I read that reprogramming or resetting the TCM can help to solve, how can I do this? The only option is to pay a fortune for the HP Tuners? I just want to reset to see if my transmission is back to normal.
I have not been doing well for a few months now and I am selling my stuff, and this just happens to me. I want to fix the fault to try to sell the car so I can stay alive. Thanks |
Take it to a chevy dealer and have them perform a transmission re-learn.
