Automatic Tranny Question
 

to start...sorry for the long post....my brother has a 92 reg cab d250 with the auto tranny w/overdrive. the overdrive is not working and he bought the truck from our stepdad. stepdad said that a plug is loose and has to be zip tied together in order for it to work and the replacement part is around $300. i was wondering if anyone knew what the heck he is talking about and if there is a way to correct the problem without having to buy an entire new harness for that price. any help would be greatly appreciated.

throttle position sensor on top on injection pump, see "pot fix" or 3.0 tps under drivetrain of sticky, id go with the 3.0 tps i dont like my pot fix that much

^^yep real simple fix

thanks alot guys, hopefully i can get it corrected and not have to worry about it again.
