Consumer Description

Clutch Slave Cylinder at 51,000 miles failed causing vehicle clutch to not return and loss of fluid. Brake fluid and clutch fluid are used in the same reservoir and could cause issues causing vehicle to not be able to stop. Vehicle has been inspected by shop and has been replicated. The part exploded and leaks fluid inside of transmission housing. This also causes the clutch to fail as-well. Vehicle has always been serviced and maintained and this is a common issue with all vehicles that have 6 speed manual transmission with varying mileage. It is not a matter of if, it’s when and due to this being something that happens with generally no warning signs can be dangerous. There needs to be an updated part that can handle the design Toyota chose for this transmission.
