1992 ford f150 transmission shifting hard

Asked by May 22, 2017 at 05:01 PM about the 1992 Ford F-150

Question type: Maintenance & Repair

it started shifting hard into 2nd gear and sometimes the transmission slips
but it shifts smoothly into the other gears, i took it to my transmission shop
and he scanned it and it was throwing 2 codes for the throttle position
sensor so i replaced it and it seemed to shift fine for about a day then the
check engine light came on and it started shifting hard again BUT only
when shifting from 1st to 2nd and the check engine light wasn't on before.
when i get on the highway and keep at a steady pace it slips in and out of
gear. its a 5.0 V8.

Sounds like there are a few miles on the transmission, may be getting time for it to be rebuilt. Try putting some Trans X into the transmission, may help for a while.

the truck has 116k miles on it and i dont know if the transmission has ever been replaced or rebuilt. thanks!


May want to change the fluid and filter, and add the Trans X in at that time. Do not get a transmission flush.
