AX-15 Leaking

So, my AX15 with 330k miles or more is leaking 10W-30. I figured it I could find a shop locally to do a reseal and more than likely replace wear items. I called a couple places only to be told they only rebuilt automatics. The place I did find gave me a quote and it was $1,400. At that point, I can find an AX-15 to buy and swap. So, I will probably learn how to dismantle it and hopefully put it back together. I know Mean Max has a write up but my question is, should I take on this task and is $1,400 really as crazy as I think it sounds?

The AX-15 is pretty much identical to a Toyota R151 (?) and share many internal parts like bearings and seals. Check a few shops that are familiar with the Toyota transmission. It may help.
Parts and labor may not be that far out of line if they have to remove the trans from your YJ especially if they're dealing with rusty and broken bolts. It's not a difficult job but it's time consuming.

Mean Max had a good thread about it with photos. Do you have a FSM Louie? I’ll check mine tonight and see if it has the tear down and reassembly in it.

I might have one I downloaded from a while ago but I have to dig for it.

I followed this guys videos and rebuilt mine....

Other than a press it didn't require any real special tools. Well nothing I didn't have already anyhow.

You can get a reman with a warranty for $895 plus freight shipping if you don't want to tackle it yourself.

I bought my rebuild parts from Transparts Warehouse. I got the deluxe rebuild kit, plus I ended up having to buy a new second gear and an additional set of synchros because I busted one in half. I think I was in it roughly $400 not including the HF press etc.

Check with Casa Grande transmission a buddy of mine had one rebuilt there a few years ago for around $900. Ive had them do a 700r4 years ago and it worked well. Its a little bit of a drive but might save you some money.

Scroll to the bottom and download the 95 Yj manual. AX-15 is in it.

As far as a rebuild yourself. Go for it. Buy a 20 ton harbor freight press when they are on sale. You will come out cheaper and have a press from that day forward which is never a bad thing.

If you cannot fix it with a hammer then it has to be an electrical problem.

I too bought the HF 20 ton press for this very reason when rebuilding my AX-5 and found myself using it far more times than I thought. I also welded up a little slide-in shelf to hold small press parts and tools. Old bearing races come in quite handy at times.

I also made an angle iron and wood stand to help hold the center plate while working on the assembly.

I love the shelf. I need to make one for both home and work. That is freaking awesome.

For manual transmissions I cut a hole through a work bench with a hole saw. I drop the input shaft through the hole and let the case set on the bench and work on the trans while upright. I can spin the trans in any direction to see or work on any side of it easily.

You can buy a brand new AX-15 for around $1600. No way I would spend that on a 300K mi plus one.

Louie, I had my synchros replaced by a guy who worked mostly on Jeeps. He had a TJ and a YJ himself. He charged me $1200, and that was just the synchros.

I'd do it myself now that I know better.

The 4th 5-seater YJ in the world.

Great info and pics guys. I have been putting off buying a press but Now is a good reason. With summer coming and no real opportunity to drive the YJ due to heat, kids, and zero time to myself, I can spend my lunch hour wrenching while I still get to WFH. I just have a hard time spending over a grand on my AX-15 when I could just take it apart myself.

Iíll start saving my HF coupons. Probably when I get a 20% off any item one...which I can probably print online right now.

That's good and you'll be able to get plenty of help here. Keep us updated.

BTW Harbor Freight has all but done away with coupons and all big discounts are through their Inside Track Club which costs money to join. I got the two year plan which came out almost free if done online and it includes a few signup bonuses.
