Experiencing a chatter in first and reverse when slowly accelerating. Had 6 previous vettes without this problem. GM field engineer states that all have may have a shutter. (some more, some less) I drove a identical vette with him at the dealer and it had NO problem. He states that GM is willing to change the clutch pressure plate.

Does anyone have a similar problem? and if so, have you determined the cause?

Who has the same vehicle without the chatter?

I've got a base 7-speed (same clutch), 5100 miles, and no occurrence of shudder that I can recall.

Mike from Danville, welcome to our forum! At Ron Fellows I drove a number of different Z51s 7 speed over two days and never experienced any chatter or shutter when slowly accelerating- though admittedly most of the driving was high speed rapid acceleration, we did go slowly when lining up, approaching the track, and returning after the cool down laps.

Only 2300 miles on mine, but no problems with clutch.

My Camaro ss was the same way. This is why I went with an auto in my ZL1, my c7 z51 and my c7 ZO6. Haven't had a clutch problem since lol. Manuals are nice but to many problems and def to harder on the drivetrain than a auto.

So the chatter occurs as you are letting the clutch out (engaging it) or after the clutch is engaged and you are accelerating slowly?

Hello Mike. I have a Z51 with 2000 Miles. No chatter or slippage. I'm in Livermore and most likely doing the same type of driving as you on I580/I680 stop-and-go and around town.

Mike; Welcome and keep us posted on your issue after the pressure plate is changed. See if you can find out if a failed pressure plate spring(s) was the source of the problem. Good luck!

Mike mine chatters a little bit when I am letting it out, depends on how much I am slipping it. I've never really though much about it as all of my previous clutch cars also did it to some extent. It is not enough for me to think anything is up though, so let me know what you wind up doing and what they find.

I agree, mine does the same, especially when cold but it's not uncommon with all the manuals I've owned and only happens in the driveway, not on the road when I'm actually driving it. Certainly nothing worth taking it to the dealer for.

Exactly mjw930, that is when I notice it, backing out of the garage and when I take off the first time pulling away from the driveway. I haven't noticed it after that. I wonder if it is just the cold (not up to temp) clutch disk, plate and flywheel? Again, I do not consider it a worrisome event.

Clutch Engagement

I took delivery of a new 2014 Z51 M7 Vert in June of last year, and was ecstatic about everything in and about the car, with one exception. From the moment I drove it away from the dealership, I noticed a slight pulsation/chatter in the clutch when engaging first or reverse gear. The dealer said to put some miles on the car, and it would probably go away. I drove the car last summer, went on the Caravan to B/G and had a great time. It now has over 8,000 miles on it, and the pulsation/chatter is still there, sometimes barely noticeable, sometimes bad enough that my wife (to whom cars are a necessary transportation evil) says “Gee honey, there’s something wrong with this car?”

I have had it in to two different dealers, and both have told me that it is no different than any of the other manuals that they have driven. It currently resides at the second dealer’s lot, and, after much discussion, he is going to contact the local G/M engineering rep to look at my vehicle and pass judgment.

I have had many cars in my lifetime, an abundance of them with manual transmissions, and have never had anything but linear, smooth engagement of the clutch. The current dealer said that my vehicle has a dual mass clutch, and that probably is the difference. My prior Vette was a 1996 Grand Sport – also with a dual mass clutch, and it was nothing but butter-smooth.

The purpose of this epistle is to ask those of you with the M7 transmission in your cars what the clutch engagement is like when pulling away from a stop in first or reverse. Do you notice a pulsation/chatter upon engagement or is the engagement of the clutch smooth and linear?

Gungramps mine is smooth except for the first one or two engagements of the day. Like when I back out of the garage I notice a little chatter and when I stop then shift to forward there is a little chatter when I pull out. After that it is smooth. Almost like when everything is cold it does it. The chatter is very faint and I think it is normal, at least to me I've never felt like anything was "wrong". Hope this helps.

If the problem is still there after 8K miles and your wife notices it, there is a problem. Keep after the dealership until they take care of it. May need a new clutch.
:cool:

Mine is like greg's. When cold there's a little chatter, but once rolling and warmed up a bit smooth as silk
