clutch and redline
anyone else notice the clutch behavior when you really get onto it ? from a standing start (1st gear), and you open it wide up, the clutch seems to suck itself onto the floor. I've shifted, let it out, get nothing, (feels like it's still stuck to the floor), keep shifting until i get to sixth, catching every gear but nothing, eventually i gotta let off the gas to let the clutch come off the floor.
what would cause this ?

Suck and Stuck??? Not following entirely..are you saying that tranny does not engage under full load? If yes you have a problem obviously...I have a MN6 and assure you you can shift under full load

are you talking "traction control" being on (?) or clutch actually sticking to floor? ... if clutch to floor then:
this was - is a notorious problem with C5 ... clutch under "hard" acceleration would "suck" to floor and stick until foot removed from accelerator...GM replaced a lot of clutch/pressure plates...
when this occurs wait for clutch to release itself becuase it is not your tires that are spinning!

yes, same issue.
ok, so what do you recommend. when this occurs, let off the power pedal ?? would a stronger clutch help ? yes, burnt clutch not good.

I see you are still on and no one is replying--my 6-speed C6 has not arrived yet but from previous high HP clutch pedal problems I can tell you Yes- take your foot off the gas to let clutch engage and then drive to dealer and have them adjust or replace the clutch

There isn't a SINGLE car on the market that can sit and spin the tires through 6 gears. You aren't moving because your clutch is engaged. Your tires aren't spinning, and you are probably getting close to blowing that motor. Remind me to NOT buy your car when you get ready to sell

With my 99 C5, the clutch would stick to the floor or half way up constantly. That was a common problem on the C5, but I've never heard of it on the C6. My C6 doesn't have any problem with it, so if your clutch pedal isn't coming all the way back up, you need to take it in for service.

kind of a bummer, really wanna see what this car will do when pushed.
this is the reason some of us get manual transmissions, they can be driven hard when you want to and normal the rest of the time. just like gearing down to slow, i don't gear down just the slow the car but to have total control of what i'm gonna do next. anyone every had to drop it down a gear or two to slow quickly then the hit it once again to say goodbye or to swing around something. just looking for a clutch or combo that will keep up.

I didn't expect the clutch to be fixed but I wanted it on the record. To my surprise the dealer said that there was a TSB on the clutch and they replaced everything;flywheel, clutch, pressure plate, throw-out bearing. I don't know if they replaced the parts with standard parts or used up-graded or Z06 parts (I asked) but I've not had any more problems.

when you say you get on it, how hard are you getting on it ?
here's when it happens to me.
sitting still
put the car in comp. mode
car in first gear
take the rpms to 4k
let out the clutch (quickly but don't drop it), the tires should start to smoke.
keep pressing the go pedal, feel the tires spin
keep the rpms around 5k - 6k (get just below redline, keep it below the fuel shutoff)
press in the clutch, shift into second
let out the clutch (quickly but don't drop it), tires still smoking, or is that the clutch ?
get aggressive with it.
keep the rpms up, step on it, get the go pedal to the floor
press in the clutch, shift into third
let out the clutch, does it come off the floor, did it suck itself in ?
i believe you should be able to notice the issue now, that is if it's not just my car.

You, my friend are burning up the clutch. If you are slowly releasing the peddle at 4000 or higher, you are effectively slipping it. Once this has begun it probably will never recover. And yes that is clutch smoke. The smell must be awful. 
Good luck with warrenty work.

by dropping I mean: press the clutch in all the way to the floor, shift gears, slid foot off of the clutch, moving foot to the left, let the clutch spring back up all by itself. that's what i refer to as dropping the clutch. basically you are engaging the clutch then just removing you foot from the pedal and letting the clutch slam.
when i get aggressive with it I don't drop the clutch but I don't do the slow relase of the clutch either. I release the pressure on the clutch pedal by relaxing my leg as fast as possible but keep my foot over the pedal.
this is when the clutch seems to engage itself, yes i agree it is most likely slipping and maybe i gotta learn to drive a race car (oh now where's my flame suit) but I've never had a clutch act this way before. this is the first vechicle that the clutch will hold itself in and or suck itself to the floor when i get real agressive with it.
have you ever gotten a little steamed and just ran it as hard and fast as you could, that seems to be when it happens the most.
in fact i got smoked by a 94 vette because of this issue. looks like the vette requires more finese than muscle to get all the possible performance out of it.
