This is a service VME regarding 1997 through 2002 Corvettes. We’ve had several complaints of the clutch pedal not returning when depressed. If air gets into the hydraulic clutch system, the clutch pedal may not return when depressed. This may occur at low speeds, when stopped or possibly during high RPM shifts. One source of this condition may be the clutch slave cylinder. If the clutch pressure plate was not evenly torqued to the flywheel it may have been distorted. This could result in the clutch release fingers being uneven causing the clutch slave cylinder to wobble. This wobble will eventually damage the internal seal and the slave cylinder allowing air to enter the system. If this situation is present the recommended repair is to replace both the clutch slave and clutch master cylinders. A visual inspection of the pressure plate release fingers for wobble, which would appear similar to a bent wheel, should be performed when servicing the slave cylinder. If the release fingers are found to have this condition, it will also be necessary to replace the clutch assembly. Evenly torquing the pressure plate to the flywheel is necessary to prevent this condition.
Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
