start date for using the AX-15

[Pete M]

this came up on the faceybook and apparently there are a couple websites out there in internet land that list it as mid 88 (fix your site Novak!), but I looked it up and it is for sure mid 89 model year for MJs and XJs.  March 10th to be precise.   all hail the factory parts manual!

I had an 89 MJ built late 88 it still had the Peogot trans. The build sheet stated Heavy duty transmission.

Thats interesting, according to that list ALL 89-later 4.0L 2wd MJ's had an AX-15.

Missed it by Thaaaattt much!  My build date is March 6.  108 k miles on it.  When I can I expect it to explode?

Never, if you're gentle on it.

 

Some BA-10s have 300k miles on them without a rebuild. Some blew up young. I'm betting the difference was between the seat and pedals.

 

With that being said, if the transmission can't handle being driven roughly, it's really not suited to the application anyway. But don't think your trans is going to blow up any day now unless you're doing burnouts or are doing heavy wheeling.

Right now I'm keeping it original and just driving it.  But if it ever let's go all bets are off including a 4wd conversion.  I do plan to get it muddy but nothing hard core like Moab offers.

BA10/5 are meant for on road driving, no heavy load, no heavy hauling, no jackrabbit starts, no powershifting, no gear floating... perfect for granma...

 

from what i have read, worn synchos and case stretching are the common failures, the first due not shifting gears properly, the second.. mm the case is too weak?

 

what was AMC thinking...

Actually... we can blame Peugeot for their transmission. Remember who AMC was partnered with.

I may as well kiss it good bye then. I float gears all the time. And launch hard.

it may blow any time
