2011 CTS-V Coupe
So i have now transformed my V back to stock and the only problem left to fix is this clinging sound i get. Faster the car goes, the faster the sound. It doesnt happen until the car has been driven for a while, and only happens when the car is in neutral or if the clutch is pushed in. I thought it may have been the rear but then it would do that whether it was in gear or not right? So now im guessing it's a clutch or transmission issue. I recently tracked the car for half a day and didnt notice this until after the track. Oh and it doesnt seem to be affected by the brakes... Thanks for any and all suggestions. I plan on taking it in to the dealer in the morning, just want to see what you guys think. Thanks again!
