Is the PCM or TCM responsible for the electronic shift control in a 93 ZJ with 42RE? I think I have a failure in Electrical component I'm thinking its the PCM that is glitchy causing my Not returning to first after driving. It's been to trans shop and had the solenoids and governor and harness done but still wants to not return to 1st every time. getting old fast cause I want to build/ lift this ZJ, Its something to do with voltage or ground going to the trans through the harness but I can't find what is supposed to send that signal to the trans so far....HELP Please!!:cheers:
