Another problem with my corvette: it does not want to shift into any gear, especially when cold. I can see that I have a good leak under the car and was curious if it couldpossibly be theslave cylinder. The clutch pedal seems to be very close to the floor not having much "pedal". Whereabouts is the slave cylinder located under the hood.

 

I'm not familiar with the C4 but the clutch slave cylinder will be at the bell-housing or inside it.

 

Check the clutch master cylinder on the firewall below the brake master. Slave cylinder is on the driver's side on the exterior of the bellhousing.
