Yes. On vehicles with hydraulic clutch systems, the master cylinder and slave cylinder create and transfer the pressure needed to disengage the clutch. If pressure is lost because of a leak, failing cylinder, low fluid or air in the system, the clutch may not release fully.
That can make the vehicle difficult or impossible to shift even though the clutch itself may not be worn out. Certified Transmission in Bellevue can test the hydraulic system and determine whether the problem is hydraulic, mechanical or related to the transmission.
