Should I Rebuild My AX-15

I one of those guys that if pulling the transmission to do the clutch slave swap I'm inclined to replace the clutch, flywheel and syncros in the transmission. The best I can tell all have 130k on them and when cold shifting into 2nd is a little bit stiff or notchy if those are the right terms. For those who might ask I run 10W30 dino oil.

Assuming everything looks OK are there any items in the AX-15 that I should go ahead and replace while I'm in there?

I wouldn't bother opening a trans that only has a minor issue in one gear when cold.

I would tend to agree with you, but since I'm dropping it to the replace the exhaust system and do the TJ down pipe conversion as well it would only be one more thing. In the past having rebuilt and done gear swaps more times than I can count in racing transmissions this looks like it would be interesting.

For me the biggest PITA is removing and replacing the transmission/shifter boot/transfer case/skip plate. Opening a transmission is more like fun.

Sounds like you were going to do it anyway and just wanted ratification. Good luck.

There are some specialty tools on that job. Might want to look into that to make sure you want it bad enough.

I'll read Mean Max's? write up and see if I want to do it. I would kick myself if this minor issue turned into a major problem 6 months to a year after having everything out.

Never watched the video, but Moses Ludel has a 1 1/2 hour video for 3.99 that might also be worth a look.

I had a front seal leak. I never opened a tranny before and did the bearings and syncros. If you have any GB experience it should be easy. The only specialty tools you need are a feeler gage, press, Jig(s) for the press and an external clip puller. Transmission warehouse on Ebay has the best deal on a parts kit. Ophi59 sent me the relative info from the shop manual. I also had a lap top with Moses Ludels guide. It was free. Unless there is a bearing clearance issue it's not hard at all. Even after all that my second gear still shifts hard when it's cold. YMMV.

I tried to search eBay for Transmission warehouse, and couldn't find anything.

Although its local to me, I'm sure they will ship to Ga. They always had everything I needed in stock for my AX-5 rebuild.

Hmmm not sure what they did but I found the same seller but they aren't using the same name. Odd.

Here's the kit I used.
http://www.ebay.com/itm/Jeep-AX15-AX...3D978909178790
It's come down in price. It was $290 when I did mine.

Any way I'd also do the tower seals and bushings. That kit includes it. So far all 3 AX-15's I've been into the tower's seals, seat bushing etc... all needed to be replaced.

My experience with rebuilding and a lot of good comments from guys like Ophi59.

^^ Concur. This is the site from where I purchase my rebuild kits. Transparts Warehouse, "Acerl" on fleabay. I am not stumping for a particular product or vendor, I am just endorsing what I have used so many times successfully and without issues, so that is where I keep returning. Rebuilding the AX 15 is a personally satisfying and enjoyable endeavor. Should you run into issues with the shift shafts and interlock pins, I have an FAQ thread specifically on that. No, not an "expert," just a hobbyist with a significant interest in clutch systems, and manual transmissions.

....I'm not smart, but I can lift heavy things.......

Fill out your PROFILE, and don't forget to look in the FAQ for writeups

Just my $0.02, but if you're opening it up anyway, why not consider doing the granny gear swap out of a toyota tranny?
I ask this with no knowlege of if you take your jeep on the rocks or anything.

I think I might be at the point of needing to rebuild or even replace my trans. On Sunday, a guy in a 2001 Honda Civic hit me in the front driver side wheel so hard, i think it pushed the axle back? It broke part of the driver side leaf spring. Bent some other stuff by the front wheel. The impact was so hard that the front drive shaft got jammed back into the trans, that it CRACKED the case! Still awaiting an inspector from his ins co (State Farm), to look at it. It's a 93 YJ. And they already told me they are likely going to total it. But it's all i have and so i will buy it back and get it fixed with whatever rest State Farm gives me for it. It has 155K miles, so yeah, just wondering if this might just be a good time to replace the trans? I have no idea how much a rebuilt one costs? Or could i have them rebuild mine? Thanks!

First of all, don't tell State Farm that it took out your Transmission. Because the drive shaft is connected to your transfer case. Tell them it took out both. Tell them how much you have put into restoring this classic Jeep. Make sure you know there is no physical damage to yourself, if you were in the Jeep at the time.
