Mine chattered a bit in reverse when cold but as I've gotten over 3000 miles it's smoothed out to the point it's one of the better clutch activations I've had in recent memory. If it continues have the dealer take a look, it may be a bad pressure plate.
2014 Vette clutch chatter/shutter
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?

Clutch Engagement
Since day 1: Butter smooth. No pulsation/chatter.
If 8000 miles hasn't smoothed yours out, it's time to try something different.
GunGramps, have you ever changed the clutch fluid? It gets dirty super fast on these cars and can affect engagement and feel. Easy to do yourself for about $8.
I plan to do mine every other oil change.

Very smooth for me, too. I have about 6500 miles and no chatter, ever.
Same with mine. EVEN @ -8 degrees!Since day 1: Butter smooth. No pulsation/chatter.

2015 W/7spd very smooth shifting. I believe the clutch is hydraulic activated rather that mechanical, so you will not get the same
feel when the clutch engages, but a little driving and you get used to it.

Do they have a C7 demo you can drive with an M7?
Drive that back to back with your car, and if there's a difference - have the service mgr drive them both and tell you what he thinks then.

Mine has been butter smooth since day 1, I have 9000 miles on it with no vibrations or chatter.
I also experience clutch chatter on my 2015 when engaging the clutch from dead stop in 1st and reverse after it is driven for a while...when cold first starting out no chatter... dealer said to wait for "break in" to complete (about 3000 miles) car now has 2600 miles still chatters I hope it clears up in the next 400 miles. I know it isn't normal for the c7 to do this I drove 6 or 7 c7s over a 2 day period at Ron Fellows driving school and all clutches were as smooth as butter at all conditions. Could GM customer service please respond as this seems to be an issue with many. should we continue to wait for "break in" or is it something that needs early attention?
My 03 Z06 & 2015 Z51 exhibited some mild pulsation in first and reverse, usually in the AM. The mild chatter does diminish as miles are pit on the car. Otherwise "butter" describes it. If the dealer can't find it to be a fault, I suggest having another Vette owner drive your car and getting his or her opinion.
Z51 Clutch chatter and non-Z51 clutch threads have been combined since we are having duplicate posts on both threads.
Mine's always done it a little-worse first thing but consistent-a little more than my C6 & C5 did. 15K miles and no different than when I picked it up.
No chatter on mine, unless I get really clumsy with the clutch.
Just a question of tolerances of parts and assembly, maybe?

This is an update to my post from February (see post #16). My car now has just under 11,000 miles on it, and the pulsation/chatter is mostly gone. Engagement is smooth when car is rolling, at high or low speeds, but when pulling away from a stop, in first or reverse, I can't say it is "Butter Smooth" like other posters have opined. Even though I am an old fart, I still enjoy driving vigorously (much to my wife's chagrin), and an automatic in a car like this seems to leave a little to be desired (but that is just my opinion). This issue has been my only disappointment with this great vehicle, that it has taken this many miles to break in the clutch to the point that it is acceptable.
Since posting the above, almost a year has gone by and a total of 14k miles driven. Mostly my experience continues to mirror the above response. However, on a few occasions I had an off the curve episode worth describing. On few of those occasions the clutch moaned loudly as it was being engaged. Clearly a throw out bearing binding (you’d think?). Also several times the clutch would shutter as it engaged upon a slow start in first. In those cases it grabbed in a very non-linear fashion as if a sticky kids drink was spilled on the clutch surface.My 03 Z06 & 2015 Z51 exhibited some mild pulsation in first and reverse, usually in the AM.

The last time the shutter happened it shook the car violently it was three days ago, I thought the drive line broke or the engine swallowed a valve and worse it again moaned concurrent with the shutter!
Given what happened you would think a trip to the dealer was in order. So would I. But for three days now, no shutter and no moan. Each launch in first gear has butter smooth and with linear engagement.
OMG I’m losing my mind, the clutch is again performing perfectly as it does 99% of the time. If I can’t replicate the problem how will the Dealer?
Reviving and old conversation because I have recently started experiencing judder in my 2015 M7 w/ 15k miles. Started being noticeable in the past couple of months. Seems to not be there when cold but when engine warms up after a few minutes it begins to appear. 1st gear slow starts and reverse are where it happens.
I've had manuals off-on for over 30 years and this is the first I've had that has done this. Our Jeep has more miles on it than the vette and it's clutch has no issues at all.
Seems from those posting to this thread that it is just a crap shoot if you have a car that does this or not. Has anyone had an actual resolution provided?

I like to troubleshoot by starting with the easy stuff, like the clutch fluid. http://www.stingrayforums.com/forum...nce/17998-clutch-fluid-change.html#post331329
I thought the clutch fluid issues / contamination would present themselves as clutch pedal issues. My pedal action is firm and crisp so not sure how fluid change would impact chatter unless I was feeling something off in the pedal action.I like to troubleshoot by starting with the easy stuff, like the clutch fluid. http://www.stingrayforums.com/forum...nce/17998-clutch-fluid-change.html#post331329
From the other forum (which shall remain nameless):I thought the clutch fluid issues / contamination would present themselves as clutch pedal issues.
Q: Hey guys, I have an 05 coupe and for some reason, when I start to engage the clutch in first gear at rpms around 1200-1600 the whole car shudders a little bit as I let out the clutch. I did the rear end fluid change, any other ideas?
A: Search for the Ranger clutch fluid change. Clutch fluid change outs help that same shudder in my car. Many times.
Given that its a $3 and 15 minute operation, personally I'd give it a shot.
Thanks... will give it a try.From the other forum (which shall remain nameless):
