ES,

The tranny you want if its from a Mitsu is the V4AW3, the NP231 & NP 242 bolt up to it but you have to swap in a tailhousing from a Jeep Cherokee that has the AW4 tranny (Jeeps version of the V4AW3).

I have done this recently using a Behemoth Strong Box mated to an NP 242.

You might be better sourcing a tranny out of a Gen 2.5 Montero or a Jeep Cherokee.

heres my writeup.
