Push Sleeve

The BERT Transmissions Push Sleeve (Part 24) is a precision-engineered internal transmission component specifically designed for builders and mechanics working on high-performance manual gearbox assemblies. This compact yet critical part functions as a bearing surface and load-transfer mechanism within the transmission's internal clutch stack. Whether you're rebuilding a street machine or restoring a classic hot rod, the Push Sleeve plays a vital role in ensuring smooth engagement and consistent pressure distribution across drivetrain components.

Manufactured by BERT Transmissions—a respected name in custom and performance gearbox engineering—this push sleeve is machined from hardened steel or alloy material to withstand repeated engagement cycles and sustained load under acceleration. Its compact 1.5-inch cubic footprint belies its engineering precision; the sleeve's design is optimized for use with specific clutch configurations, ensuring reliable performance under various driving conditions.

Professional transmission builders and performance enthusiasts rely on OEM BERT components like this push sleeve when executing complete transmission rebuilds or upgrades. Its lightweight 0.19-pound design minimizes rotating mass while maintaining the structural integrity required for both street and racing applications, reducing parasitic losses and improving overall drivetrain efficiency.
