Hello, my opel is behaving oddly. Sometimes when I shift it vibrates when letting out the clutch. Its not all the time, but it is becoming more frequent. Do I need to look into replacing the clutch? I was planning on doing an upgrade to the s-10 clutch with a getrag 5 speed later on, but if the clutch is going out might as well do the converison now. I am kind of strapped for cash and would like to put it off for atleast another month. What else could this problem be? My tranny and engine mounts looked okay. Its also leaking oil at the clutch, so I can't really put it off for to long. Any advice or experiance with a similar problem?
