Turn The Key On

Start the resetting process by setting the key position to 2. Then the dashboard light will turn on to confirm that you are doing the right thing. Also, you will hear two clicking sounds.

Do not start the car at this moment.

Press The Gas pedal

After turning on the key, press the gas pedal all the way down to the bottom. Here, you need to wait for around 15 seconds. At this point, you may make a mistake often. Keep pressing down the gas pedal and give your TCM time to reset.

Turn Off The Key

While pressing down the gas pedal for more than 15 seconds, turn off the key in the previous position. It is the reverse of the first step. However, you do not have to remove the key from the ignition. Let it be there and follow the next step.

Release The Gas pedal

Once you turn the key in the home position, you can release the gas pedal. But never release the gas pedal before turning off the key. After that, there is nothing much to do rather than waiting.

Giving the truck around 5 minutes will ensure a successful reset. You should not hurry and start the truck right after releasing the gas pedal. It will not give the result that you are expecting.

Drive The Truck For 15-20 Minutes

Since you have done all the steps correctly, it is time to go for a test drive. You can drive for around 20 minutes to improve the TCM configuration and work smoothly. After that, you’re resetting procedures are complete. Now, you should not have any transmission problems in your Chevy Silverado.

That is how you can reset Chevy Silverado TCM. However, there is another way to reset this. It is called a hard reset. Let’s talk about that further.

Hard Reset TCM for Chevy Silverado

If you know how to locate TCM on your Chevy Silverado, it would be an easier and most reliable way to go for a hard reset. Usually, you will find it on the driver’s side of the engine. It should locate near the firewall or somewhere in that area. It can vary from model to model. Although it is called hard reset, it is the best method to reset TCM. Here is how you can do that.

  • Disconnect the battery by pulling out the positive and negative terminals using a socket wrench (check out a good one here) just to ensure safety precautions. Some say disconnecting the battery is enough to reset TCM. I do not agree with that. If you want to perform a proper reset (hard reset), disconnecting the power source is not going to help that much. Thus, you have to continue with the next steps.
  • Now, locate the TCM on your truck. It should be connected with a larger cable. Gently pull out all the cables and disconnect TCM from the engine.
  • Then, wait for a few minutes (5-10 minutes)
  • Finally, reassemble the TCM and then connect the battery again.

It should do the job and reset the transmission control module. By doing a test drive, you can check if it is working fine or not.
