89 YJ AX-15 transmission?

Hi Guys.


I know it probably has been asked, and I did do a search, but I couldn't find exactly what I was looking for.

I have an 89 wranger with the 4.2 and the AX-15 tranny.

I am looking for a direct replacement and am wondering what other vehicles/years I could look for this.

I found one in a '94 Cherokee Sport. (4X4) Will this work?

Thanks for your help.

When using a non YJ AX-15 in a YJ, the NP231 transfer case will hit the skid plate because the T-case is "clocked" 10 degrees lower on the driver side, so you'll need to address the location of the mounting holes at the rear of the AX-15.

This pic & explanation were stolen by me from fellow JF member "idaholtby", he posted this in another thread a while back.

The transfer case clocking is determined by the mounting holes on the output of the transmission. Simply redrill the holes to raise the transfer case to the YJ height. In this pic, the holes on the right on each tab are the newly drilled holes that the YJ configuration requires to clear the skid plate.

Yes it will work, you will either have to notch your skid plate or reclock the transfer case though. The holes for the transfer case in the back of the tranny are slighty different between the Wranglet and Cherokee. The mod is easy to perform and Mean Max has pics to show you what to do to reclock the transfer caase back to it's stock lication.

But I doubt I'll be feeling much of anything later on...........it's 40 degrees outside, my YJ has no top or doors, and I have a 30 mile drive home when I get off of work at midnight......

I could claim machismo, but I think the blame rests squarely on STUPID.

At least it's moving! Thanks for the quick replies. I don't have the tools to drill those holes though. So it looks like I'm still on the hunt for a YJ AX-15. Will any year (YJ) be a direct bolt in, or am I going to run into the same problems?

It's just soft aluminum, a hand drill will work fine.

But as for compatibilty, YJ AX-15 models from late '89 through '93 are the same.

"94-'95 are only slightly different & can easily be adapted to fit with your OE parts, or you can swap your '89 to an external slave cylinder which would be the best case scenario.

You also have the option of notching the skid plate all you need for that is a hack saw and they are cheap if you need to buy one. The notch is on the drivers side rear of the skid.
When you look under there you will see a hole in the skid near the drivers side rear of the skid just below the lowest part of the xfer case. You just cut that area out to give the case some more room. Took me 10 mins to figure it out.

I understand that I'm reviving an old thread. I just had to use a Cherokee trans in my YJ. Some fellas in /f12 were a big help. I YouTubed the tail housing swap between the XJ & YJ trans. For the people that don't have the YJ trans to swap the tail to the XJ, I also demo'ed how to establish the drill pattern. Even whipped up a CAD drawing for a template. I just wanted to drop this in hopes that it helps someone.



1991 Jeep Wrangler YJ, <-- My Jeep is a pickpocket!!
1984 Mustang GT Top 5-Speed <-- Running soon hopefully
