Help ..904 has died 4 times !

sounds like to me you have had two guys that are clueless doing work on your trans. also sounds like there is a mis match of parts all over that thing.. for me the best thing to do is to find another 904 ( preferably) 70-up so you know it will work on your 360 and start over.

the guy that says a 904 doesn't belong behind a 360 is an idiot.
