Hey guys... I found a cheap turbo 400 trans. It looks like it has the "long yoke" on it.... from an Old Bonneville, I'm told. Would this work in my Skylark or do I need a short one? (I'm assuming I'd have to get a custom drive shaft?) Thanks!
You have to change to tailshaft to a short one. But your going to have to get a new driveshaft anyways.
So the short shaft is mandatory, even though I'll need a custom/different drive shaft anyways? It sounds like you can swap the short/long shafts, but you need to tear the tranny apart and replace the tailhousing as well? Its going to get rebuilt anyways, so it wouldn't be a big deal- assuming I could find a tailshaft and housing.
you can fit a long shaft in a 65 you just have to get the correct length driveshaft made. the down side is that with the tranny output shaft being closer to the rear you end up with a sharper angle on the universal joints. ideal way is to use a short shaft.
I have installed long T-400s in several a body GMs Buicks Olds and Pont. Never had a problem. Drive shaft needs to be shortened of course. Bob H.
I just installed a long tail in my 1970 Riviera. I found a fresh rebuilt 400 that was going in a gto. I had to get the drive shaft shortened and I had to fab a crossmember.
