I have a 1992 Ford F-150 Pickup, Automatic transmission, short bed, regular cab, 2WD, about 250,000 miles on it. I use it to pull a 2 horse aluminum horse trailer. I’ve had the transmission rebuilt twice. It drive ok… but I don’t think it’s change gears at the right time. My question: Should I have it possibly rebuilt again or is it time to buy a new transmission?
It may be the TV cable is out of adjustment. This transmission has a manual valve body, and is not computer controlled. The transmission uses a cable that runs from the transmission to the throttle body. This is the TV cable (throttle-valve). The transmission uses this cable to help determine the proper shift points. If it is out of adjustment, the transmission shift points will be off.
I forgot the method to adjust it properly, but a Chilton’s or Haynes manual will have it. Check your local library. I’ve seen older car repair manuals there for borrowing.
