Last night I got in the car to drive home and when I pressed the clutch pedal there wasn't any pressure to it until the bottom. It is stiff and squishy, I have a horrible time getting it into gear, to get in reverse and 1st I have to pump it and give it gas till it finally drops into gear. Once it's in gear there is no slipping and it drives normal but I can't downshift. I just have to let the car coast until I can catch a gear, and it runs up the gears fine, like normal. What could the problem be? Slave cylinder? Thanks and reps will be given.
