How much power can the AX-15 handle? I have an '89 305 TBI from a Firebird. Can the ax-15 hanld it? the 305 should have maybe 10% more power and 20% more torque than a H.O. 4.0L. Should I just look for a 5 speed with transfer case out of a fullsize chevy to bolt on to it? what should I look for? My jeep is for daily driving and weekend hunting trips.

Yes it will work.

I've been using an AX-15 w/ a Chevy 350/33" tires/3.73 r&p for a few years now in my YJ. I've stomped the petal hard in more than many situations and no signs of damage. One thing to consider though is the lower your r&p gears are, the less stress the engine will exert on the tranny (ie: 3.08 will be harsher on the tranny than 4.10 because it's a little harder to get the tires turning w/ higher gears).

And if it's just a daily driver w/ occasional offroad trips (as is mine), I'd say go for it.

Y'all have guts! I heard so much stuff about the ax15 not able to hold up to hp..... I got scared and got rid of mine when I put
my chevy in. Now have a TH350 with an adv adapt kit linking it to the np231. Runs stong, but hey, if the ax15 works. I really
just wanted an auto, better for towing toys (boats, 4wheelers, ...)

might be the best time to bite the bullet.
Only have to buy one adaptor for trans to tranfercase.
Just a thought.
