OK I've got a C4 that I bought used from a dude at the world ford challenge 3 years ago. Finally putting it in the car. I have no idea what is in it, he was from the south and said it was built, its got the manual rev VB, a brake, I can see the PA servo on the outside. Well the problem is (at least I think this is a problem) when I bolt up the bell housing, the input shaft won't turn and the output shaft won't turn. When I pull the bell housing off everything spins freely. I noticed that the pump (I think it is the pump) has to locate into the tranny case and if that goes in a little crooked it doesn't turn. So I got it in there flat and when I bolted up the bell, I could turn the output one way really easily, but it won't turn the other way. The other thing that I noticed is there is big input shaft and a little input shaft inside of the big input shaft. The little input shaft spins, the big one doesn't, at all. What is going on here. HELP!!!!!!!
