Confused about not using clutch in mud

I don't understand how you're supposed to rock the Jeep back and forth when stuck yet still not use the clutch.

To Prevent mud/debris from getting In between the pressure plate/disc/flywheel.
Scoring and causing damage.

You can start the jeep in gear using 4 low.
Just use a higher gear.

Not sure what you mean be rocking ?

When you get stuck you can go into first gear then reverse then first gear then reverse etc , it takes a little bit of timing but eventually the momentum of rocking the Jeep back and forth gets you free. They even mention it in the operators manual but how would it be possible to do this with out using your clutch.

This is one reason why I have an auto trans. You can shift in the water/mud without destroying everything.

I have a manual and have had to rock my jeep out the mud many times I have never had a issue with doing it either. All the trucks I have had also have been manual the rocking works best when stuck in mud IMO sand you can do it but you have to watch what your doing or you will dig in deep if you dont know what your doing. The main reason I have a manual now is so I can rock it I am from FL and you will be doing if iff you offroad much there.

The clutch is more of an issue when you are in water. Thick gooey mud isn't an issue, water, or muddy water is.

Me too. I wheel with some folks who play in the mud hard every chance they get. Then I get to read about said folks fixing something else that's broken on their jeep the following week.

Question QUESTION:: How deep can you go before it is a problem

Does anyone know where the vent/hole the water can get into is on the transmission? I'm assuming the top?

I'm guessing that this guy, in the picture below, would be able to shift safely. Looking at the brochure cut-away (really tried to find this pict from page 6 ), it seems the top of the transmission is about at the top of the Rubicon's wheel. So any higher than the axles you need to cross your fingers. To split hairs about it, if the vent is on the very top of the trans it seems you would be alright as long as you could open your door without crap coming in.

i could be wrong but i think its through the top so the trans would have to be mostly underwater for it not to be safe to shift?

So basically what your saying is if you get in over your axels don't rock the Jeep?

There is no way to rock it in 4 low with out a clutch.

You're correct... the breather holes for the trans and diffs are on the top or at least very near to the top.

The clutch opens up at the bell housing does it not? The automatic transmission has the same issue if you talk about vent lines but when you shift in a manual it allows dirt and debris to get in between the plates because you separate them to shift. This has nothing to do with vent lines or am I mistaken?

Two separate issues. You're right about the manual...shouldn't shift when you're in deeper water or all sorts of junk will get into the clutch.

The breather tubes are on both diffs, the transfer case and the tranny (except on a manual, which has no tranny breather tube). For the most part, they run up to or beyond the top of the wheel well. If you're gonna be fording water deeper than that, it's a good idea to raise them.

Also, you should make sure they're attached a little better...stick hose clamps on the base so they don't pull off in water and foul your diffs, etc.

Here's a thread about the breather tubes that MarineHawk started awhile back...title says it's for the '12, but it applies to all JK's: '12 JKUR Auto - Raising the Breathers

Actually the Manual 6spd DOES have a breather tube look under the inner shift boot and you will find it as I have extended my breather tube for my 6spd manual.







Instead of extending the breathers with hose you can go this route of breather creepers which I have done with my diff's. They are water tight and have not fallen off on any of my mud dips or off-roading adventures.

Water gets into the manual transmission from the bottom of the trans. Where the bellhousing attaches to the front of the transmission there are slots in the housing.

That's good to know! Everything I've seen on the JK breather tubes has said there wasn't one on the manual tranny...

One more thing for the list. Thanks for the info.

Part of that is correct, there are slots but that is at the bellhousing (clutch, flywheel) The transmission where the gears are and gear oil is sealed.

Agreed, but the OP was asking about using the clutch in mud. Thin soupy mud or dirty water enters the bellhousing thru these slots and gets in the clutch.

Right I was more less making sure newbies wouldn't get the transmission and the bellhousing confused and think mud/etc will get in the tranmission. Well it can if you go keep enough but that's deep

I learned this lesson the hard way. I went mudding once for less than an hour and got stuck once and my jeep has less than 2500 miles on it. Now chrysler won't cover it under warrantee because its the clutch and they want me to pay $1350 to fix it.

So is the moral of this, buy an auto if you mud? I was wondering about this this other day. Will I now have to winch every time I'm stuck since I can't rock and dig myself out without fear of destroying the clutch ?

Hopefully you wheel with a buddy, and when you get stuck just get a little tug. You can do mud and rock it all you want, you just can't do it in deep mud. I try to avoid mud I can't crawl through like the plague. I hate cleaning it off and I don't like getting stuck

Anyone know why it is set up this way? Is there a way to seal those slots without getting in the way of functionality?
