The COAN PG/TH350/400 Front Pump Seal is a precision plastic seal designed for early Turbo 350, Turbo 400, and Powerglide transmission builds. This component is essential for maintaining pump integrity, which directly impacts system pressure and longevity during operation.
This front pump seal effectively prevents transmission fluid leakage at the front pump cavity, ensuring consistent hydraulic pressure for smooth shifts and reliable power transfer. Its design allows for a tight fit within the pump housing bore while preventing fluid seepage without restricting rotational freedom, which is crucial for performance.
Ideal for transmission builders and hobbyists, this seal is suitable for high-mileage transmissions, racing applications, and fresh builds. By using a quality factory-specification seal, users can enhance the efficiency and durability of their PG, TH350, or TH400 units.
