I recently rebuilt an AX 15 to swap into my CJ with a Dana 300. I swapped it from internal to external slave and replaced all synchros, bearings, etc. Since reinstalling, it is very difficult to shift into 1st and 2nd gear when running. I can shift back into 1st when I come to complete stop and return the transmission to neutral first. I can shift from 1st to second and 3rd to second if I do a combination of double clutching and rev matching. All other gears shift well, and the transmission will shift through all gears when parked. I'm trying to decide if it's a clutch issue or if I need -
I rebuilt an AX 15 in a 99 Wrangler. It went back together fine, it shifts tight, only 1 problem. Shifting from 2nd to 3rd is fine and from 3rd to 4th is good. I just can't get it to go from 4th to third. I am guessing it may be a ball or shift plug out of place in the rail or intermediate plate. Any thoughts? Thanks Tim -
There has been a long thread of exchanges at Timmy960's topic on harsh shifting after rebuilding an AX15 transmission. The problem around 3rd/4th gear shift issues has a basis in the redesign of the synchronizer sleeve, bronze blocking rings and the third gear cog teeth for the sleeve engagement. Jason Logan and I had an exchange about this issue when he rebuilt his '99 TJ Wrangler unit. That exchange was just prior to the launch of the forums. For the benefit of all AX15 rebuilders, I am starting a new topic around this issue, beginning with the in-depth Q&A exchange that Jason Logan -
Hi, I hope this is the right forum for this. I am doing a resto mod project with my 1956 Willys Pickup. I am in the process of installing a 4.0 from a 2004 Wrangler into it with an AX15 5 speed and Dana 300 transfer case. I rebuilt the AX15 by following the FSM from Jeep Chrysler as well as a few youtube videos. All clearances are spot on. Now that the trans is together I went to bench test it and the shift lever will go through the gears although reverse is slightly harder. I can turn the input shaft by hand in 3rd and 4th gear only. 1st, 2nd, 5th and reverse will not allow me to spin -
Hi to all, Hoping to get a little guidance! I recently completed a rebuild of the AX15 with a master rebuild kit which was uneventful. When it was completed and bench tested, it shifted rather smoothly into all gears, except reverse. It took a few tries each time, but the reverse gear would engage and the output shaft would spin in the opposite direction with no issues once it's engaged. Having read a lot about difficult shifting just after a rebuild, we thought little of it and installed it in the car. Now, we are still having the same issue, but worse. The transmission won't -

Trying to switch from a manual to a auto in a 96 xj. Needing to know what all I need to do other than bolt up. New computer? Different bell housing ? Also what would be the best tranny to use for this auto. It is strictly a off road toy -
Hi Moses I purchased your AX-15 rebuild video on vimeo. I also downloaded the AX-15 service manual before I started this project. When I started this project it was supposed to be a simple clutch install. How ever when I removed the transmission from the Jeep which is a 93 YJ Sahara. I noticed that the pilot bearing had grenaded and part of the inner race had welded its self to the input shaft on the transmission. I figured since I will have to tear the transmission down to replace the input shaft I might as well do a full rebuild since I had noticed some grinding going into 3 -

Members and Guests...We've had some great discussion on rebuilding the popular Aisin AX15 transmission, and my 'how-to' rebuild rental at Vimeo On Demand (http://www.vimeo.com/ondemand/ax15rebuild) has received solid feedback as a resource for shops and DIY level techs! I'm pleased to see many are able to successfully rebuild and thoroughly restore the AX15, made popular in 1989-1999 model year Jeep vehicles with the 4.0L engine. The AX15 transmission rebuild coverage and our discussion here at these forums also serve other applications of the AX15, including the Dodge Dakota, some Toyota tr

Hi, Just swapped out my AX15 transmission on my 97 Jeep Wrangler. After I completed the job, with the engine off, I was able to shift through the gears without issue. I pressed the clutch pedal and it was easy the first few times then became extremely stiff. I removed the external slave cylinder from the bell housing and manually pushed in the clutch fork with my finger. The fork moved forward easily, then I heard something fall inside the bell housing. I pulled the tranny back off and found the clutch fork retaining clip had fallen off. I proceeded to put it back in place ensuring it was s -
In this video discussion, I describe the symptoms of hydraulic clutch linkage leaks in 1987-95 Jeep YJ Wrangler models. Originally part of the Q&A Vlog at the magazine, the viewer's question refers to hard shifting and loss of hydraulic fluid. I share what causes these troubles in this how-to HD video on troubleshooting: Moses

I have recently installed a rebuilt AX15 in my 98 TJ. From the beginning it has been difficult to shift into 2nd and 4th gears. By difficult I mean it requires some strength to pull to engage as if there is a bungee cord opposing the direction I'm pulling. It will engage each time and does not have any noises associated with these shifts. It occurs only while shifting up into these gears. It shifts into all others fine and down shifts into them fine as well. If I have shifted into one of the gears I can shift back into it with no difficulty if I down/up shift momentarily the shift back. Th -
I have a 95 Wrangler with the 2.5L AX-5 combination. I have the opportunity to replace this combo with the 4.2L AX-15. Other then the engine and transmission swap are there any hidden changes that will have to be made for this swap to work? -
I am looking at used jeeps and I will be a first time jeep owner. I am interested in CJs or YJs. I want the jeep mostly for hunting and putt-ing around town. As far as engines go, do you think a 4 cyl would be okay for what I want and not get me in trouble in the mountains, or should I just look at the 6 or an 8 cyl? If a 4 would work, what transmission, axle gearing and tire size would you recommend? I have already found the forums to very informative. Thanks. Rich -
Moses, I know your a hardcore 4.0L, especially stroking one, kinda of guy, but I hear far to many folks say that the AX-15 can not handle V8 (300hp, 300 ft lbs +/-) over time...but some say it can. Would like some input from the "Jeep God" himself. Seems other forums are just opinon. Got a lot of dirt track friends with access to cheap SBC's, Ford 302's and such. Thanks again.

I have viewed you webpage on the AX-15 rebuild. It is great! I have one question though. Where can you find the selective snap rings. I have been trying to locate one in particular and I have been told that it is discontinued with no replacement. The part number is 83506088. It is for the 3rd and 4th synchronizer and is 1.90mm. Do you have any idea where to source this part at? Any help would be greatly appreciated. This one ring is holding me up on my assembly. Thanks! BG
