Since we don't have the extended powertrain warranty as '07's, we can count down the days until that is no longer covered under warranty. I agree with you, it is totally un-acceptable to me that such a beautiful car should have such an ugly sound. BTW, the manager of the Service Department also said that other GM cars have this same diff and they make the same noise! Unbelievable. And we wonder why Toyota is kicking GM's butt in terms of volume of cars sold. Makes me wanna consider alternatives (e.g. the 08 TT is pretty sweet, has a power top and a decent trunk - albeit it for $16K more)!

After going thru the following.....1. pinion seal replacement, 2. fluid changeout to solve the clutch pack noise....my tech verified my complaint about geat howl at higher speed AND the clunk, and authorized an entire carrier replacement (9/5/07). I think the "instructions from GM" not to do that was so much BS, perhaps SMALL DEALER could add some clarification as to whether such a directive even exists. The carrier replacement has solved all of the problems, now it's up to me to do a careful break-in, and cross my fingers.
