So I recently had my pressure plate, slave cylinder and clutch disk replaced at the dealership under warranty for my 2010 C6 Base. This was about 4000 miles ago. Today, I was taking off at a red light under light load and I hear a very loud POP and the next thing, I had very little forward momentum and I heard a grinding noise coming from the rear of the car (sounding like in the trans). The noise happens in all gears and is consistent with the RPM of the car only when in gear. Anyone have a clue what this could be. I have 40,000 miles on the car so it is still covered under the Powertrain Warranty and anything to do with the clutch and pressure plate should be covered under the work that was recently done at 35900 miles. Just looking to see if anyone has knowledge or have experienced a pressure plate letting lose or a drive gear coming apart.
Thanks.
BTW, the car will move forward very slowly while in gear even with the horrible grinding noise.

Something sounds gawdawful bad, what it could be is anyone's guess.
Strictly a dealer problem now, will be very curious to learn what they find so make sure to update.
Sorry to hear, good news is you're covered under warranty, ideally should be better than new.

Hopefully the Louisville market has two Chevrolet dealerships, might be time to give the other a shot. Sounds like the car's at Bachman now, will have to allow them to do the job since GM's paying, anyway.
Used to live in Evansville, had a good dealer there (Northside); but, we're talking some distance away from you -- assuming they're still in business after the 'reorganization'. Love to believe there's at least one competent dealer in a market the size of Louisville, KY.
In case you don't know Chevrolet assigns CSReps on the forum.
Find one & PM them your story. Make sure you've all the proper documentaion at the ready if asked, OK?
In the meantime wait hfor this matter to be resolved, hopefully to your satisfaction. Nothing (they've done) has happened, yet.

I have sent the Chevy CS Rep a PM. Hoping to hear back. Before this happened, for the past several months I have been experiencing some gear clashing when changing from 1 to 2 to 3 at moderate RPM (between 3K and 5K). Again, I am not sure what broke lose, but I am being told that GM will only cover loaner for 3 days for warranty work and Bachman is telling me they won't even have someone able to look at it until mid next week. I love the care, but I am wondering if I made a serious mistake in purchasing it or if I am just doomed by my choice in dealer. I only have two other choices in the Louisville area. Bob Hook and Montgomery and word on the street is, neither of them are any better to deal with. Plus Bachman is host to the local Corvette Club in Louisville.

Diagnosis... Broken Axle. So, I've read on here that the C5 2004 model axle works in the C6 as a suitable replacement and they are thicker. Any idea on where to find these and how hard are they to replace?

It appears to be the passenger side axle near the transmission. I think it might be the coupler that physically connects the axle to the tranny. From what I can tell, the axle is covered under the powertrain warranty. But who knows. Guess I will find out when I pick it up. Anyone have any idea if the car should sit for 24 hours to let the locktite setup on the axle nut? I mentioned this to the service manager and he assured me that, that is not the case and the car would be driveable immediately following the repair.

Don't these people read their own bulletins? TSB's #07-04-95-001A and #08-04-20-003 say do not drive car for 24 hours to allow Loctite to cure.

The axle shaft is one unit. The u-joint or as GM calls it the CV is probably bad.
When mine went it slung grease all over the underside of the car.
The axle shaft slides into the differential. The differential is attached to the Transmission.
Yes. The car needs to be parked for 24 hours according to the TSB.
I would ask them to place the old axle nut on after the new one to be used as a lock nut.

Thanks for setting the record straight, Harry.
The nincompoops didn't let mine sit 24hrs so despite having the upgraded nuts I suspect one or both are loose, again.
Oh well it's only Chevrolet's money they're wasting, because I will be back and they will fix it right.

Easter-egg troubleshooting and constant re-work gets expensive and eventually dangerous. If they are giving you one ounce of pushback, they would be looking for a new service manager or a new car.
I don't want to sound like an alarmist but I personally would have come unhinged. Then again, this is why I prefer to do as much work as possible on my bikes and cars, understanding this is quite different in that it is MAJOR work covered by waranty.

!
Adding axle nuts to end links (which do NOT remain tight), a normal person would've assumed a solution found by now. Nope. Nevermind poor Harmonic Balancers & lousy valve guides. Freaking axle nuts.
I regret not being more specific in stating my issue's a warranty item.
Saftety notwithstanding if this malarkey was on my dime, they'd have got a what-for long ago. My Z06 is garaged for WI's Winter, on 'life support'. Safety, for now, is a moot issue.

Chevrolet issues TSBs (ie Technical Service Bullitin), Joey. The #s provided by 'JohnHarry' are:
#07-04-95-001A
and
#08-04-20-003
Write the TSB#s down, give them to your SA & ask s/he reads 'em.
Hand them the TSB #s, let THEM argue with Chevrolet.

I gave them the TSB's and they are stating that they do not apply to my year, 2010. I asked them to provide me with some assurance as to what makes the 2009 so different from 2010 in that there is not a need for Loctite on the axle nut. I am sure they are running around trying to make this determination to provide me with answer. I was also told by this dealer to feel free to seek a second opinion. I explained that the Forum is my second opinion and I run all the work they do here. Like replacing my clutch, pressure plate and slave cylinder and not resurfacing the flywheel. Simple mechanic 101 stuff.
