95 EV - Won't turn over, PRND Display shows D when actual is P.
Diagnostic reports 'not able to read Transmission Multifunction switch F125'
Replaced the switch with new, same issue.
Hard wiring pins 6&7 of the 7 pin connector at the transmission, does allow me to start.
As well I have noticed a very erratic PRND display.
I have cleaned up every Ground lug and battery connection I can find.
The PRND is no longer erratic, but still lands on D, while in P, and won't turn over as a result.
The PRND display has been erratic for a few years, but never prevented starting.
Failure to turn over just happened out of the blue. It was fine the day before.
I am at a loss at the moment. I am starting to think it may be the Transmission Control Module.
As I have also replaced the PNP relay to no avail.
