Bad Clutch? / Need Some Advice
Hey Guy's,
I just bought a new C6 Z51 (900 miles on car) and there seems to be something wrong with my clutch. I'm not sure it's the clutch and here is where I need some help/advice. When I'm driving at slow speeds10mph or less and I'm about to come to a stop, I push the clutch in and the car actually jerks as if the clutch was not disengaging correctly. It doesn't happen every time but most of the time. I left the car at the dealership, and as usual, they couldn't duplicate the problem. I went back and went on a test drive to show them the problem. The dealership kept the car for two days and said they could not figure out what was wrong with the car or if there was anything wrong with it. I picked it back up today and I'm stuck with the car having the problem.
Are any of you experiencing the same problems? If so, any idea of what the problem is? Has anyone had this issue and received a fix from the dealership?
Appreciate the help.

When you re-engage your clutch, does it start to engage very soon off the floorboard?
Many people complain of just the opposite and the clutch engages for them way back on its swing. If you reduce the clutch throw it helps this problem. But if you go too far and reduce the throw too much, the clutch might not completely disengage, and may start acting like your problem.

Don't know if this is it but it is worth a shot. See if your VIN is in the range.

Mine engages low,which is fine as I have no problem with disengaging. One thing I've noticed, maybe similar to what you describe, maybe not: when pushing in the clutch at slow speeds to engage 1st, the engine revs up. Nothing to do with clutch being disengaged, but a noticable increase in revs. No problems with it doing this, but unusual ime.

I had the problem where I couldn't tell when it would engage or dis engage. The service manager took it for a ride but stalled it three times before he got it out of the parking lot. I paid the difference and had a Z06 clutch assembly put in, end of problem.

blacksix, it sounds like your Z51 clutch is behaving normally compared to mine. Engagement starts right off the floor, but I get some shuddering when attempting to start slowly up an incline. I can reduce the problem by keeping the rpm up, but sometimes it's just there. I can live with this idiosyncracy...I could not live with variable and touchy engagement at the top of the travel. I've never seen a production car with so much variability in the clutches.
Edit: oops...blacksix, I reread your post...No, that doesn't sound right; mine doesn't do that...See my response above to Whiterock1 as a possible reason
