Continued Clutch Problems - 02/09/22 10:51 PM

On some 2005-2013 Chevy Corvette vehicles equipped with a manual transmission, the clutch system may fail if unapproved fluids are used to service the system or if a high-pressure pulse occurs during a clutch self-adjustment event.

If the clutch system fails, the clutch pedal may not return if depressed.
If the clutch pedal does not return, it may be possible to start the engine when the transmission is in any gear.

Owners of C6 Chevy Corvette (including Grand Sport, Z06 and ZR1 models) may complain that the clutch pedal sticks to the floor or the pedal stays low.
This may be the result of the clutch master cylinder bypassing. This problem has never been resolved by GM and also existed in the C5s mad

This concern can be identified by having no resistance when the clutch pedal is pulled back toward the top of travel and then pushed to the floor.

The central valve cap inside the clutch master cylinder has likely popped off,
causing fluid to bypass from the high pressure hydraulic line to the low pressure hydraulic line and reservoir.

The clutch master cylinder is not serviceable and must be replaced.
