I'm having a strange problem with my snake. It's a 2007 Shelby with 16,000 miles on it. While I've read about the clutch issue's occuring before 20k, I can't be sure that it's the same problem. When I drive the car in 4th, 5th, or 6th gear and give it to much gas, the car slips out and back into gear. The shifter knob doesn't physically pop out while this occurs. I can recreate it almost every time. (seems like as soon as the super charger kicks in it slips). Any idea's are welcome.
