Getting the Wheeling Fever
So I have a 91 YJ with the 2.5l and my 5spd manual went out. I am currently looking around for a replacement but I'm not sure if I need the AX-5 or the AX-15. Can anyone help me out?


Thanks


'91 YJ 2.5l, 5spd, lifted, 32's, and all of that other crap us rednecks put on our rigs

The 15 won't fit the lil engine you need the 5.

That is of course unless you are adventurous and want to "upgrade".....

Add a "4" and a couple of "0" and you get a 4500, as in NV4500.

With a heavy duty (1 ton) truck trany, you would never have to worry about the 5th gear going out...

But, reality sets in....

Definitely you have a AX-5 with 21 splines on the input shaft....and NP231J as a tranfer case...

A NV4500 behind a 2.5? Definitely a case of overkill. Probably need a bigger engine just to turn the transmission <img src="/forums/images/graemlins/lol.gif" alt="" /> Maybe an AX15 upgrade?

Chef Mark was running 4500 behind his 2.5 till the 3.5 chipmonks kicked the bucket, now he is doing a 5.3 vortec.
