Since I got the car (2014 Stingray 1LT Manual), I've had clutch chatter from a dead stop in 1st. It most often occurs on inclines (even slight ones), but also on level ground. More recently a whine has developed. The following video shows the whine (first two clips), the chatter is in the 3rd one. The dealer says this is normal and referenced bulletin 03-07-29-004I. I just can't see how the whine is normal, perhaps the chatter is (but even with that, I'm not convinced). Any suggestions for what to do?
