89 AX15 swap into 88 4.0

[johnny quest]

ok so I'm attempting to mate an 89 ax15 to an 88 4.0 that used to be backed by a Pukegoat. I know that i'll need to get the bushing/bearing from a 73 cj5 with a 304 v8, but what else should i need that didn't come in the transmission to begin with?? I'm hoping that since the parts are only one year different, then not much, if anything changed, and its just a matter of bolting part A to part B, and tying up the loose ends. I have the correct np231 that came with the ax15, so no issue with spline counts, and i have the correct length driveshafts. I've read over countless threads, and i've while i've picked up some stuff, i think alot of it just confused me more...

 

edit: will i need a new pedal assembly for the clutch??

ok so after MORE reading, i guess i won't need the 73 cj5 bearing/bushing. the ax15 has a new slave that the PO put in; should i get the ax15 master as well?? or will the BA10 master work??

Correct, the CJ bushing is only for putting a 92+ AX-15 behind an 87-91 4.0. You won't need it.

 

You will need the AX-15 trans crossmember and trans mount.

 

If it's 4wd, you'll need the AX-15 4wd shift linkages.

 

Your current clutch master cylinder and pedals will work. Those weren't changed.

I'm assuming you've got the AX-15 crossmember? AX-15 trans mount? AX-15 bellhousing? AX-15 shifter?

assuming you can't find or have the transfer case linkage here is a link to make it http://www.comancheclub.com/forums/view ... 2702&hilit

i put the 96 in mine and had to put all new master, line and slave in to make it work. I'm not sure on the 89's

[Pete M]

96 would have been an external slave and used different parts than the internal slaves (94 and earlier). :thumbsup:

[johnny quest]

so the split for parts is 94 down and 95 up??

[Pete M]

sorta. I think it's halfway through 94. or maybe it was 95. my memory sucks and the cutoff is less clean than you might think (like most of the changes in our Jeeps).

 

 

also, I adapted my 99 external slave line to my original 88 master using a pressure fitting from the hardware store.

[cweemanrun]

ya it was the only trans i could get my hands on and getting the clutch parts was dealer only and it was complete assembled. was alot of money to think i paid 300 for the kit

So, my mechanic has finished the 95-Ax15 swap in for me, but it has been a couple of years since he has done one, do I need a 95 MC or is my 88 MC up to the task.

TIA

the 95 is no more powerful than the 88.
