I have the stock clutch in the car with 11,000 miles. Yesterday I was using it pretty hard and on an upshift the pedal came out only about 1/2 way and seem like it caught on something internally. It came all the way out on the next shift, but then did it again when I went through the gears again. No floor mats or anything were in the way and the clutch fluid was full.
After I drove normally for awhile it seemed ok. I haven't driven it hard since. Any ideas, and would changing the clutch fluid help?
