just put a 5sp tranny into my auto, i went to spin the driveshaft to put the bolts in the other side and it wouldnt budge, tried shifting it into neutral (without a shifter installed, i tried using all kinds of things to shift it but it doesnt shift) but even if its in gear it should move a little either way, but instead it acts like somethings seized or stuck, motor turned fine when the tranny was unbolted and it ran good with the auto in it, i had the tranny apart and it shifted then
but now nothings moving
im guessing trannys bad but like i said i had it apart and it shifted then, only thing wrong with the tranny was the end tip of a shift fork was broken off
