Tonight I'm going to (hopefully) buy an 89XJ. I want to be sure it's got the AX trans, and not the BA.
Can anyone give clear instructions on how I would confirm without a doubt that it's indeed an AX?

I'm not 100% sure if this applies to XJ's, but the YJ's went from the BA to AX in March of 89 so you might check the build date.
Edit: look at how the case splits.
AX15: Crossways, like the Tcase.
BA10: Lengthwise, front to back

Nice, that's really simple! I just looked at my trans, its just a hair offset, guitar the split is from front to back.
Where will the split be on the AX?
I mean, if its exactly like nine I know its not an AX. But I want to be clear on this...

My only concern is the difference between the internal and external slave AX...

Btw after I did the AX conversion I was happy. It shifts nice and smooth now. No grinding or anything. Clutch pedal is more stiff and center.
One of the best upgrades I've done.

If there's a split line that runs front-to-back (case would split into a left half and right half,) it's the BA-10. The AX-15 is divided crosswise into a centre plate, a front housing, and a rear housing.
The AX-15 and NV3550 both readily replace the BA-10 with minimal effort.

Easy enough - slide under and check the bottom of the case.

But for now, I will send you as many
as I can from the interweb! LolMy new challenge, changing over from internal to external slave...
Did a Google search for images, and found this thread: http://www.jeepforum.com/forum/f19/y...ite-up-312203/
Novak also has a good picture of the AX-15, but no real detailed picture of the AX-15.
To help with visualisation, here's an exploded view of the BA-10/5 - http://cdn.liveoffroad.com/images/Pe...ansmission.jpg
And of the AX-15 - http://www.jeep4x4center.com/jeep-tr...sion-large.jpg
