Steps to Resetting Transmission Control Module

Step 1: Turning Key Position

Before you start resetting the transmission control module is to go through the key position. First of all, you need to change the position of the key and set it to 2.

Check your car’s dashboard lights. Make sure the dashboard lights are visible. When the lights are visible, you are ready for the next step.

However, in the initial step, it is not necessary to step on the gas pedal and start the vehicle. It does not do so initially. After specifying the essential key setting, be careful.

Keep your ears open. You will certainly hear various sounds. There will actually be two clicks. And also after that, the dashboard lights will come on. Also within this scenario, do not turn on the engine.

Step 2: Press gas pedal

Once you have finished with the previous step, you should move on to the next action, which is to step on the gas pedal.

Now all you have to do is press the accelerator pedal. Be sure to press it down. Press the accelerator pedal all the way down in order to activate the kick-down switch.

Activating the Kick-Down switch is all you need. Keep pressing the foot pedal, and continue to the next step.

Step 3: Keep Waiting

Now, if you are here to reset your Chevy’s transmission control module, you should be a little patient. You can’t expect faster changes.

However, you only need 10 minutes in this step. As mentioned above, do not take pressure off the gas pedal.

Within this time frame, all you need to do is stick around. 10-12 seconds will be enough for the gas pedal to start working for the full reset process. Press the pedal and wait.

Step 4: Turning the Key Off

After putting your foot on the accelerator pedal for about 10-12 seconds, you need to go ahead and return to the key. However, do not release the pedal.

Note that you have to do all this while keeping your feet on the pedal. Remember before you had the keys turned to 2? Yes, now you have to go through it and turn it back to its previous position.

All you need to do is turn them off. With your hands, turn the key to zero. You may be in the habit of setting the key to zero and removing it.

However, within this scenario, you can refrain from doing exactly the same. You cannot remove the key. After turning the key to its previous position, you must keep the key there. One thing to keep in mind is that this procedure does not apply to all models.

So, check your model and also recognize whether or not you are required to remove the key. However, in most Chevy designs, the key is not removed.

Step 5: Releasing Gas Pedal

Once you have set the key in the home position, you can stop pressing the accelerator pedal.

Many times some people get careless and take the pedal out even before turning the key, but we don’t want you to repeat the same mistake!

Therefore, make sure you have stayed with your feet on the pedal during the previous step. And only take the force off the accelerator pedal when you have finished turning the key to the zero position.

Step 6: Wait Again

We can understand that you don’t want to wait. But doing so will help make the restart process less complicated. After taking your foot off the accelerator, you should give your Chevy a rest.

Your engine needs to rest for about 2-3 minutes. Make sure you have kept the key left in the ignition where it is in the off position. Do not shift the key around. Take some time and then move on to the next part.

Step 7: Ready

Therefore, you are almost practically done with the procedure. You have actually done the Engine Control Unit process along with the Transmission Control Unit process.

All you need to do now is drive! The TCU process, along with the ECU, will certainly work cooperatively. They will definitely try to get to know your driving technique. They will certainly check your driving pattern and take care of that too.

When it is done with the TCU as well as the programming of the ECU, you should take your car for a ride. The trip may take 15 to 20 minutes.

You must keep in mind that you are educating your engine exactly how you drive. Therefore, do not try to go on a race. You don’t race your car all the time, do you?

If not, then make sure you choose a decent speed. The speed at which you usually drive your car will be the speed in this case too.

Make sure the transmission you select is typical and smooth. That way, you can move your gearbox effortlessly and have something new in your car.

What Causes a Transmission to Get Stuck in Gear

4l60e Transmission Control Module Location

The transmission control module is usually located at the rear of the transmission case, precisely under the cover. It is located below the engine control module. On some models,* it can also be found under the hood near the battery or under the interior center console.


The latest generation 4l60-E transmission has three cast aluminum alloy parts: hood, main body, and rear cover. GM reduced the package to 21.9″ long, equivalent to a 15.4″ manual transmission. The input shaft has 30 slots. The automatic transmission usually has its cooling inlet on the right side with a square oil reservoir.

The key distinction of the 4L60E automatic transmission (1997-2006) from the early 4L60E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982- 1989) is the “six hex bolts” of the rear output or rear cover.

The 4L60E can be found in the back of almost all GM applications, and there you can locate the 4L60E transmission module, including C/K Truck, Sonoma, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Silverado, Blazer, Bravada, Firebird, Camaro and Corvette among others.

Damage to the transmission control module is usually caused by:

  • Voltage overload
  • Short circuit in the circuits
  • Shortcircuit in the actuator or solenoid circuits
  • Shortcircuit caused by water in the circuitry
  • Vibration and/or thermal stress.

How do I know if my transmission control module (TCM) is bad?

10 main signs of a defective transmission control module

  1. Unpredictable shifting
  2. Problems shifting at higher speeds
  3. Downshifting problems
  4. Delayed shifting
  5. Poor fuel economy
  6. The transmission does not shift gears when stationary.
  7. The transmission does not upshift when accelerating.
  8. The car is stuck in neutral or first gear. 
  9. Not shifting gears
  10. Check Engine Light

Will a bad TCM throw a code?

Does a TCM need to be programmed?

If you install a new TCM, it is necessary to program the transmission control module, and the programming must be done at the vehicle.

Side Note: You should never attempt to service the vehicle if you have already installed a new transmission control module, as this could cause premature failure of the automatic transmission.

How much does it cost to replace a TCM?

The cost to replace a transmission control module will be in the $500 to $1000 range. Also expect part costs in the $400 to $700 range. But for all that, you can also order a new transmission control module (TCM) online and ask them what their rates are for the job.

What does lost communication with TCM mean?

Diagnostic Trouble Code (DTC) U0101 shows that contact with the TCM has been lost. When the TCM does not accept or transmit a response via the CAN bus, this code is displayed. The TCM is the computer that controls the vehicle’s transmission.

U0101 code is usually caused by one of the following factors: The battery is almost empty. A faulty TCM. The TCM circuit is malfunctioning.

How do you reset a Chevy TCM?

To reset the TCM, I turn the key to the ON position, step on the accelerator pedal for 10 seconds, turn off the engine, release the accelerator pedal and wait 5 minutes for the engine to restart.

How do I reset my Chevy ECM?

Remove the negative battery cable nut with a socket wrench or wrench. Remove the battery cable and set it aside. Turn the headlight switch to the “on” position to drain the remaining power from the ECM. Wait at least 10 minutes before turning it back to the “off” position.

Will disconnecting battery reset TCM?

Disconnecting the battery would not return the TCM to its default settings, and you would need to use a transmission scan method to do so. Simply disconnecting the battery terminals will not complete the phase or solve the gear shift issue.

How long does it take to reprogram a transmission control module?

Reprogramming usually takes 30 to 40 minutes. Programming is completed once the machine has finished loading. The data is passed to the PCM memory chip.


Now that you understand exactly how to reset transmission control module, you’ll definitely never get tired of the same gearbox! The method our experts have pointed out is tremendously easy. All you need to do is keep the warnings in your mind, as well as do your best.
