Detecting 6 Common Automatic Transmission Problems

ByTsukasa Azuma-July 01, 2023

There are two types of transmissions that vehicles can be built with. These include either an automatic transmission or a manual transmission. If you have any plan for a long drive out of town driving in a remote area and suddenly you realize that the automatic transmission of your vehicle is not working.

Now, what is your automatic transmission troubleshooting solution? This kind of situation does not arise all of a sudden. However, your vehicle starts giving enough warning signs well in advance, to detect such failures. For that reason, here is the list of automatic transmission problems.

Some of The Most Common Automatic Transmission Problems

If there is a mechanical problem with your vehicle, it will start giving distinct sounds and a lack of response from your vehicle. Not only that, It will release the unusual smell of the burning fuel. In an electrical problem case, the vehicle dashboard might even start indicating!

If you are noticing something out of place in your vehicle, then you should consider it to be a problem sign.

1. Transmission fluid level and leaks

The most common problem is transmission fluid level check or leak. If you see any liquid red or black in the garage under your vehicle, this could be transmission fluid. Don’t panic and get your vehicle immediately checked. Auto transmission problems mostly can be avoided by changing the filter and fluid in a timely manner as per manufacturer specifications.

 2. Slipping transmission

If you are driving in a certain gear and suddenly, the gear automatically shifts to another one. It also appears unusual sound coming from underneath the vehicle. In some cases, your vehicle suddenly starts falling underpowered.

It could be a sign of wear and tear in your transmission line. As terrifying as it sounds, you need to get your vehicle checked immediately.

3. Electric component failure

Imagine while driving home, you detect damage in the vehicle speed sensor or some fuse. Feeling bad, right? Yet it can get even worse since it could be an electric component failure.

Of all automatic transmission problems, this may not allow the Electronic circuits to control the transmission. You will have a vehicle that cannot work properly. Sadly, your vehicle must be fixed this issue as soon as possible.

4. Broken flax plate

In the list of automatic transmission problems, a broken flax plate is the easiest to spot. You can check the flax plate state just by looking.

A broken or damaged flax plate (alternatively called flywheel) will not transfer complete engine power to the transmission.

5. Gear shift lock

Imagine you can only drive on the street in the first gear. Terrible right? In the automatic transmission problems list, the gear shift lock is by far the most dangerous. The vehicle goes into the first gear but refuses to shift into another gear. This could be caused by the transmission shift solenoid. It pushes the transmission fluid throughout the system and if it is broken or jammed could result in not transmitting enough power as you drive. When automatic transmission problems shifting gears happen, shift lock release mechanism might be the best solution. Make sure you know how it works.

6. Transmission overheat

One of the automatic transmission problems that require much attention is the overheating transmission. Especially, if u are owning a Toyota car, this is a common issue among Toyota automatic transmission problems,

This usually happens due to burnt, dirty, or no fluid. The driver should replace this fluid immediately to avoid further damage to the vehicle. Whenever you feel such issues with the transmission, you should bring your vehicle to professional vehicle mechanics.

Note: A few small notes while driving with an automatic transmission: only use the right foot for both the accelerator and brake pedal; Always apply the brake when changing manual gear and absolutely do not shift to N when moving.

In addition, some models that use an anti-slip differential may have a manufacturing defect that causes a rattling sound when steering, and loss of control when cornering. The annoying sounds of idling once again indicate that the transmission fluid is due to be changed, or could be a sign of more serious mechanical damage. However, most of the noise is generated because the bearings or gears in the gearbox have worn out and need to be replaced.

Final Thoughts

An automatic transmission car is a type of car developed later, with many new improvements to bring the most complete experience to the user. However, in addition to the outstanding advantages of an automatic transmission, this transmission still has some disadvantages or problems. Hopefully, you will find useful knowledge in our article.

A transmission is known as the brain of the speed machine. Apart from regulating the engine speed, it transfers the motor’s power to the wheels. Basically, it is a fluid driven component. A small leak the transmission system can make it faulty. A transmission usually gets malfunctioned, when the fluid level goes low. A clogged transmission fluid filter plays a key role in making the transmission system sick and unreliable. That’s servicing the transmission from to time is recommended. And when it comes to servicing vehicle’s transmission system, service it at an authorized car service center.

Car slipped into reverse and she hit the car behind her. Thank God she, her passengers, and the people in other car are alright. However, she now has pain. WHY AND HOW CAN A CAR SLIP OUT OF DRIVE, INTO REVERSE?? This is VERY DANGEROUS.

Did you put correct fluid type for your gear box? if the fluid wasn’t correct for your transmission, probably you might be already damaged clutch packs of your cars that hold power from engine to car’s tires. so you either need transmission rebuild or buy new gear box.

Hi please could you help me? I have a Toyota yaris 2006 model which has a combine automatic and manual transmission. when driving at a point the automatic transmission warning light comes up, if that happens the gear box freezes and the car stops. this mostly happens when the car slows down to say 10-5KM/h or at a complete stop. when that happens I put off the car completely, push the gear to N and then wait for some seconds or a minute for the warning light to disappear after which I start the car and drive. the frequency this time is appauling and I am afraid it can cause something real bad. please what do I do, I have taken the problem to various mechanics to no avail. Please help me.

Please good people help out. I have an automatic Toyota Runx 1.5 with 1nz vvti engine. While driving it sometimes make a loud knock sound but it’s as if it’s in the gearbox. Sometimes when you come to a complete stop and you take off it struggles to accelerate and later take of with a high speed, and while it’s in high speed it’s charging the gears backs and u can hear a knock in the gearbox. So far I replaced the gearbox 3 times, replace air sensor, knock sensor and cut out the catalytic converter, replaced spark plugs, ignition coils and the throttle body. I also replaced the fuel filter in the tank and changed the computer box(ecu) but the problem is still there. The car doesn’t show any fault code on the diagnostic tool. Please help here is my email

I have a problem:

I have Nissan X-Trail 2003/3 model (Auto) and looks it’s not changing gear and still on first gear. When I travel a steep hill, it should change the gear auto but it does not and climbs the hill on the same gear. When Travel on high speed 80-90kph, it gives a high cry from the engine.
I don’t know what’s happening and need advise as to what’s causing it so I can fix locally asap.

Many thanks.
Irap.
