trans problem 84 cherokee

[rbarse27]

drives great. come to stop I hear the gears turning and it wont go nowhere. put in park and it grinds to a stop.then it wont catch the gears (R or D), put it in 4L and moves.put it back in 2 wheel and some thing, runs until I come to a stop.sometimes I can put it in 1-2 and it will work with "manual" shifting. please help with ideas to fix

You really have to drop the pan first. If you have metal slivers/shavings in the pan/fluid/magnet the trans is shot. This is not the metal dust on the magnet.
