Automatic transmission no reverse, all forward gears shifts fine, correct transmission oil and level is good, oil doesn't smell burnt. Need wiring diagram for PCM, for vehicle listed above 2.4L Vetec engine. I will check for broken or shorted wires. Any suggestions would be helpful at this point. Thank you inn advance.

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?
