AX-15 Trans Question

I found an older ax-15 still mounted to a np24tc at a bone yard for 150. I checked the number on the trany and it appears to be out of a early or late 1980's wrangler. I cant be sure. It feels good and it seems the gears are good. My question is: Is there really any way to "check" that tranny. I would just keep the tc as a spare or whatever. I have a 94 2.5 that 5 gear is gone and the syncros in third are shot. Do I get the collar, clip and syncros for my ax-5 or go with the ax-15. Im I just band-aiding the ax-5. As always thanks alot the help.
ps. I do know for sure that it is out of a wrangler not anything else
again thanks

FYI your 4 banger is an AX-5. The swap can be made with a bell housing from a Dodge Dakota with the 2.5 in it.
The AX-5 is a weak tranny.
The AX-15 didn't appear in the Wrangler until very late '89 early '90. Before that it was the BA10/5. The spline count is different.
The BA10/5 and AX5 are both 21 spline, and the AX15 is 23, so if you replace the tranny with an AX15, you will need an NP231-J transfer case. Not the np207 or np231/amc. they are both 21 spline and will not work with the AX15.
Hope that helps.

interesting, I didn't think you could use an ax-15 behind a 2.5L. Good to know.

Yes, it is!

You can check the age of the transmission.

The AX-15 production date location is on the bottom where the tranny mount bolts up.


The "304" means '93 (the "3" part) and it was built in April (the "04" part) then the "8152" is the production code number.
