an ax-5 is a light duty tranny.(good for 4 bangers)the ax-15 is a medium duty tranny.other than a slightly different 1st gear,just strength is the only issue.if there were an easy way to put an ax-15 behind my four cylinder i would.

95 yj...
who ever said putting a spool in a daily driver was a bad idea was just jealous he had not tried it first...

The AX-15 was the standard transmission for 4.0L Wranglers from 1990-1998. The AX-5 was standard on 2.5L models and has a smaller input shaft. '99-present Wranglers come with the New Venture NV-3550, which I have been told is stronger than both the AX-5 and AX-15. The Cadillac trannies for YJ's are of course the NV-4500 and NV-5600, but then you're talking some serious $$$. Oh, but to have an NV-5600... (Mmmmmm - 6-speed w/ granny low 1st. droooolllll....)
