Transmission questions


Recommended Posts

I just purchased an 88 Comanche; likely sold due to transmission problems.  I have been looking for any helpful information.  I believe that I likely have a Peugeot transmission, how difficult is it to swap for the AX15?  Are there kits?  Or is it simple replacements?

The AX15 is a direct bolt in trans.  However, there are two issues you need to research beforehand.

 

First, look for an AX15 from a 94+ XJ.  These came with the external slave cylinder.  You could get an earlier model and change the bellhousing and internals.

 

Second, the t-case that mates to the BA10 has a 21 spline input shaft.  The AX15 has a 23 spline output shafts.  So, you will need a matching t-case to go with AX15, or swap the input shaft on the t-case.

 

Additionally, as thejim42 mentioned, the crossmember for the AX15 is differnet from the BA10.

 

To recap:

 

1. Get a 94+ AX15 with bellhousing.

2. Get matching t-case (or change input shaft)

3. Get AX15 crossmember.

The information is quite useful.  I need to start looking and see what I can find; hopefully, I can find all I need soon.  The truck is a 4x4 and may just come back and ask more questions when it's time to get dirty.  Thank you much to all for your time and helpfulness.

Would the transmission for a '96 Cherokee do well?  I looked at "lowmileageparts.com" for transmissions, but they do not specify whether it is AX15.  They do describe "manual transmission, 4X4, 6 cyl" and not much else, which describes what I have.  The pictures show the transmission with bell and all, but I'll need to call to be assured that it is as it shows.  Additionally, it shows a smaller part, which looks like a transfer case to me. 

 

How difficult would it be to change the input shaft?  I figure that I can get a crossmember at some yunkyard. 

 

Any information would be most useful.

 

Thank you in advance.
