I have a 1994 F-150 5.0 litre, and when the transmission shift into all 3 gears, you get whiplash. the engine will rev some what high then all of a sudden, the trans kicks in, there is no smooth shift in the tranie. Is there an adjustment on the endgine, or tranie to correct the shifting problem? thanks

Take a look at your tranny fluid. check the level and also see if it has any metal in it. Does it smell burnt? Sounds as if a valve in the valve body is sticking. If you see metal flake in the fluid your tranny is on its way out. If not you could try a flush and new filter.
Good luck.

Trans filter and fluid are fiine, I checked the speed sensor on the rear axle, that's ok, but I noticed that the speedometer sometimes does not work, when that happens, the truck shifts hard, but when the speedometer works, it shifts fine???? Any ideas. Thanks

Found the problem, the speedometer is electonic, I took the dash apart, and found a loose wire behind the cluster. Shifts perfect everytime.
