Lisha: There is a way to adjust your clutch pedal freeplay by loosening the locknut, rotation the pushrod until the freeplay is correct, then tightening the locknut. I am thinking your locknut has come loose and so the clutch just goes to the floor. This is a way to determine the clutch pedal freeplay, you should have that adjusted every 6000 miles or 6 month. So have your mechanic try that. It would be under the clutch pedal in the car. But you should buy a repair manual for your car, even if you take it to be fixed in a shop as you will understand whatever they are doing to your car better. As well as know your car. You can get one at a parts store for around $20.00, I like Haynes it is easier to understand and has good pictures. This is a repair manual. Hope this helps and good luck!
