Is this a good tranny for a 4.0? I know they put them in jeeps with 4.0 but i was just wondering if they hold up being that they use them for the 2.5 aswell?

there very good transmissions and hold good.

2.5 used the AX5 which is wont last behind the 4.0L

4.0 used AX15 which is a great 5sp trans. My buddy runs one behind his 4.5L stroker in a YJ and has one behind a mildly built 360 v8 in his cj5. Ive never heard of one blowing up but i do have one at home that wont stay in 1st gear. Trans + muddy water = bad news but free trans for me

they are clunky as hell but wont break on you ever

yea alittle bit, my 2nd and 3rd syncos are worn out but i can still shift it fine by either double clutching it or slowly easing it into gear.

2nd gear on AX15's are alittle goofy. I drove a newer low milage TJ with the same trans and same issue. 2nd gear can be alittle tricky to get into sometimes, like if you run it up mildly (2300-3000 rpms) in 1st then try to shift into 2nd but it wont go and you have to shift up to 3rd. I get much better shift if i dont run 1st up past 2k rpms, usually like 1500 does great

i have no problems with mine. Little stiff on cold mornings but that's normal.

Where might i find a decent one or one that needs rebuilding? i have the knowledge to rebuild if needed..

Im rebuilding the AX15 out of my 96. A Be@@*%# to rebuild. Give her a good clutch, and im sure that she will last a long time. Worn out clutches kill them syncros.

AX15 can be found in XJ's, TJ's (maybe YJ's too, not sure every YJ ive been around wasnt stock) and if you crafty they also came in Isuzu's but they had integrated bell housings

Don7312

is there a pcm flash needed being a 96?
