okay, my stock transfercase crapped out in my 1994 jeep wrangler (NP231), would a NP231 off of an automatic match up to my manual transmission (AX15) and if it does what year models or does it matter?? my jeep has a straight 6 and i will be getting the t-case off a cherokee with a 6, and my other question is.... will the automatic transmission out of that cherokee match up to my engine, because if it does, i am going to get the tranny and t- ase and do an automatic swap, if you know anything about any of this, please let me know
