I have a 2012 45th anniversary Camaro that I bought with 5200 miles on it. The clutch chattered ever since I bought it and the dealer said it was normal. Now it slips big time and I'm told it needs replacing at a cost of $1600. I am NOT happy about this. I noticed other threads about the same issue. Is there a TSB out there or any way to mitigate the cost for repair?
