Started working on this project tonight. Dropped the bulky t-case out of my '94 SR in the hopes that I could get a NP231 transfer case to bolt up in its place.
The NP231 can be found in many Jeeps (especially Wranglers), and was also found behind the AW4 in some applications. The NP231 features a low range of 2.72:1 versus the stock Mitsu gearing of 1.90:1.
This is where things get interesting...
The Mitsu V4AW3 is built by Aisin Warner and variations of this transmission can be found in many different makes and models of vehicles. The one I paid attention to is the Jeep version which is the AW4.
I counted the splines on the tail shaft of my tranny and it appears to be a 23 spline unit just like the AW4. I bolted the tail housing from an AW4 up to my V4AW3.
Tomorrow night I will try to see if the NP231 will jive with everything else...
