Steps to Resetting Transmission Control Module

Steps to Resetting Transmission Control Module

Step 1: Turning Key Position

Before resetting the transmission control module, it is necessary to check the key position. To begin with, you must change the key position to 2. Check that the dashboard lights are illuminated.

However, it is not necessary to step on the accelerator and start the car in the first step. Be careful when setting the ‘KEY’ position to the correct number.

Keep an attentive ear, there will be two clicks. At the same time, the dashboard lights will illuminate. You should not start the engine yet.

Step 2: Press gas pedal

Once you have finished with the previous step, now you just have to step on the accelerator pedal. Make sure you press it all the way down.

Depress the accelerator pedal all the way down to activate the kick-down switch. Keep depressing the pedal and continue to the next step.

Step 3: Keep Waiting

Now, if you have come here to reset your Chevy’s transmission control module, you need to be patient.

All you need to do during this time period is to stay for about 15 seconds depressing the pedal, which will be enough for the accelerator pedal to start working for the full reset procedure.

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 let go of the pedal.

Note that you have to do all this “resetting” by keeping your foot on the pedal. Remember before you had the keys turned to 2? Yes, now you have to go through it and return it to its previous position.

All you have to do is turn them off. With your hands, turn the key to zero. After turning the key to its previous position, you must keep the key there.

Step 5: Releasing Gas Pedal

Once you have turned the key to the home position, you can release the accelerator pedal. Make sure you have kept your foot on the pedal throughout the previous step.

And only release the accelerator pedal when you have finished turning the key to the zero position.

Step 6: Wait Again

We realize that you do not want to wait. However, the restart process takes a little time. You must give your Chevy a rest after taking your foot off the accelerator.

Your engine should be off for approximately 5 minutes. Check that the ignition key is in the off position. Do not change the key. Take your time!

Step 7: Ready

You are practically done with the procedure. You have actually done the Engine Control Unit (ECU) process along with the Transmission Control Unit (TCM) process.

All you need to do now is drive! When done with the TCU as well as ECU programming, you should take your car for a drive. The drive should take about 20 minutes. The TCU process, along with the ECU, will certainly work cooperatively.

They will try to learn your driving technique. They will certainly check your driving pattern and take care of that as well.

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.


What makes a TCM go bad?

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?

Yes, if you use an ODB-II scanner, it will throw some error codes specific to a faulty Transmission Control Module (TCM), including codes such as P0613, p0700 transmission control system, P0706, ETC.

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.

    • Follow up. This was a quick and easy fix for my Terrain. My gas mileage doubled! With no changes made to driving pattern or parts replaced. I don’t know what caused this but I can tell you what fixed it! Thanks author(s)! I am no mechanic, I’m just a girl. A little history on the Terrain, it had been parked for nearly two years and then drove and then drove minimally for the next two years that may have had something to do with it’s performance and pitfalls.
