I finally installed my 4L80E in my 82 c10, everything hooked up great.
However I am getting several error codes and erroneous data.
I have checked and rechecked all the wiring and connectors.

Error Codes:
TOT Error
Over Temp
TPS Error
Batt Error

Erroneous Data:
Trans Temp 255 (when cold)
Bat Volts .5 (Meter reads 12+)
TPS at 34% (Set at .5 volts idle and increases as throttle is depressed)

I am pulling my hair out with this thing, I tried to call TCI, but they are gone for the weekend. I am guessing the controller is bad, but if anyone has experienced this your help would be greatly appreciated.
Thanks!

Main wiring harness connector on transmission is plugged in 180* out. Flip it around. Yes I realize how old this post is
