Jeep will only move in 4wd low?

So I was out playing in the mud with some friends and had no problems all night, but when it came time to leave my jeep would not move. Tried 2h, 4h, and 4l. Tried going forward and reverse in all but the only way i can get it to move at all is by getting it up to 3,000+ rpm in 1st and 2nd gear while in 4l, and even then it still barely moves. Any ideas?

Sounds like you used the clutch while in the mud, not good. Never depress the clutch while in the mud. You will probably have to replace it now.

Would it still go into gear and move if the clutch is shot?

Woah...can you elaborate on this a bit? How do you not use the clutch if/when needed?

Yes. I'd say the buttons are gone off the disk so its just slipping

Simple, don't depress the clutch if you're in water/mud. Stay in gear in 4lo, and if you stall, you can restart without depressing the clutch in 4lo. First rule to learn if you're playing where it's wet and muddy.

Okay. Just went out to take another look at it. I discovered that if i put it in 2h or 4h then put it in gear and let off the clutch without giving it any gas it doesn't die. It'll just sit and idle. does that point to the clutch as well?

First off did you have it in deep enough mud/water to cover the tranny? If you did you could have possibly gotten some trash it that is not letting the clutch engage fully.

People really need to stop telling folks to NEVER use the clutch in the mud, this only comes into play when the tranny is submerged.

You can crawl under it and seen if there is junk in the vent holes below the clutch. Yes odds are verry high that it is the clutch, the only way to really know if you have to just clean it out or replace it is to tear it down.

My bad, I thought that was understood.

I would qualify that to say that the tranny doesn't have to be totally submerged, but rather if the vent holes are submerged. For a jeep that's not lifted, that's not much depth.

The safest bet is to use 4lo, pick the proper gear before you enter the water/mud, and avoid using the clutch unless it's shallow water/mud.

JUST MAKE SURE YOUR TAIL PIPE AND INTAKE ARE ABOVE WATER LEVEL AND NOT FULL OF MUD OR WATER BEFORE YOU RESTART!!!

sorry not trying to step on toes but have seen many hydro lock doing just that and then it can cost a bit if you don't know how to fix it

Okay after cleaning up the Jeep I got underneath and discovered some metal shavings in the clutch vents and it smells like it burned up. So I've got the new clutch I'm starting install now. More to follow.

I did this with a friend who toasted his clutch at Rausch Creek. We also replaced the slave cylinder on his. Just something to check while you're in there. It was a learning experience for him but we got it all buttoned up and back on the trails in no time. He stayed out of the deep mud after that.

Good luck with the install. Stop back in if you have any questions!

Go back up to post #12 and read the last sentence.

I sadly forgot to take pictures of the process. I do have the pic of what was left of my clutch though. This was my first time doing a clutch, but I've been an aircraft mechanic for 10 years so I decided to give it a shot. It was pretty easy. What took the longest was getting under there and finding everything that had to come out. Oh, and most difficult shift knob ever.
