manual to auto swap question

just finished a swap from a 2WD manual to a 4WD auto (AX-15 to AW4).

i would recocmmend just pulling the whole transmission/transfer case assembly and buying another one already assembled. that way you don't have to worry about spline counts, adapters, or sensors.

if its relatively low milage, you should be able to sell the manual 4WD no problem.
 
Depends what year donor for the AW4. I think it was 91 that the AW4 switched to 23-spline? A 99 AW4 bolted right up in place of the AX15 in my 89 MJ. I did run into the problem that in 98 (?) there were a few changes to the AW4 sensors that I had to work around (added front speed snensor and rear sensor changed pulses/rev).
