Time, wear and extended competitive driving in your C4 Corvette with a manual transmission will eventually wear out the Corvette Clutch Master Cylinder, causing shifting problems. Longer clutch recovery time between speed shifts is often a symptom of a worn clutch hydraulic system.
Replace your worn 1989-1996 Corvette Clutch Master Cylinder, Clutch Slave Cylinder or Hoses to get the clutch response you deserve!
