97 k1500 5.7 no inputs
I have a 97 k1500 5.7 that I swapped transmissions on. When I first installed this transmission everything was working fine (had all my gears and engine was running good).
I had to pull the transmission to swap out the pump, when I reinstalled it I lost map, maf, o2 signals, and lost 2nd and 4th gear.
I have tried finding any connections I missed but am unable to find anything. I was told that’s there is a ground that goes from the transmission wiring harness to the transmission bell housing but I couldn’t find that either. I am open to any suggestions please and thank yall.
