Alum Trans 2nd Gen Modified w/Shifter 78-SG

The BERT TRANSMISSIONS Alum Trans 2nd Gen Modified with Shifter 78-SG is a purpose-built aluminum manual transmission engineered for drag racing, bracket racing, and high-performance motorsports applications. This second-generation transmission delivers straightforward power delivery with two forward speeds and reverse, designed to handle the unique demands of competition vehicles where consistent, repeatable performance is non-negotiable.

The transmission features an aluminum case construction that reduces weight without sacrificing durability—a critical advantage in drag racing where every pound reduction contributes to acceleration and elapsed times. The internal hydraulic clutch system provides smooth engagement and repeatable shifts, while the 10 input spline design ensures compatibility with common driveline configurations in race applications. The integrated shifter eliminates external linkage complexity, streamlining installation and reducing parasitic drag. At 47.32 pounds, this unit is significantly lighter than cast-iron alternatives, making it ideal for weight-sensitive builds where transmission mass directly impacts vehicle balance and performance.

This transmission is built for racers and serious enthusiasts who demand mechanical simplicity paired with proven durability. The two-speed manual configuration is optimized for bracket racing, where consistent power delivery across multiple runs matters more than wide gear ratio spread. The hydraulic clutch reduces driver fatigue during extended racing sessions while maintaining the precision necessary for competitive timing. BERT Transmissions has established itself in the racing community through products that prioritize reliability over unnecessary features, making this platform a trusted choice among competitors who cannot afford unexpected downtime.
