Is "clutch chatter" really clutch chatter?
I have a 2006 C6 with the manual 6-speed transmission. I also have the vibration when accelerating from a stop.
I have also noticed that when you let the clutch out slowly, with the brakes applied - there's no vibration. If clutch chatter is the problem, one would think you would feel it when forcing the condition by applying the brake and slowly letting the clutch out - in fact it might be worse. I only get the problem as the car begins to move, never when it is at a dead stop. Also, the condition is not nearly as noticeable when the engine is "revved" higher when releasing the clutch (in other words the higher the rpm when leaving a standstill, the less the chatter).
I don't have any answers but the condition is widespread and, I think, not harmful. I suspicion that it might have to do with the front engine/clutch, rear tranaxle combination - something that GM should be addressing because it would, most likely, be a design or build problem.

Flash back
Ok, Im getting a little aprehensive now. I have an 02 6sp that has that terrible rattle, gm's "keeping everything a little loose to handle the horsepower speech" was heard a million times from the dealers. This is my main reason for getting out of my c5 and into a c6. Has anyone out there gone from a c5 to a c6 notice the same noise, or are we talking about a different noise to deal with?

The C5's made a nasty rattling noise if you put the trans in nuteral, let the clutch out and shut the engine OFF. I did the same expierment to my 06 Z51 today and it DID NOT make the noise.
My tranny/drive train makes no noises but it does shudder at low speed easy take offs and in reverse .
