Was stuck in my 92 Jeep Wrangler when trying to rock it out the shifter became stuck in reverse position however the truck will not move

Try slowly moving the vehicle in reverse and trying to shift back to 2 wd.....do not force.....shift fork damage could occur.....Try slowly moving the vehicle forward as well....Move the shifter firmly but don't force it.......Make sure the hub locks are in the free position too...........

Your shifter may have come loose and slipped out of position. This video may help.

on top of transmission you can see the shifter cable remove it from lever. Try to move lever freely try to move the shifter if it stuck again
could be cable or transmission internal
hope it helps

The shifter cable has broken more than likely ,Find the shift shaft on the transmission,,block the wheels and remove the shift cable from the shift shaft,put the gear shift in park,then shift the shift shaft in park,then it will start,Then of course you will have to replace the shift cable.

try pushing the knob down onto the shifter a little bit then try and shift. Sometimes if that knob is raised even a little bit it will be locked in park. Can't be 100% sure without seein it but worth a shot. Hope that helps you.

You have a broken shifter cable. The inner cable is broken though the casing may look fine.

this is caused by the steering wheel not locking, try moving the steering wheel one way and locking it, then it will start and you can shift it outta park.

Check for wear in the gear lever selector/gate mechanism.
It may have allowed the lever to select reverse, the 'jump' the lockout gate back to neutral position for selection of forward gears.
You may be able to de-select reverse if you access the lever directly at the gearbox case.

check the linkage from gearstick to gearbox

This sounds like the linkage could have fallen or broken off. Have someone move the 4wd shifter while you look under the vehicle.
