How to reset the transmission control module in a Chevrolet?

Brake Caliper

In order to fix shifting problems or enhance the performance of the transmission, you can reset the Chevrolet's Transmission Control Module (TCM). Resetting the TCM may be necessary to re-calibrate the transmission, even though it regulates the gear shifts and adjusts to your driving style. The TCM on your Chevrolet can be reset using the steps listed below:

Turn the Ignition Key to the "On" Position

  • Insert the key into the ignition and turn it to the "On" position without starting the engine.
  • Leave the key in this position for approximately 5 seconds. This will allow the system to power up but not activate the engine.

Press the Accelerator Pedal

  • While the ignition is in the "On" position, press the accelerator pedal down slowly all the way to the floor
  • Hold the pedal down for about 10 seconds. This action sends a signal to the TCM to enter the reset mode.

Turn the Key to the "Off" Position

  • After holding the pedal down for 10 seconds, release it and turn the ignition key to the "Off" position.
  • Do not remove the key; just turn it off and leave it in the ignition for a moment.

Wait

  • Wait for about 2 minutes with the key in the "Off" position. This allows the TCM to reset fully.

Start the Vehicle

  • After waiting for 2 minutes, start the engine as you normally would
  • The TCM should now be reset and the transmission will begin to recalibrate itself based on your driving patterns.

Test Drive

  • Take the car for a short test drive to see if the transmission is shifting more smoothly and to help the TCM learn your driving style.
  • Pay attention to how the transmission behaves, as the reset might take a little time to fully adapt.

When to Consider a Professional Inspection

If resetting the TCM does not resolve the issues you're experiencing with your transmission, there may be a deeper underlying problem that requires professional attention. Persistent transmission issues can be a sign of more significant problems like worn-out components or a failing transmission.
