Allisop
 

My brother and I are considering getting an Allison tranny put into his 95 Dodge diesel currently running with a 2wd auto. He is wanting to mod his truck a good bit and would prefer an Allison over beefing and rebuilding his current tranny. I am told if I get an adapter from a 4-bt that had a t/h 400 with the flex-plate, crank hub/spacer, wavey ring, starter, and all the bolts, the GM allison (from a duramax or 8.1 gas engine) will bolt right up,. But I am also told he'l have the GM "tilt" to the engine, but I am also told it wont be an issue. I am pretty sure I get an allison 1000 or 2400 from a freightliner or school bus it should have an SAE#3 bell housing like he needs to fit that adapter. Any ideas, bombers?
