The wiring all came pre ran for the engine and trans. Best I can tell the vss wire runs to the ECM then back out to the tcm. I've checked everything I can think of still just first and second. I hooked a laptop up to the tcm and its showing mph.

Ok thanks it came with some software but I don't see that working in this situation. It just allows you to change shift points, line pressure, rear end gears, tire size, and converter lock up. But I'm inexperienced in that area and wouldn't know where to start or adjust on the shifting or converter stuff
