I own a Chevy Silverado 1500 and I'm trying to figure out how to reset the transmission module.

★ Top Answer

To reinitialize the transmission control module in a Chevy Silverado 1500, start by inserting the key into the ignition and turning it to the second position without starting the engine. Then, fully depress the accelerator pedal and hold it down. After about 10 to 12 seconds, switch the ignition off twice, leaving the key in the ignition. Once the key is removed, release your foot from the gas pedal. Wait for approximately 2 to 3 seconds, then turn the key to start the engine. Drive the vehicle as you normally would for 10 to 15 minutes so that the TCM can adapt to your driving habits.
