Is there a way to reset the TCM?
Only way i know is with a tuner which i doubt he has. The procedure I saw shows putting the transmission in N with the key ON but not started. Then turning to off, put back in P and then turn to ON, wait, then start. When I put in in N without the car running, I got a message that said Transmission Ready and a progress bar.
How much does it cost to replace a TCM on a Duramax?
My TCM started giving me issues on my 2013 Chevy Duramax. Got some quotes, $1100-1300 to replace the TCM. Luckily did some more research and found DDP’s TCM. Ordered it, plugged it in, and my truck was back in action.
Where is the TCM located in a car?
While swapping out a box might seem simple, the TCM is located inside the transmission in many modern cars, trucks, and SUVs. Opening the transmission is a laborious task, which is why it is reasonable to expect labor costs of at least $300 to replace the transmission control module.
