sup ya'll, 97 neon sohc, auto tranny. installed good used tranny, after bellhousing bolts tightend up, nothing will turn. cant turn crank at pully now. before they were tightend it turned fine. what is the problem? it acts like it's either too tight, or not lined up right, but i dont knowhow. any help would be awesome....

 

Sounds like the converter is not lined up and in all the way so its not in as far as it should be.
Did ya notice it was a little hard to tighten the bell housing bolts down?
