jeepsteeve i think you got it on the nose. The crapper auto pulls hard at idle i think the tourque conveter may be the culpret is there any way to know this is my problem. I do have the stepper motor but i would like to get rid of half the wires and emmissions crud if i could. The tranny also leaks, i have already replaced cooling lines, which were obviously no good, and have also done the filter and gasket.

is there an easier way to fix this than swapping in a cummins 4bt and an nv4500, hhhhmmmmmmmmmmm
