I just bought an '09 GT500, & I'm getting a "shudder" from my clutch sometimes when I take off. Evidently it's fairly common. I'm still researching, but apparently there "used" to be a TSB where Ford would replace the clutch with the upgraded 2010 one, but that TSB is no longer applicable. There's a lot of threads on clutch issues over on the TeamShelby forums, & I'm just starting to go through them.
I've had 6 other Mustangs, but this is my 1st Shelby. I absolutely LOVE the car!
