tranny shuddering??

I felt my jeep start to shudder multiple times today.... it only did it when shifting into 5th and or 6th during acceleration... as soon as I put it into one of those gears and let the clutch out it would shudder as if someone was rapidly tapping the brakes for no more than 2 seconds.......... Not extremely concerned as I am under warranty, just wondering if anyone has ran into this before and what it could be

Has happened to me twice in 6000 miles. It goes away before I have a chance to get it to a dealer so I don't know what it is.

It usually is some glazing on the clutch, should go away.

The first time it happened to me was at about 2,000 miles and it lasted less than a day, second time was at just over 5k and it lasted only a few shifts into 4,5,6 then went away. If you take it to the dealer let us know what they say/do, if mine returns I will try to run it out there just to have it recorded.

It's a new clutch, it needs to be broken in.

What happens is the clutch isn't broken in properly and parts of it get glazed up. That's what causes the shuddering. Now, this is from my on-road car days, I don't know if Jeeps have the same problem.

It should go away once the clutch is fully broken in, why doesn't someone that has had this problem before chime in?

Regardless of what it may be, since you guys are under warranty, ask anyway. Also, make sure they note it so if it dies 20 miles after your warranty expires you can be on the record saying that this is a preexisting problem.

Chiming in...I had a shudder in 1st and Reverse for about a day. It was still fairly new but I don't remember the mileage. Got nearly 30,000 miles on it now. I assumed it was the clutch braking in. I have noticed that if I don't fully engage the clutch between gears before accelerating it doesn't respond. I'm thinking there's something in the computer that keeps the driver from slipping the clutch...just a guess.

Oooh!!!


Evolution Lancers have a "ricer-retard-anti-clutch-dump-switch" that won't allow the clutch to fully "dump" at 8k RPM, but rather slips it so as not to shatter any drivetrain parts.

Does Jeep utilize the same idea?
