I just got back from picking this bad boy up... It's an AX-15 from a '96 XJ that the seller claims was rebuilt within the last year or so. No bellhousing unfortunately, but I did get the crossmember and a few various other parts. All for $175. This is the start of my '86 2.5L/AX-4 to 4.0L/AX-15 swap. I posted this in MJ tech because I need to clarify some things and I'm hoping y'all can help me out. First, I know I need to find a bellhousing, shift fork, external slave and all that stuff. The thing I'm not sure of is if a NP231 from an '88 or '90 XJ will bolt to this transmission since I'm not sure what each of the spline counts are for an '88, '90 and '96 transfer case. So, does anyone here know for sure? Also, the rear driveshaft is going to be concerning. What do I need to know about that? I should also note that I'm thinking about getting a C8.25 and welding on SUA leaf perches. Also would like to know what gears would work best with an 4.0L/AX-15 combo. I know that stock used 3.07s commonly. I want to make this the most fuel efficient Jeep I can make it. At this moment, I have no intention of lifting or running larger that 215 tires. Also, any writeups on the subject are greatly appreciated. I should also note that I am pulling the engine, computer and all from a '90 XJ with an automatic transmission. Is that going to cause any issues?
