904 rebuild

Well it started to be a interesting transmission thread for the first few post then it turned into a weather discussion. When it turns back into a transmission thread I'd be glad to give any help I can. I've only prebuilt one 904 and it was as easy as falling off the couch.
I have looked through some previous posts on the 904s and looked at some related parts links. Want to make sure I don't have to rebuild if I add nitrous down the road build in some wiggle room for more power
