I have a 2008 ford f250 with 5.4 liter gas engine, auto trans. Today truck stopped driving, starts and runs no problem, when shifted into gear won't move, no codes have come up, check engine light not on. The service light came on when it happened, but then went out. Happened on interstate off ramp. Previously had an issue when towing and used tow/haul mode, began to shift rough and service light came on until tow/ haul mode turned off. Any ideas?

I assume this is an automatic?
If the shift linkage is not damaged (jammed or disconnected the usual answer is the governer valve in the transmission is sticking.
The fix for this normally involves pulling the trans out stripping it apart cleaning the governer valve new seals gaskets and reassembling.
(translated lots of money) try using a auto trans flush to clean all the gunk out of the transmission. Run the trans through all the gears with the trans flush and try driving it (only short distance test drive as its not proper trans fluid) see if you can get it out of first gear (flatten the gas pedal and let the engine go to max revs on short bursts) once it shifts once or twice go back and remove the trans flush fluid and replace with correct specification auto trans fluid I would also change the transmission filter at this point if it was mine .
This transmission shifted smooth and strong through all gears until today when it stopped all of ... Any idea on where we should start tackling this issue? .... Also, make sure that the pressure tester is not leaking or you will run the tranny dry(use ...
1999 dodge 1500 5.2 will not shift to second once the engine reaches normal temperture or I shift from drive to nutural and back to drive then it will work fine untill the next time I stop. filter, fluid, shift slenoid,governor sensor have been replaced.
Sounds like the shift kit is warn out in the transmission. The overdrive line may not be able to provide enough hydrolic pressure to engage the gears to move the truck. When you switch to regualr drive, that line is able to build the hydrolic pressure to engage the gears. At a certian speed (for the transmission, certian hydrolic pressure) there is enough pressure to engage the gears in overdrive, but go below that, and you have to start in drive again. If this is the case, there is no easy fix for that and I recomend taking it to a transmission shop to have your shift kit examined. Opening up an automatic transmission requires specalized tools, clean shop enviroment, and knowlage more then the average back yard machanic has.
