I have a 1997 dodge cummins turbo diesel automatic and my transmission just started to give me trouble. everytime i go around a corner in fourth gear it goes into neutral and after i get around the corner it will go back into fourth. And when i am excelerating i will get up to 2,000 rpm and it will go into neutral or something.

 

It sounds like it might be low on fluid. When ours gets low it acts up like that sometimes.
