Time, wear and extended competitive driving in your C4 Corvette with a manual transmission will eventually wear out the Corvette Clutch Slave Cylinder, causing shifting problems. Longer clutch recovery time between speed shifts is often a symptom of a worn clutch hydraulic system. Replace your worn 1984-1988 Corvette Clutch Master Cylinder, Clutch Slave Cylinder or Hoses to get the clutch response you deserve.
