Mid Plate Gasket

The Mid Plate Gasket is a precision composite sealing component engineered for Richmond Super T10 transmission systems. This tailshaft housing gasket is essential for preventing fluid leakage and maintaining system integrity in manual transmission assemblies. Built to exacting OEM specifications, the Mid Plate Gasket ensures reliable sealing between critical internal surfaces, making it indispensable for both original equipment applications and high-performance rebuilds where durability and leak-free operation are non-negotiable.

Constructed from composite material, this gasket combines resilience with excellent conformability to mating surfaces, accommodating minor imperfections while maintaining a consistent seal across varying clamping pressures. The composite formulation resists thermal cycling, transmission fluid degradation, and mechanical stress—common failure modes in high-demand drivetrain environments. Precision-molded dimensions of 9.55 x 2.8 x 10.1 inches ensure proper fitment and alignment within the tailshaft housing assembly, critical for preventing micro-leaks that compromise transmission performance and fluid levels over extended operation.

Technicians and transmission builders rely on this Richmond OEM-equivalent component when overhauling or servicing Super T10 gearboxes in muscle cars, hot rods, and performance vehicles. Whether restoring a classic transmission to factory condition or rebuilding for enhanced durability, the Mid Plate Gasket provides the sealing performance required to prevent costly fluid loss and internal contamination. Installation is straightforward during mid-plate assembly, and the lightweight composite construction (0.34 lbs) ensures minimal mass while delivering maximum sealing reliability throughout the transmission's service life.
