Converting ax5 to ax15

Daughter lost tranny in jeep again. Gotta love the ax5 . Bought ax15 with np231 transfer case and attached bell housing. This was out of 1999 Cherokee and cost was 325.00. Will the bell housing and tranny bolt up to the 4cylinder. I have seen post that I will need to get a dodge Dakota bell housing to mate up . Any advise is appreciated. Tranny came with the slave and line and appears to shift and engage in all gears easily.

No, will not bolt up. Yes, you need the Dakota bellhousing--the 4 cyl came with the AX 15, so you need to get that bell. Go back to the FAQ, etc and follow the links for more information. Second issue, you will find that the T case from the cherokee will be clocked down 10* lower than the wrangler. It will hit the skid plate unless you either clearance the skid plate, or simply re-clock your T case by redrilling the mount holes on the rear case of the AX 15. Threads on here covering that as well. I've posted up some stuff lately on this, just advanced search for re clock transfer case posts made by me. If that doesn't work, I'll link them to you.

I couldn't research and post links on my first reply as I was prairie dogging at the time so here they are.

Read thru these threads about clocking:

http://www.jeepforum.com/forum/f12/c...-case-1053744/

http://www.stu-offroad.com/engine/aw-4b/aw-4b-4.htm

And read thru this about converting AX 5 to AX 15 behind the 4 cylinder, it's from the FAQ
.

Interesting. Looks like you use an adapter plate between original bell and the AX15? Also allows for conversion to external slave at the same time? I'm going to have to read a bit about that later today.

It is advantageous to change to external slave.

Yes, basically a clever adapter plate between the AX5 bell housing and AX15 transmission that makes up for the difference in shaft length, and adjusts the bolt pattern to work. It's a great kit, and installs very easily. I didn't run it long - 2-3 months, and I had no issues with it.

I bought this kit with an AX15 while I was collecting parts for a 4.0L/AX15 swap. Later I also found a TJ Rubicon 4:1 transfer case at a very good price. When I got a bad leak in my front AX5 seal, I dropped in the AX15 and Rubicon 4:1 (an expensive and difficult way to fix an oil leak!) I ran the 2.5L with the AX15 for a short while, but have now started the 4.0L swap.

Yup, I have the advanced adapters kit. It's a little expensive, but not that much more than if you had sourced stuff yourself.

3 years later it's still serving me well!

Checked the aa adapter kit but there note says for 1994 or newer bell housing. Also out of stock. Have not checked locally for Dakota bell housing as yet, I did put TC and tranny together temporary like to prepare for a good cleaning and if I understand the clocking picture that was posted. My mounting holes appear to be in the correct position . Will research more once the smegma is off the two halves. Will shaft length be an issue with the bell change?. There was no mention of it in the thread posted in FAQ.

The link that I gave you above is for a used AA kit for sale in the forum classifieds. It includes the AX5 bell housing. Everything you need is in the kit

Thanks for the links and info regarding where to find parts needed. Started pulling things off and discovered broken bolts on tranny mount assy. And numerous other issues in regards to leaks. Will address those after conversion and she gets out of school. Did discover one of the helpers we use for digging and such grew up in his dads tranny shop. May recruit for help if needed in the future. Thanks, to all that posted info. Appreciate the help.

Pulled t case and drained tranny as suggested, fluid was light chocolate milk brown and signs of water. The tranny had been rebuilt 2 years ago and no signs of leaks . Shifter boot was Intact and to my knowledge the last trip to silver lake involved just sand and no puddle dives as Amelia calls it. Curious as to what else may cause water in tranny. Can the external electrical parts on the 91 t case swap with the 99 case, 91 has speedo cable and non electronic. It appears the two can be swapped, just trying to verify.

Not sure about converting the speedo, there are threads I have read concerning this, but since I haven't needed to do this personally, I just didn't retain the details. Not real sure how to search that one out, just keep your thread alive until the cognoscenti run across it and school us all. That's how the forum works.......
If you go deep when you get into water, it gets in the transmission, etc. Go into water, then change your fluids.
