Transmission Help

Hello everyone! I've been a member for a while but never posted anything so please bear with me.

I have a 1994 YJ with the 4.0L and an AX-15 Tranny. Since i got it about 2 years ago the transmission would always make a loud click when shifting into 3rd but never had major problems. A few weeks ago i was driving it and 3rd gear was stuck and wouldn't come out. I drove it in just 3rd trying to at least make it home and it eventually came out. This happened occasionally for the next few weeks or so. So, I finally decided to take it to Aamco a week ago.

It turns out my Transmission was flooded with water and my 3rd gear took quite the beating . I spoke with the mechanic working on it and lucky me my clutch plate was pretty much worn down to the rivets. He ended up showing me the innards of my transmission and I could clearly see that the 3rd gear was chipped. I think he also said the synchro key was broken, and the 3rd & 4th fork and synchro need to be replaced. On top of all that, he told me ALL of the bearings need to be replaced because of the water damage.

As for the price for the repairs... It's going to be $2600 for him to fix . Which includes the clutch and pressure plate. Being a poor college kid I'm not going to be able to afford $2600 unless I finance it for a while. So, I called them up asking if there was a possibility for me to find and buy a replacement transmission for them to put in. The price went from $2600 to $1300 (for labor, clutch job, and refacing flywheel) plus whatever I pay for the replacement tranny. While I had them on the phone I forgot to ask if i could just supply them with the necessary parts to possibly save a few hundred dollars, but I doubt they would even consider it. I considered just having them just put it back together and taking it somewhere else but they're still charging me for labor, seals, the clutch job/flywheel, and oil which totals out to about $1500 and it's not worth the loss for practically nothing to be done.

Now to the point of this long post. What would my best course of action be? Try to take and cope with the $2600 loss, have them put it back together, or find a transmission to give to them. If anybody has any better ideas, I am completely open to suggestions and other perspectives. Also, if I do try to give them a transmission where would be the best place to look? Thanks for any suggestions!

Swap it dude. It's not that hard. Will cost you a day of your life and a few hundred bucks. It is so easy. All nuts bolts, and if you get a Haynes it will make the whole job simple.

Well I wouldn't have them put it back together to take it somewhere else. If yflthey put it together you swap it. Craigslist and eBay are great for ax15's. I paid $190 for mine with a TC on there. Had to be patient though. Took me a few weeks to find it and I had to drive an hour for it. If they do the clutch it will only cost you the amount you pay for the transmission.

Well good new and bad news! I picked up a AX15 off craigslist and brought it over to the shop. They got everything back together and it drives fine in the forward gears. In reverse it's a different story though.

I paid them and got in ready to take it home but as i was backing out of the parking spot, I felt and heard a clicking noise coming from what i believe to be the transmission/transfer case area. I'm not sure what the problem could even be. Hopefully it's not a bum tranny. The mechanics said that the input shaft was scuffed and he pulled the good one off my old AX15 and put it in the new one but that shouldnt be the cause of the problem unless it was put back together wrong.

The thought that it might be an AX5 crossed my mind but i thought the number of splines on the output shaft were different from an AX15 so it wouldnt have been able to be installed in the first place. Hopefully it's fixed by tomorrow and i'm not just

You are right that an AX5 would not have fit. I say the mechanics did something wrong, or you just need to break it in. I know mine needs double clutching for reverse or it grinds, but that is no big deal at all.

they just told me today that they think it's the tranny. It still drives in the forward gears so I'm just gonna go with it till it breaks and see if i can find a rebuild kit for the old one.

Just got it home! All the gears worked fine on the way here except the reverse. When i pulled in i figured i'd swap into 4WD to see if the same problem would happen in reverse. I shifted in reverse and the moment i started to bring my foot off the clutch it started grinding REALLY bad. I shifted into the forward gears and it moved forward but i got a really bad vibration in the entire jeep... could this be a problem caused by the transfer case?

TC doesn't care if your in forward or reverse.
