    Post I Need Help with Transmission/Transfer Case Issues

    The Victim: '97 4.0 Wrangler automatic

    The situation: Transmission will not go into Park drive or reverse, (like the transfer case is disengaged into neutral)

    How it happened: Got stuck in the mud, as I was trying to get out the transfer case would pop out of 4w H and L into neutral. I'd let it cool, then try again. after digging a trench into the ground, I had a friend pull me out (embarrassing but eh). and as that was happening it stopped working. (check out the vid to see if you can tell what happened: http://s842.photobucket.com/albums/z...rent=055-1.flv )

    What we've done: we drained the transfer case fluid, no metal flakes Checked the chain still attached and spins when I move the drive shafts, and took the pan off the bottom of the transmission, once again no metal flakes.

    So far from Friends and family, we believe it could be a shift linkage problem or an output shaft

    Does anyone have any other ideas? I've never worked on trannies and i don't want to take it to a mechanic to get looked at, get robbed, and then find out I just needed to do something simple.

    Thanks for your help

    It is possible that you got enough mud, stick, etc. packed up around the linkages to interfere with shifting them. Sometimes (I've seen it happen) it is possible to twist your frame enough to tweak the transfer case linkage since it is connected to the tub.
    One more thing I have to ask since I do not want to make any assumptions....you stated that "when I move the drive shafts" You did actually disconnect the drive shafts to do this, yes? If the answer is no, then you may have broken an axle shaft or fragged a differential.
    I would start be making sure all of the linkages were clear and free.
    Let us know what you find.

    .

    This ^^^^^ Especially if you have a body lift. Even without one, The T-case linkage is notorious for popping out of it's bushing/bracket.

    Check the linkages like treefrog said, and while your under there, try and shift the T-case (proably need a bar or big screwdriver)

    The shift handle for the Tcase is mounted to a 'rod', that mounts one end on the tranny and one end on the tub. This part pops out a lot.

    government knows that it cannot rule over the people by force.
    Those who stand in defiance of unconstitutional laws
    do so out of duty, honor, oath and love of country.

    When I twisted the Shafts the jeep moved back and forth so I dont think any of my diffs or axles are busted
