Product Description
TR580 TCC Boost Valve Kit
Sonnax Part Number: 823740-12K
NO TOOLING REQUIRED
In Subaru TR580 transmissions, the TCC boost valve wears the inside diameter of the sleeve due to constant valve oscillation. When wear is significant, oil leaks past the valve preventing it from properly stroking the converter clutch apply valve into the release position, leading to engine stalls and converter overheat. Sonnax TCC boost valve kit 823740-12K restores hydraulic integrity to the circuit with tight tolerances and proper material.
