Automatic transmission no reverse,all forward gears shifts fine, correct transmission oil and level is good, oil doesn't smell burnt.

Good morning,

I attached the wiring diagrams for you for the transmissions. I singled out the PCM for you as well.

Most of the time, this is a mechanical issue not an electrical issue.

Do you have any codes in the system?
