OE transmission (Peugeot BA 10/5) or AX15 upgraded transmission?

I would start collecting the pieces for an AX15 swap. Even if it's just a clutch issue, I couldn't justify pulling a Peugeot & then reinstalling it.

What are the key reasons for going new AX15 vs OE rebuild?

Are there any clutch issues that follow this type of tranny problem ?

Big Mahalo for your help !

The Peugeot BA 10/5 tranny you have is a notoriously weak/poor transmission. Jeep dumped it approx Oct 89 in favor of the AX 15 early version which had the 0.590" pilot snout. (newer version AX 15 came with the 0.750" pilot snout).
Rebuild parts for the BA are hideously expensive, and you still have a Krappytranny. The AX 15 is cheap, durable, and easy to rebuild and the parts are much much cheaper. Full rebuild kit is about $300 on ebay.
To make sure what tranny you have, look at it from underneath. If it bolts together side to side down the long axis like a suitcase, it's a Peugeot. If it bolts together front to back, it's the AX 15.
When you are describing non-reassuring sounds that come only in certain gears, it does sound more like internal/transmission issues rather than just simple clutch issues. You can start shopping for parts (Craigslist) and drive what you got til it grenades, then replace everything: clutch/transmission.

Shoots.

You need the AX 15, and since you're going that route, get the stuff to convert from internal to external clutch slave. Links coming. I am having to assume you have a 6 cylinder, and not the 4 cylinder. I can't get that out of your profile. (cough)

HERE's one conversion thread.

And here's another option.

And how to convert from internal slave to External Slave.

If you get an early model AX 15, it will have the small diameter pilot snout and you won't have to mess with figuring out how to come up with a different kine pilot bearing.

Shoots.

Anyone know if a transmission from an 89 Comanche would work with my 88 YJ?

I live on an island where parts are limited and shipping doubles the price of everything

The shifter may be a bit different on an MJ than on a YJ. Since the MJ you mention to be an 89, then it should not have the Peugeot BA tranny, and so long as it is from a 6 cylinder, it should bolt to your engine. The input snout should be 0.590" which should match yours. I am uncertain as to how the T-case will be clocked though. We know that on the XJ it is clocked 10 degrees down from the way it is clocked on the YJ, but that is remedied by re-drilling the 6 mount holes on the rear case. If you have this MJ AX15 trans sitting on the bench rather than still in the MJ, then send some photos of the back end of the tranny so I can see the clocking and I can tell you if it is clocked correctly for the YJ already.

I check Craigslist for Jeep parts every day. I have noticed recently that there have been more AX 15 trannies available on Maui than on Oahu or the BI. Have you checked Craigslist.

One other thought, do you have the NP231 T case on your YJ? Supposedly the NP207 was only used in 1987 on the Wrangler, but you should check to make sure that your Jeep isn't "special." You need to count the splines on the output shaft of your tranny and make sure they match the number of splines on the output shaft of the AX15. This could mean you need to get the T case as well. Someone will need to tell me if I'm correct or not, but I think you may have an NP207 T case which would require 21 spline, and the MJ AX15 will have 23. Even if you don't have the 207, the BA had 21 splines I seem to recall, so make sure you check closely.

Make sure you read those conversion threads I linked til you practically have them memorized. This will prevent a ton of surprises. Jeeps are just full of surprises........

I bought all my adapters for my NV3550 conversion in my 88 from Advanced Adapters. They sell a kit and have great customer support if you have any install questions.
