i have had my check engine light on for a while now. it was thrown by 2 o2 sensor codes, a misfire cyl 3 code, and a manufacturer tranny control code. now, i have replaced both o2 sensors, plugs wires cap rotor ign coil, and the o2 codes and misfire codes have gone away, but my ce light is on still from the tranny code. does anyone know what this could be being thrown by? my tranny doesnt slip and it shifts when its supposed to and all in all it seems fine. its got 122000 on it along with the engine and body and everything. its a 96 auto 4x4 aw4 np231. any ideas on what could be causing this? i heard to start from the solenoid but im not sure which one of them it could be. any advice would be greatly appreciated, havent been let down on this site yet. thanks guys. also i might add that i have bypassed my neutral safety switch to diagnose an earlier problem which has since been solved. could this be throwing it??

 

What code?
More than just "Manufacturer Transmission Code" is needed. We need the actual number.

 

sorry the obd2s are kinda vague. i believe its po700? thats what the code read tho was manufacturer control transmission..
