I just went for a short drive in my 2003 ZO6. I was at a light reached for something on the floor and had a sort of hard take off. Popped the clutch a bit. Went to shift to 2nd and the pedal was half way to the floor. Continued to third and went further down. Drove home in 3rd and then pedal sank all the way to the floor? Fluid ? clutch?
