The Coan Racing COA‑22159 Rear Servo Cover Gasket is a precision-manufactured sealing component engineered for TH400 transmissions. Crafted in the USA to Coan’s stringent quality standards, this gasket creates an effective seal between the rear servo cover and the transmission case, ensuring reliable hydraulic integrity under high operating pressures. Its exact fit prevents fluid leaks and maintains consistent servo piston function, essential for optimal band application and shift performance.

Designed for both race-prepped and routine maintenance builds, the COA‑22159 forms a leak-proof barrier that helps sustain performance and prolong transmission life in demanding environments.
