Clutch/transmission

This has a hydraulic clutch, so check the clutch system for a leak and if none is found, you may have either a bad clutch master cylinder or a clutch release cylinder.
If there is no bleeder screw on the master cylinder, crank the hydraulic line loose that goes to the release cylinder while someone else presses the clutch down one time and holds it down and check for fluid pressure. If none suspect a bad master cylinder, but if there is pressure, then suspect a bad release cylinder, that is of course if there are no leaks and the master cylinder is full of fluid. I see the release cylinder does have a bleeder.
