The fact that i do alot of diesel modding/tuning and engine swaps (cummins,dmax and LS's) is the only reason I chimed in.. I never intended to chapp anyones ass.. just trying to enlighten someones questionI personally wouldnt try to reinvent the wheel. Id stick whatever came behind the Duramax in there. The 4L80E (TH400R) is a very strong and capable transmission indeed. But hey, Im sure YOU have tons of experience with motor swaps and diesel performance... (spoken like a true copycat condescending fart hole).
