I have 600 miles on my 2006 Coupe and almost from the start I've had a clutch problem. It seems worse when warmed up or in slow traffic. Sometimes the peddle feels normal with about 1 inch of slack before you feel resistance, but most of the time the slack varies randomly, sometimes almost all the way to the floor, making it hard to shift. The amount of slack seems to change constantly. One time I'll go through the gears with just a little slack and the next time the peddle goes most of the way to the floor before I feel resistance. I've talked with my Viper tech and he says there's only a couple parts that could be causing the problem, but he's not heard about this problem (this dealership in Virginia Beach only sells a couple Vipers a year, so I don't think they work on many). Before I schedule an appointment, I'd like to know if anyone knows anything about this problem. Other than that, the car has been great. It's my first Viper, so I don't have any experience with them. I spent months deciding between a new Z06 and this.
