Peugeot BA 10/5 to AX-15

Hi, I'm trying to get ready to start building my 87' Comanche.
And the first thing that I want to do is rid the mj of the BA10/5.

I have a new style ax-15 ready to go in but am wondering if the np231AMC will have the right spline count to go on it.
Thanks,
CJ

Ive heard the ba 10 trans has a 21 spline like the ax 5 behind the 4 cylinders. Ax15 has 23 splines. I was told you can swap the input shaft on the transfercase (231) from 4 cylinder to 6 cylinder by replacing that shaft. I ve never done it. I hope this helps. Other thing I heard is 231 from manual trans wont work on automatic. So if you find a ax5 231 transfercase, swap input with 23 splines, then your on your way.if you look in salvage yard you may get lucky and find ax15 cherokee. Snag you a t-case from that.good luck bro

The spline count info is correct. The Peugeot has a 21 spline output shaft, while the AX-15 has a 23 spline output shaft.

The input shaft can be swapped, but make sure the 23 spline input shaft must be the same "cut" version as transfer case it is going into. There was a slight change made in the cut of the gears in '94, so you'll need to make sure that both the donor part & the transfer case are on the same side of the cut range.
