Depends on year of truck if it doesn't have over drive and even then maybe there is a vacuum line going to shift module on trans mission check and see and if so see if it came off at transmission and if not trace it up to motor
If your transmission is not shifting into third gear and overdrive it could be a parking pawl. This prevents the transmission from rotating.
what would transmission not to shift in to overdrive
The transmission for the 1996 Chevy 3500 could be jumping from overdrive for several reasons. The transmission could have a vacuum or electrical problem causing it to come out of overdrive. Or, there could be an internal valve problem causing this to happen.
One of the reasons a transmission might not shift into overdrive could be a problem with the belt drive inside the transmission. Belt drives can be stretched over time. Another reason could be that the transmission fluid is low or very old or the filter is clogged.
could be a fuse or the O.D. solenoid

Not if you have an automatic transmission.
If your 93 Nissan Pathfinder transmission won't shift into overdrive, check the transmission fluid levels. Ensure the fluid is at the proper level.
Could be low fluid,a bad sensor or transmission going bad.
Your transmission might automatically shift out of overdrive while driving on the interstate because of low transmission fluid. This issue might also occur because of a bad transmission sensor or overdrive sensor.
usually it is the overdrive solenoid, but can be the connector to it, input to the computer, or the computer.
I was told that it is the temp sensor. The car needs to be at 150 degrees. I am working on the same problem.
