I'll check with him. My brother in law checked with their "godfather" and he said a 2000-2002 trooper or axiom trans would work with the computer on this one. Otherwise it would be rewiring sensors. He said that there isn't any difference in the 2wd and 4wd transmissions other than one has an output shaft and the other has a cover plate with the output shaft removed. So we are on the hunt for either a 2wd or 4wd trans OR some way to find the bum part of the trans. I will start checking around shortly.
