If you are going to do the auto, you will need the wiring harness and tranny controller as well. You could be in for A LOT of work doing that swap in an '86.

 

The AX-15 would be the easiest swap for a manual. It would be best to find one of like year model, but most any will work...just some take a little more effort than others, especially where the pilot bushing/bearing is concerned. There are at least 2-3 recent threads about just that if you do a little searching.

thanks brent ,i stripped a 91 xj for all the parts ,took all the harnesses out ,fuse block ,the whole work,s ,to put in mj ,will that work?and if you don't mind me asking,are you the brent that put leafs in the front of his mj?thats what i am gonna try to do,any suggestion?and thanks for your help ,need all the help i can get. :bowdown:

I have not done a AW4 swap personally. I am not sure about compatibility from a 4.0L to a 2.5L harness unless you are changing all of the wiring and not just the tranny harness. That will likely take a little more research. I know it's not a terribly hard thing to do if you already have a 4.0L though.

 

If you go the AX-15 direction, try to find one that is '91+ to match your motor. It will make it much easier to get a match on the pilot.

 

No...I have not done the leaf conversion on mine ;) .

Auto or manual is really more of a personal preference (as long as you've got the right gearing). Me, I like manual transmissions.... for everything. :D We once owned a minivan with a manual in it.

[parker454]

i like a manual too,will everything work with 410 gears 35 inch tires.and a ax 15? and thanks for your help. :chillin:

[Pete M]

4.0 is the low end of what will work. 4.56 or 4.88 would be better with 35s.

I love my 4.56s on 35's but if I could do it over...Definitely would go with the 4.88s for 35 inch tires

[parker454]
