Manual Tranny Issues new 2012 JK

Hey, has anyone esle had problems with their standard tranny? The clutch engages near the top (release) of the pedal instead of at the bottom. I'm also having some problems trying to get the thing going from a dead stop. I have stalled it 5-6 times in the first 150 Miles. I have to rev it to 12-1500 before I start to disengage the clutch otherwise it will stall.

I don't know if it's me or an issue with the jeep. Any help would be appriciated.

Clutch pedal movement: 100% bottom(pressed to the floor) = 100% top = 0%
The clutch disengages in the top 25% of the pedal range

Time to go to dealer and try another one to see if it's normal.

Mine seems the same way. Try waiting a few seconds after letting off the brake. On hills, mine doesn't really roll for a few seconds after letting off the brake. Its almost like a safety thing for taking off on hills

Mine will do the same thing. The worst part is it's intermittent. Sometimes it works just fine, other times it falls on it ***. If you rev it too high, you'll smell clutch plate, there's a fine line there. I think it has something to do with their eco system and the fly by wire throttle.

It's not you, I drive an 8puc dual friction on the track. It's easy compared to the jk.

If you find the solution, let me know.

I'm going to try and disable the hill start assist and see if that helps. I'm taking it to the service center on Monday to see what they say.

I can start out in first with very little gas. Drive a new one on the lot to see if it's the same. I've only owned vehicles with standard transmissions and it took a couple days to get use to the JK. If you're on flat ground killing the HSA won't help.

I have a '12 JKR. 6 speed and it starts of in first with very little gas. I can get rolling with no gas if it's flat or downhill of course. Never have to rev it up past 1000rpm to get moving.

The clutch is obnoxious on my 2012 JKR, but I got used to it after the first month or so. Hill Start Assist was causing me to stall frequently because I would give it just enough gas to move the vehicle... but not enough gas to move the vehicle while the brakes were on. So I disabled HSA after the first week.

One thing I find is that the clutch in my JK is irritating on the street, but it's so much smoother than my old TJ when offroading. The most charitable interpretation of this would be that Jeep designed the clutch pedal for the frequent in-and-out clutching that is necessary when rock crawling and otherwise driving really, really slowly.
