I had codes P0880 and U0101 and the truck was stuck in 4th. After cutting off and eraseing the codes, i cranked it back up and it drove fine. I still can pull the P0880 (TCM input signal) and it wont permanently erase. It will go into P.N,D.and M now but i dont know why i still have that one code.
All i did the day before was replace the fan belt and i laid the fan shroud, with the TCM still attached, back over on the motor. I unplugged the TCM and checked the harness but dont see a problem. Also checked the harness that goes down and plugs into the valve body on the transmission. Can anyone help me out?
