Codes 452 and 634 and no reverse lights
I've repaired wiring issues replaced grounds and sensors. Replaced leaking capacitors inside pcm now down to my last codes. Before repairing the pcm I've heard of bad grounds from the pcm I came across an old tsb saying to add another ground to pin 46 for the exact issue. Trans slips bangs into gear feels like it starts in a higher gear I've cleaned the rabs sensor or vss sensor, cleaned and lubricated vss , mlps, main bulkhead, and pcm connectors. All fuses are good. I think I have a defective mlp sensor
