    i borrowed my buddy's 82 jimmy (automatic). I was driving, slowed down and then when i went to go accelerate the truck again, it wouldn't go anywhere. I turned the truck off and then started it again, same thing happened. the truck will run fine. i can put it into a gear it just wont engage( it will be in drive and i press the pedal and the engine revs). the tanny fluid is fine and the linkages are fine. i tried to put the truck back in park and it makes something like a grinding sound. the last time it happened i put it into 4 lo and then back into 2hi, then put it back in drive and it worked. the tcase was in 2 hi all the times this happened. Is his tranny dead or tranny or do you guys have any other suggestions?

    sounds like the planetary in the transfer case went out. The Transmission is spinning and that is why it grinds when you put it in park, Turn the motor off to put it in park to solve that. But usually when a planatary goes, it sounds like a grenade went off under the truck. sounds like the tranny is still turning though, could of broke the chain also in the t case, that might not make as much noise. Jack the back wheels up, and turn the drive shaft, with the tranny in park, drive, whatever, if the drive shaft still turn while it is in gear then it is probably the t case. lol

    did the t case slip out of gear? you said something about putting it in 4 high then 2 high and it working, could be a shift fork problem in the tcase.

    You described my truck, I have yet to get around to adjuting it ( I just use 4 lo or 2 hi anyways ). But I did remove floor shift cover and boot, removed 4 hi stop plate and when shifting without the stop plate the shifter grabbed each gear enough to stop grinding. It is a threaded rod with a jam nut on each side of it to adjust on 80's trucks with np208's /forums/images/graemlins/k5.gif
