Engine is the non-HO version of the 4.0L (Renix). Auto tranny is the same AW4 that was used in all years with the 4.0L engine. Transfer case could be 231 (Command-Trac) or 242 (Selec-Trac).

IMHO the Renix is more reliable than the HO -- it was designed by AMC rather than Chrysler. Most of Chrysler's "improvements" were intended to reduce manufacturing costs, not to make the vehicle better for you and me.

What Eagle says, plus:

The AW4 and whatever case it has will be 21 splines and those cases have a mechanical speedometer output.

I can't vouch for the reliability of the HO periphials, but the Renix system is super easy to troubleshoot & repair. I've had (at one time or another) 5 Renix 4.0s and 4/5 ran really good pretty much all the time.
