Clutch pedal sticking to floor board, cannot get vehicle into reverse gear. Clutch pedal starts feeling squishy and all of a sudden pedal will stick to the floorboard and the clutch will be fully engaged. Have to manually pull pedal up when vehicle is turned off to use clutch again. Reverse gear grinds and will not go into gear around the same time the clutch pedal starts acting up.
