Quick! I Need HELP! whats going on????

Ok guess my Tj just took another unexpected dump on me! I was drving down the road and when i went to shift gears i pushed the clutch pedal in and it went limp!!! I pumped it up and it got a little stiffer and i switched gears. i pulled over and popped the hood and check my fuild in my clutch Resivor and its full! I pumped it up for a little bit and i was able to get it into gear to drive home but everytime i shifted i had to slam it in! I drove home and just as i started to pull in to my drive my dash beeped at me and the check gauges light came on and i noticed my oil pressure dropped for a sec and then went back. and then 2 secs later it did it again. my jeep isnt making a wierd noises but when i came to a stop it seemed to shutter a little before i turned off the ignition. What is going on guys? Ive had this Jeep for 2 weeks and im not sure what could be going on with it!

My uneducated guess is that you may have some air in your line somewhere. From what I understand (someone please correct me if I am wrong) air can be compressed, liquid cannot. You pumping the pedal is compressing the air to the point that there is enough pressure to actuate the clutch. After a while, the pressure dissipates and you are back to where you started. I am not a mechanic and could be way off. I had a similar problem with a motorcycle years ago and this is what I remember someone explaining to me.....

I've never heard of a hydraulic clutch before.
Clearly my mechanical skill-set is inadequate to be of any meaningful help.
Thats why I lurk around here...and just keep soaking up info.
GreenMachine, I think your rig is haunted.
Between the weaving from lane to lane, and freakish systems issues, I'd be pi$$ed after only two-weeks of ownership.
It is a gorgeous Jeep, though. I hope you can find the problems.
keep us updated, plz.

Master or Slave cylinder? I had a Ford Ranger that did this to me on vacation.. It was the Slave Cylinder.

Just for the hell of it, are you sure the resovior is full?

The reason I ask is simply this: On one of my vehicles it has a rubber gasket or grommet or whatever it's called that goes into the resovior. It has to be removed when adding fluid. If it is not taken out, you can pour fluid in it until it runs down the side, but you are never actually putting fluid into the resovior itself. This drove me nuts and I just happen to ask someone about it at a family get together. He pooped my hood, took the top off, pulled the gasket up, poured that fluid in and added more. fixed problem right there on the spot.

I never knew about that little piece of rubber needing to come out to fill it up.



Yours may not have this, and if it does have something like that it should not have to be forced or ripped out, it should simply lift out.


Probably not the problem but just a suggestion.

Yea it has that piece of rubber in it. I just took it out and checked it again and there is plenty of fluid in it. I pumped it up again and it stiffened up a little and i can easily shift between gears but i know that as soon as i try to drive it i will make it a few blocks and it will go limp again..

Since you are able to pump it up and change gears, I would try bleeding the slave cylinder. Here's a link to a write up.

Sticky: How to bleed AX-15 with external slave cylinder - JeepForum.com


You clutch may also be going. If you can do it yourself, there is an excellent writeup on here: [Install] AX-15 New Clutch Install


I would start with the small things and go from there though before you go ripping stuff apart.

I think the dash issues and the clutch are unrelated. What you described with the check gauge light coming on, gauge needles doing strange things, and engine almost stalling are indications of a bad battery. I would have your battery checked.

I'm not sure about your clutch issue. good luck.

Hey Gaddman, Semper Fi! Ok guys i went out this morning and took the rubber thing out of the clutch resivor and pumped my clutch for a lil bit and put it back in. My clutch feels alot better but not 100% but good enough that i drove around for a lil while and had no probs...hmm whats the deal with that? But im thinking a new slave cylinder from Autozone with a Lifetime Warrenty for $63.00 is prob a good idea. i noticed that there was a lil fuild on it when i got under my Jeep so it might have a slow leak or sumthing. Im gonna try and drive to work for a min and hope i dnt get stuck sumwhere!

The slave cylinder on my TJ does NOT have a bleeder on it. If there is air in the system (line) I found that parking with the front end down hill does the trick, let gravity work for you!

Wave a hand down there for me, I grew up near Sapulpa!
