    Put it back on and adjust it. A easy way is to push the "d" shaped button and let it retract in. Then go and mash the throttle and it will ratchet out.
    This will get it close enough to where it wont fry it.

    If it still doesnt work then it kind of sounds like your TC went out.

    Can you move the cable back and forth?? The cable should have spring to it.

    not to hi-jack but when you say that you mean you pull the cable from teh top and release it and it pops back quickly? cuz mine takes a while to retract back in...

    It should be quick. It needs to move with the throttle linkage so if it goes in slow it would come off the stud when the linkage retracts.

    As long as it moves with the throttle linkage then there isnt a worry since thats what its supposed to do.

    Did you try setting the TV cable?

    10 miles is enough to burn up the tranny. that controls the pressure to everything, if its no hooked its getting minimum pressure and allowing the clutchs to slip. a few minutes of that and there is no clutch material left.

    if it came unhooked, check to see if the clip is not broken. also if the TV cable is not snapping back when pulled all the way out, either its unhooked inside the tranny, or you need a new cable.

    I'm surprised no one has said, check your fluid. Make sure the engine is running and tranny is in park.

    x2, just make sure its hooked up inside the tranny.
    its possible that you burnt it up, but try it and see.

    i am goin to try that when i get off work tomrrow....if that doesnt fix it, what would be wrong internally w/ the tranny...that is what would be "burnt up", is that the pump, or the clutches or everything inside just curious what actually gets messed up....thanks also...just to reemphasize, if i dont drive it for a while and i hop in and start it a try to go it will drive about 1/4 mile then start slipping and not go anywhere is this still the cable...also i dropped the pan today and there is some small metal roller-bearing type looking pieces...what the hell does that mean....

    if you found roller bearing looking things, you killed either sprag (roller clutch). tranny is toast, time to rebuild.
