Hello all, I am a newbie here and am looking for some information and am having a hard time finding a forum that matches my issue.
I have a couple HMMWV (Humvees) and I have done a Duramax/Allison1000 conversion on one, I am looking to get rid of the lossy and under geared TH400 in #2, the low 1:1 gear ratio and non lockup is really a problem with running high RPM trying to keep up with #1 (DuraVee)
So I just picked up a 6L90E with transfer case (would have preferred a 6L80E) and am wondering if anyone can enlighten me as to what it will take to mate it to the 6.2L, as far as I have read the bell housing should bolt up so I am mainly concerned about the torque converter, not concerned about the electronics or other issue at this time just the engine/transmission connection. I do have the correct flex plate for a 700R4 (was in the works before I stumbled onto the 6L) and of coarse the originalTH400 which is different.
