No speedometer, back up lights, tc lockup???
The car is an 87 GTA, L98, 700R4
After my engine swap, I have no speedometer, back up lights or torque convertor lock up.
I have a couple of questions about this. Does the signal to lock the torque conveter go through the ECM, then the brake switch, then to the transmission? That's what I think I see on the wiring diagram. Thoughts?
Also, during my search on the speedometer problem, I found that the rectangular yellow box next to the ECM controls the signal conversion for the speedo. Is that right?
Where should I start?
