I've had slight clutch chatter ever since I bought my C-6. I only feel it as I'm slipping clutch pulling out of the garage. It was a leftover 05 and I'm thinking that that surface maybe rusted and that is causing it...
Question is shpuld I live with it or take it in??

 

Unless it is really bad clutch slipping, I would give it a bit of time to cure itself. We have had many, many postings here about the "strange" clutch action on the C6. I experienced the same problem you describe along with difficulty in getting smooth starts from a standing stop. I did not like the clutch at all and my wife hated it.
At about 2000 miles it all disappeared. I suspect it is the coiled spring that attaches to the clutch pedal that causes the problem. It seems to me that over a bit of time this spring seems to smooth itself out and the problem goes away.
At present I could not be happier with the clutch on the C6, but that was not the case in the first 3 or 4 months.

 

I also have mild clutch chatter when I move the car very slowly in and out of the garage. I don't notice chatter in regular driving. It's a little tricky managing the clutch engagement, especially on an uphill start.

 

7,000 miles and it's still with me. It's going to the dealer soon.

 

All clutches have "chatter" at some level depending on usage.

I had a Centreforce clutch on my old SS and that thing chattered like crazy.

My C6 has it also just a little mostly when I am accelerating too much in a higher gear going slowly.

 

Mine has a slight chatter when starting slow in 1st or reverse.
It only has 600 miles on it.
I'm not worried about it, the clutch works well otherwise.

 

That is exactly what I experienced. Although I don't know about that spring.

If you're already past a few thousand miles I'd go out and hammer it and abuse the clutch to some reasonable extent for a day or so and see if that cures it. If not I'd bring it in.
As a last resort if you're not getting satisfaction, I'd complain about the clutch 'sticking to the floor' at high RPM. There's a TSB on that one, and they'd have to tear into your clutch to check that. I actually had that problem early on but it went away and I never had it checked out.

 

chatter on oem clutches is mostly caused by uneven wear and resultant hotspotting and glazing of the clutch disc and burring of the steel engagement surface on the flywheel. Once the uneven wear has occurred, it is very difficult to correct. Abusing the clutch with hard starts etc will only hasten the demise of the disc and your trip to the dealer.

We have seen a few cars come in with this condition and have replaced all affected components including the mentioned spring. This appears to be a factory assembly issue on certain cars. Work was done under warranty as a drivability issue and parts were replaced free due to accelerated wear as cited above.

Your best bet for warranty coverage is to get the car to the dealer with low miles - less than 8K miles if a Z51 car due to these tires wearing quickly. If you bring the car in already on a new set of tires, you will have a harder time getting covered. Remember that the clutch is a wear item and is not normally covered, so coverage is discretion of the service manager. The younger the car, the easier to justify abnormal wear. Definitely an issue though...

 

I have 11k on mine and it still chatters. Went to the dealer & they attempted to blow it off as being an accepted issue. I can not accept paying $50k for such crapy quality. I loved all my prevs vettes which makes this issue even more unacceptable & will not settle. Stay tuned...

 

Mine had a chatter for the first few thousand miles and now a 7000 miles it's fine.

 

I think we have to differentiate between: (1) clutch chatter that arises because the MN6 sometimes is hard to get moving cleanly from a standing stop, and the driver deliberately or inadvertently slips the clutch to get the car moving, resulting in a chatter, and (2) clutch chatter that is not a sometimes occurence but is present constantly and you cannot get moving without the chatter occurring.

It is important to understand that the MN6 has a strange clutch action that is much different than your ordinary Toyota. No one seems to know why and there are a lot of theories, but over time, for most people the problem disappears.

In the case of #1 above, the clutch chatter does not always occur and it seems to be driver induced, i.e. sometimes you can get moving without chatter but it takes some skill and a fine touch with clutch and gas. This kind of chatter will likely cure itself over time. This was the problem I had, I was always uncertain whether or not the car would move off cleanly from a standing stop.

The problem was very evident in pulling out of my parking space where I had to get moving from a stop and take an immediate right turn. Releasing the clutch while turning at a slow speed was very tricky. Thankfully, this problem eventually cured itself, I don't know why, but it disappeared.

I would say that as a general rule, if you have a "sometimes" chatter it is not something to worry about because it will likely improve over time.
