I have a 1997 Chevy S10 LS 4 cylinder manual with 130,000 miles. I was having problems with the clutch about 6 months ago. It was becoming difficult to get in or out of gear. The truck would start moving even if I had the clutch depressed all the way. I bled the fluid and added some more, it fixed it temporarily. Three months ago, it started doing it again and I replaced the clutch with a brand new one? It is now doing it again and I am unable to put it into or out of gear. I started it one morning and it just took off immediately (almost driving throught the front of the garage!) I did not replace the clutch master cylinder when I installed the new clutch.
