I’ll try to make it short and sweet. Had tranny problems and had it rebuilt by local shop, 10 days later (it was suppose to take 4),went to pick it up on a Friday in a hurry before they closed, everything  was OK according to shop ,took car without testing it. On the weekend noticed there was NO OVERDRIVE, and NO REVERCE LIGHTS. Took it back on Monday , shop gave me a COMPUTER PROBLEM story , changed computer still had the same problem , now it’s a wiring problem , shop says they couldn’t find wiring diagram anywhere (including Dodge) because car is a true 95.(built in 94). After $2500. Shop says I have to  have wiring checked and computer reprogram by Dodge.
Have the car 4 years never had a any problems. Does anyone have any suggestions or  HELP.

I can get you a wiring diagram if you need it probably.

okay, i don't know a whole lot, but because you said "overdrive" i'm guessing it's an AT?  i had an MT rebuilt, and my reverse lights didn't work either afterward.  i don't know if this helps, but on the MT there's a separate sensor for the reverse lights.  i picked one up at a junk yard off a busted tranny.  they didn't even charge me for it, and it fixed the problem.  no idea about the overdrive though...
