I'll try and make this quick. I have a '91 XJ with a 4.0L and aw4 tranny, and a '88 with a 4.0L and a Manual. I want to swap the '91 Motor and tranny into the '88 but my Mechanic is telling me that we can swap the motor but not the tranny because the computer will through a check engine light on. He is telling me that the computer will not recognize the new tranny. Is there any truth in what he is saying.
From what I understand:
#1- ECM's will NOT direct swap. but the only sensor the ECM monitors is the VSS, and that can be tricked somehow.
#2- Every part on my 88 should fit directly onto the 92 HO motor. so it should be an easy swap .
But I still don't know if I can use the AX4 in the '88, and if I can how.
- any help would be greatly appreciated.
Thanks
