You can go with an AW4 from a 2WD Jeep Cherokee with 4.0L, but you need to make some changes. Alternatively, a GM 4L80 with an AMC Scattershield conversion (you grind the Chev bell off and it bolts to the front pump of the trans) and manual valve body will take just about anything. I found one when I was searching for a Jeep trans to replace my TH400 for my upcoming tow truck M715.
