I just finished putting an engine in a 98 SHO and I am getting the TCC electrical fault code. The car was sitting for quite some time but the tranny appears to be a fresh rebuild, with all new seals and it is very clean and the fluid was new but now that the car is running the O/D light flashes and I get this code, so I swapped The TCC solenoid and that is not the problem and the car is still like jerking at a constant 55 or any speed around there when your cruising at the same speed. Thanks for any input!
