerate the vehicle. If you hear grinding while the car is shifting between forward gears, that is definitely a sign of transmission issues and there’s a good chance it’s the torque converter itself. You may physically hear and feel grinding when shifting into reverse, as well, so that’s another symptom to look for.

3. Low Transmission Fluid

Another cause for grinding gears is when the transmission system isn’t getting proper lubrication from the transmission fluid. You may be low on transmission fluid or the fluid itself could be old and corroded. It’s important to get your transmission fluid changed as needed in order to prevent significant internal transmission damage.

4. Gear System Damage

Between the gears themselves and the various sensitive components that control shifting between them, there is always a chance that something can become damaged. This may lead to grinding gear noises or other shifting issues. Sometimes, you may only feel it when shifting between two specific gears. In this situation, a detailed internal inspection of the transmission may be required to get to the source of the problem.

5. Other Internal Transmission Damage

An internal inspection may reveal other damaged components that are leading to your transmission concerns. A transmission specialist will be able to let you know exactly what’s wrong and what it will take to repair the transmission. Sometimes, a full custom rebuild of the transmission is recommended because it’s a more complete fix compared to just replacing one or two damaged parts.

6. Bad Driving Habits

Last but not least, grinding gears is sometimes the driver’s fault. Anyone who has driven a manual transmission vehicle will probably grind the gears when shifting every once in awhile. That’s okay. However, if you do it all the time and really push your vehicle hard with aggressive shifting, carrying heavy loads or crazy driving, bad things will eventually happen. This is a recipe for causing clutch and transmission damage.

These are some of the most common reasons why you might be hearing those grinding gear noises and feeling resistance while shifting between gears. Whether you have a traditional automatic, CVT or manual transmission, you always want to pay attention if the vehicle isn’t shifting smoothly or you hear any strange sounds.

Transmission vibration when downshifting Toyota Tacoma

Below are some reasons why your car is vibrating while downshifting;

Low transmission fluid

One of the simplest faults, and a common one would be low transmission fluid. When this lubricating fluid gets low the parts in your transmission system can grind together and cause vibrations. Transmission fluid should always be topped up at the earliest interval to help prevent damage – it’s an easy way to ruin your transmission.

Worn u-joints

The u-joint compensates for motion and change in position, keeping the driveshaft, differential and transmission connected and spinning freely. Worn u-joints can create a thudding noise when changing gears and when suddenly increasing speeds, the noise can usually be heard from the center to rear of the vehicle. The vibration you experience can mean that the driveshaft has become imbalanced and this can lead to damage in the transmission and other components.

Worn u-joints are more common in rear-wheel drive cars, trucks and SUVs. They are generally inexpensive to fix and replace.

Worn shocks

Shocks are part of your suspension; they help to stabilize the vehicle when turning, braking, accelerating and driving over uneven surfaces. Over time shocks can wear out and one of the symptoms that can present is transmission vibration, particularly on bumpy and uneven roads.

Computer system problems

A symptom of modern-day cars; sometimes car shaking isn’t caused by a fault with the transmission but the computer system instead. Since these complex systems are connected to most parts of the car, a fault in one location can often have a knock-on effect in one area that is not entirely related.

Though the vibration may be coming through the transmission, it doesn’t necessarily suggest there’s an actual problem with it. It can be difficult to determine if vibration when shifting gears is caused by the transmission itself or the computer system.

To find the root cause a mechanic needs to know specific details such as the driving conditions, how long you were driving for and the exact type of vibration or noise experienced.

When was the last time Toyota put a manual transmission in a Toyota Tacoma?

As of 2018, Toyota phased out manual transmission in base Toyota Tacoma models. However, you can still get manual transmission as a trim if you wish.

Toyota Tacoma transmission not working after a transmission flush

When you change your transmission fluid, you should not have any problems shifting gears or maintaining certain driving speeds. You also shouldn’t hear any unusual noises or experience any unusual symptoms.

Below are two of the most common causes after a fluid change.

Varnish Deposits

When you have old or burnt transmission fluid, it may become discolored and cause varnish deposits to build up inside the system. These deposits typically float around the old fluid and don’t really build up anywhere as you continue using the same fluid.

However, once you change the old fluid with new fluid, these deposits get washed away and it becomes sludge that sticks to the filters of your transmission system. This prevents transmission fluid from flowing through the transmission, which results in those strange noises to be heard.

Therefore, you need to flush your transmission before adding new fluid. That is the best way to ensure that no pathways get clogged within the transmission.

Wrong Type of Transmission Fluid

It is best not to use traditional transmission fluid that is petroleum-based because these will leave the most deposits behind. Once these deposits build up on your filter and restrict the transmission fluid from flowing, it will cause the transmission’s components to heat up and create more friction.

This will result in clunking and other noises that you don’t want to hear. Fortunately, there are synthetic transmission fluids which are formulated to ensure that these components stay lubricated and that the gears shift smoothly. You will find this fluid marketed as “trans medic” in most cases.

When to use second gear on a Toyota Tacoma automatic transmission

There are two main reasons why the driver of an automatic vehicle might switch to 2^nd gear:

Towing Heavy Cargo: If you’re towing a trailer, a boat, or another vehicle, you might need a little extra oomph to get moving. Naturally, you might not mind moving a little slower, so it makes perfect sense to ease off the gas pedal and start driving in low gear. The added torque from the lower gear lets you make the most of your vehicle’s power.
Driving at an Incline: Have you ever had trouble driving up a long, steep hill? If so, you probably should have allowed your transmission to downshift into low gear. Your engine will be working hard to move you up the incline, and the extra engine torque allows every burst of power to take you just a little bit further.

Toyota Tacoma 340E automatic transmission shifts when cold but will not shift when hot

There are several things that can cause your transmission to shift poorly when it is warm. The most common causes are low fluid levels, leaks, or worn-out parts. Most of those problems can be solved by regular maintenance or by replacing the transmission gasket and filter.

Low Fluid Levels

One of the most common causes of poor shifting is low fluid levels. When the fluid level gets too low, it can cause the gears to slip and grind against each other. This will cause your transmission to shift poorly and may eventually lead to damage if not fixed.

To check your fluid level, open the hood and locate the dipstick. Remove it and wipe it off with a clean cloth. Insert it back into the transmission and then remove it again. The fluid level should be at or above the “full” line on the dipstick.

If it’s not, add more fluid until it reaches that level.

Leaks

Another common cause of poor shifting is leaking. Transmission fluid can leak from a variety of places, such as the seals, gaskets, or even the pan itself. If there is a leak, it will need to be fixed before the problem can be resolved.

To check for leaks, put your car on a jack and locate the transmission pan. It’s usually located on the bottom of the transmission near the back of the engine. Once you find it, look for any signs of leakage. If you see fluid on the ground, it’s likely that there is a leak.

Worn-Out Parts

As your transmission ages, the parts will start to wear out. This can cause the gears to slip and grind against each other, which will cause your transmission to shift poorly. Worn-out parts will need to be replaced before the problem can be fixed.

To check for worn-out parts, take your car to a mechanic and have them inspect the transmission. They will be able to tell if any of the parts are worn out and need to be replaced.

Toyota Tacoma Maintenance

One of the best ways to prevent poor shifting is by doing regular maintenance on your transmission. This includes things like checking the fluid level, inspecting the seals and gaskets, and replacing any worn-out parts. By doing regular maintenance, you can avoid many of the most common causes of poor shifting.

How to Add Transmission Fluid

There are a few reasons why you might need to add transmission fluid to your car. If you notice that the level in the dipstick tube is low, or if your car is shifting gears hard, then you might need to add some fluid. Adding transmission fluid is easy, but you need to be careful not to overfill it.

To add transmission fluid, start by finding the dipstick tube. This is usually located near the front of the engine, on the side of the transmission. Once you’ve found the dipstick tube, pull it out and wipe it off with a clean cloth. Then, insert it back into the tube and push it all the way in.

Next, find the fill hole for the transmission. This is usually located on the side of the transmission, near the bottom. Once you’ve found the fill hole, unscrew the cap and insert a funnel. Slowly pour transmission fluid into the funnel until the level on the dipstick reads “full.”

Once you’ve added enough fluid, screw the cap back on and check the level again. If it’s still low, add more until it reaches the “full” mark. Finally, start your engine and check to make sure that the car is shifting gears smoothly. If it’s not, add a little more fluid until the shifting is smooth.

Remember, it’s important not to overfill the transmission. If you do, it can cause damage to the transmission components. So, be careful and add the fluid slowly. Also, check the level frequently while adding fluid, so that you don’t accidentally overfill it.

How to Seal Transmission Leaks

There are several different ways to seal transmission leaks, depending on the type of leak that you are dealing with. The most common approach is to use a sealant or gasket sealer, which can be applied directly to the leak and then left to dry.

Other options include replacing any damaged components or using an oil additive designed to help stop leaks from occurring.

To seal transmission leaks, start by identifying the source of the leak. This may involve inspecting your car’s transmission closely for signs of damage or leaking fluid, checking your vehicle’s fluid levels using the dipstick tube, and looking for dark spots on the ground beneath your car.

Once you have identified the source of the leak, there are a variety of repair options that you can try. If the leak is relatively minor, you may be able to use a gasket sealer or sealant to patch it up temporarily until you have time to get your car into the shop for more permanent repairs.

If there are major leaks or other sources of damage, you may need to replace damaged components such as seals, hoses, or gaskets. Additionally, some oil additives are designed specifically to help stop transmission leaks from occurring by helping to reduce friction and increase viscosity within the system.

No matter what approach you take to sealing transmission leaks, always be sure to consult your vehicle’s owner’s manual for specific instructions and guidelines about which products, fluids, and procedures will work best for your particular vehicle.

With a little time and effort, you should be able to fully repair any transmission leaks and get your car back on the road.

How to replace Worn-out Transmission Parts

Transmission problems are often the result of worn-out or damaged components within the transmission system. These issues can cause a variety of different symptoms, including slipping gears, rough shifting, and trouble accelerating.

If you are experiencing any of these symptoms, it’s important to take your car to a mechanic as soon as possible for an inspection and diagnosis. In many cases, worn-out transmission parts can be replaced or repaired to restore the proper functioning of your vehicle’s transmission system.

One common cause of worn-out transmission parts is inadequate servicing over time. As your car ages or gets more miles on the odometer, it’s important to keep up with routine maintenance to prevent serious damage from occurring.

This may include replacing the transmission fluid at regular intervals and having your transmission system inspected periodically by a mechanic.

In addition to regular maintenance, there are also some steps you can take on your own to help reduce friction and wear within the transmission system. For example, changing gears at lower speeds or avoiding hard acceleration or braking can help limit the stress on your transmission’s parts over time.

If worn-out transmission parts are causing your vehicle’s shifting problems, it’s important to have them replaced as soon as possible to prevent further damage from occurring and keep you and your passengers safe on the road.

Whether you opt for DIY repairs or professional servicing, talk to your mechanic about the best options for restoring proper functioning to your transmission system.
