act 2600, Clutch pedal seemed fine, all of a sudden the pedal got a little sticky and slowly was coming off floor. Then i pulled over and checked the fluid, lines, and pedal assembly. i pushed the clutch pedal a little more and it started to get rock hard. now the pedal will go down about 3inches then just stop. I need to put full force from my leg on the pedal in order for it to go down all the way. Once i put the pedal to the floor car wont go in any gear. If i try to throw it in gear it just grinds and wont Go in. Clutch has about 30,000 miles or so on it. Anybody know what can be wrong?
