been down that road as what i was told no unless you do some welding and the ax5 trans will not hold up to a 4.0(light duty) the 4.0's have a ax 15 (heavy duty) and you need to transfer all computer stuff the best way if it was my choice is to rebuild what you got or buy a 4.0 jeep all set p.s unless you have a lot of money do a v8 conversion BUT it is costly my 2ct's
