Gasket Set - P/G Trans Pump to Case

The Gasket Set - P/G Trans Pump to Case by ATI PERFORMANCE is an essential internal seal component designed for transmission builders and performance enthusiasts working on Powerglide automatic transmissions. This gasket assembly creates a leak-free seal between the transmission pump and case—a critical interface that withstands continuous hydraulic pressure and thermal cycling. Without a proper gasket set in place, fluid leakage, loss of pressure, and internal pump cavitation become inevitable problems that compromise shift quality and long-term transmission reliability.

ATI PERFORMANCE engineered this gasket set to handle the demands of both stock and modified Powerglide assemblies, including built transmissions with upgraded internal components. The pump-to-case interface requires precision fitment and material durability to resist ATF degradation, extreme operating temperatures, and the mechanical stress imposed by high-stall torque converters or forced induction engines. This complete gasket set includes all necessary sealing surfaces between the pump housing and transmission case, ensuring zero leakage and maintaining optimal hydraulic flow under sustained boost or aggressive throttle inputs.

Technicians rebuilding Powerglide transmissions for street or strip duty should use this gasket set during pump installation and final case assembly. Compatibility is universal across all Powerglide platforms—whether upgrading a vintage muscle car, drag racing application, or marine/industrial installation. The lightweight, compact design (0.18 lbs) makes it an efficient replacement component that fits alongside other pump internals and bearing plates. Installation requires only basic hand tools and transmission-specific knowledge; proper torque sequencing and gasket seating ensure a leak-free assembly that delivers years of trouble-free operation.
