I have Pontiac G6 which is giving me OBD2 code U0101. I went to a Junk yard and got a TCM and tried to replace it. It still gives me U0101 plus U0001. Can I replace a TCM without Dealer involved?

No, it has to be flashed. You may not be able to flash a used one to the car. It may have to be new.

Did anyone check this system to verify the tcm has failed?
