After delivery of my new C7 last year the transmission made a "clunk" when shifting from 1st to 2nd. At 700 miles dealer told me to ignore and it would go away after time. Vehicle now has 4000 miles and I took it back to the dealer and said this car still makes noise. Corvette technician took a ride with me and agreed. Found out that a flywheel spring was missing from the transmission and is being repaired. Anyone else ever experience that?
