Alum Transmission 2nd Generation 19in OAL

The BERT BERT Transmissions Alum Transmission 2nd Generation 19in OAL (model SG-1300) is a specialized manual transmission designed for high-performance automotive builds where precision gear selection and durability matter. Built for drag racing, street rod, and circle track applications, this second-generation aluminum case transmission delivers the lightweight construction and reliability that serious engine builders demand. Whether you're upgrading a vintage hot rod or constructing a dedicated competition vehicle, this unit provides the foundation for consistent power delivery and repeatable performance.

This manual transmission features two forward speeds and reverse with an internal hydraulic clutch system, eliminating external clutch lines and simplifying underbody packaging—a critical advantage in tight engine compartments. The aluminum case construction reduces overall vehicle weight compared to iron alternatives, improving acceleration and handling dynamics while maintaining structural rigidity under sustained load. The 10-input spline interface ensures compatibility with a wide range of engine packages, and the compact 19-inch overall length allows flexible installation in custom chassis and vintage frame conversions without excessive driveline angles or packaging compromises.

Mechanics and fabricators specializing in hot rods, custom street machines, and racing platforms recognize BERT Transmissions as industry-standard components for builds requiring bulletproof reliability and straightforward installation. The internal hydraulic clutch design simplifies pedal assembly and reduces mechanical complexity, making this transmission ideal for restorations and competition vehicles where every pound and inch of space counts. Confirm your specific input spline, output shaft configuration, and driveline architecture before ordering to ensure seamless integration with your engine block and rear axle assembly.
