I did the auto to manual trans swap in a 99 tib. I also swapped the ecm and the engine wiring harness. I have code P1613 mil request from tcm. I have all the info from HMA service. It does not tell me what the input to the ecm that turns the light on. If you have a shop manual I need to know if the ecm is looking for power,ground,vpower or what. If I can figure that out I can supply it to the wire to keep the light off. I dont understand why this code is setting. The tcm is not in the car and the ecm and wiring is from the manual trans car.
