I blew the Y1 in my CRX a while back and I'm finally getting around to replacing the transmission. It should be easy, but for some reason I can't get the damn thing to mate with the motor for some reason. I can tell its a b-series cable tranny for sure, and I've heard they're all compatable, so it should fit right? (The guy I got it from couldn't remember what it came off of and it was only $30...I couldn't complain much). I'm only going to use it until I can rebuild my b16 tranny and use that. Anyway, I've got the thing hanging from ropes in my garage and it looks like its lining up correctly. I have no clue why I can't get the damn shaft into the hole in the motor. Is there any chance that the input shaft is a different diameter?
