Any wiring harness pros out there?
I'm only getting 2.6 volts on the communication wires (3 tan/1 tan with a black stripe) on my 6L90 Trans TCM.
It's stuck in limp mode (3rd gear) and throwing all kinds of trans DIC messages.
I have test hung a known good TCM and it does the same thing.
I traced and cleaned up all of the grounds that I could find.
I have the harness half way pulled out to check for damage, but can't seem to find anything.
Any suggestions or recommendations are welcome!!!
