Hello, I'm new to having this kind of car and I've been having some problems with the transmission. I have a 2008 convertible, and the clutch has been getting stuck whenever I push it down. Instead of popping back up the pedal's been staying on the floor, and I can't change gears. The car wouldn't start for a while, but I swapped the clutch safety switch and now the car starts but I still can't change gears. Would anyone be able to point me in the right direction to getting this car fixed?
