OBD1 ECUs will not control OBD2 trannys. All OBD1 automatic transmissions had was 2 lockup solenoids. OBD2 has those plus a mainshaft speed sensor, countershaft speed sensor, linear solenoid and 2 shift solenoids.

 

i dont need it to control the tranny. Its stuck in 2nd gear, he races circle track.

 

Then just leave it disconnected.

 

i did leave it disconected and when i turn power to the key, you can hear that it does not give power to the fuel pump to prime it.


Any suggestions? I look at the pin for B which controls the tranny. There has to be something im missing for me to make this work.

 

any ideas?
