Default Clutch Problems

I have 8K miles on my 2005 c6 and after going through the rear clutch pack lubrication issue, am still having transmission problems. The clutch take right at the top and has a pronounced shudder during pull away in first and will clunk if the clutch is not depressed rapidly on comming to a stop. In fact in most instances I cannot avoid a clunking in the drive train despite significant proficiency in driving standard transmission.

The Dealer informs me that the clutch is shot and needs to be replaced at 8 hours labour plus parts, at my expense.

This car has never been abused and I consider this to be unacceptable for a car of this pedigree. How do I get the dealer to warranty this item.

Thanks

In your 8K miles, have you by chance opened the clutch master cylinder reservoir to examine the fluid?

Suggest you do that and post what you find.

How many launches or passes are on the car?

What mods are on the car?

Very unlikely that the clutch is worn out, unless your pushing a lot of rwhp and have done a lot of launches.

Did you buy the car brand new? How many miles were on it when you got it? Did you ever lend the car out? Did you ever race or launch hard?

There must be more to this. The clutch is a warrantee item. I had mine replaced under warantee. In fact they replaced the clutch, PP, Flywheel. My complaint was the peddle staying on the floor.

I've noticed lately that when I change gear especially if I'm accelerating hard, the clutch is not dissengaging fully between shifts, it seems to be getting hung up. It's also getting more difficult to engage 1st 2nd and reverse when sitting still. I looked at the clutch fluid and it's almost dark brown! The inside of the reservoir has a lot of jelly kind of stuff over it. I reckon that's where my prblem lies so I'm gonna bleed the system with fresh fluid and see what happens. The car is 12 months old with 5k on the clock. and it sits in my garage all the time unless I take it out at weekends for a blast round the block.

Mine's looked just like that for well over a year, but I haven't had any clutch trouble in almost 2 years.

GM says there's nothing wrong with brown fluid. The color is due to interaction with the seals and is not detremental-

That GM statement was published in 2001 amid a high incidence of clutch pedal woes on LS motors. Five years of pedal woes continued unabated.

With the C6, GM suddenedly put DOT4 fluid in the clutch hydraulics while keeping DOT3 in the brakes. That alone proves GM understands the causative issue for clutch pedal woes is heat to the fluid. In addition, GM began insulating the clutch hydraulic lines on the C6.

And there is a legion of owners who subject their Corvettes to frequent doses of strong acceleration and shifts and never have pedal woes...because they keep their clutch fluid clean through frequent changes. Those that don't get pedal woes.

So what are you gonna believe...(1) a five-year old GM statement that been contradicted by subsequent GM design implementation or (2) what works in the real world?

There is a chunk of owners who never run their cars to 0-100+ at WOT. Those owners generally will not have pedal woes. Black nasty fluid is not something they worry about. But that those car out to a safe spot and hammer out some consecutive 0-120 with red-line shifts and the pedal in those car will start sticking to the floor on the second run.

May be a Canada thing. Most USA dealers will warranty the clutch.

Suggest trying a different dealer, if that's an option.

Here is the web site of the Corvette Club of BC. The next meeting of the BCCC is Oct 4 at the Burnaby Lake Clubhouse 7:00 pm. Bet some members can steer you to a warranty-friendly dealer.

Good luck with the swap.

i agree with the others, try a fluid change worse case it won't make any difference and you end up having the clutch torn apart anyway.

best case, a simple fluid flush and change fixes it and all is well, imo, well worth a try.
