my 2006 Corvette Z06 has a lot of slack in the drive train. It makes a clunking sound when in 1st gear as the slack is taken in while accelerating and returns as I de-accelerate, mostly in 1st gear.Is this a defect or repair issue or a trait inherent in the new 505 hp Z06’s?
Drive train slack is usually cause by a combination of necessary clearences,it can get excessive when a part fails. I checked for TSB’s on both manual and auto trans Corvettes. The issues is mentioned more on auto trans cars.
You may want to explore dual mass flywheel issues.
May I suggest a Corvette specfis Forum?
