ax15 out of a 1991 dakota into 1988 MJ?

[nameless]

sorry this is my first post, just in need of some help, after i post here i'll start my build thread

 

 

 

I have an 1988 MJ 4.0L with the 5 speed manuel ax-15

 

i got this 3 days ago and the tranny is blown, i found a steal on a ax-15 from a 1991 Dakota V6 and the guy was running it in his 1995 Wrangler

 

 

 

i'm not to sure on the spline counts but should this work as a direct swap? both are chrysler, just wondering on the splines and everything else hah

 

thanks, Austin

The trans itself will be the same, but you'll need a 4.0 bellhousing.

Oh, you didn't mention 4wd or not... unless that's what you mean by spline counts.

 

But no, the T-case behind your BA 10/5 will not bolt up to an AX-15. BA 10/5 is 21 spline output, AX-15 is 23 spline. The transfer case outputs will be the same though, for the driveshaft.

yes 4wd

 

 

 

i'm pretty sure i'm running an ax15 right now?

 

 

 

i'm confused on what a BA 10/5 is???

 

if i am running an ax15 will it match up? what will and what will not?

 

sorry i'm confused hah, just getting into this jeep thing

[Geonovast]

Nope... from 87-mid 89 the 4.0 got a Peugeot BA 10/5 5 speed transmission. It's a piece of junk, better served as a boat anchor. If you do have an AX-15 now, some PO swapped it in.

 

Here's how you can tell the difference : viewtopic.php?f=9&t=11699

 

The fact that you said the tranny is shot makes me think you have the BA 10/5. You have to try pretty hard to fry an AX-15.

if the guy was running it in his wrangler, does that bellhousing come with it?

[nameless]

looks like the BA10/5 or whatever it is then... damn

 

 

 

thank you guys, what would it take to convert it over to the ax15? just a new t-case?

 

direct bolt in?

[terrawombat]

If the guy has it working in his '95 Wrangler and is going to sell you the transmission plus the bellhousing, it'll be a direct bolt in. You'll need to find a transfer case with the 23-spline input shaft, though.

You'll need an XJ/MJ AX-15 trans mount and crossmember.(I just recently learned about the crossmember differences.)

DOH! I knew I forgot something :)

I think the only other thing you'll need is the 79 304 CJ pilot bushing.
