Transformative Engineering for Racing Excellence
The General Motors Turbo-Hydramatic 400 (TH400) transmission is a powerhouse in the automotive world, known for its robustness and versatility across various applications, from off-road trucks to drag racing. Despite its impressive performance credentials, one key aspect where the TH400 has room for enhancement is efficiency, particularly in racing scenarios. This is where the Sonnax Smart-Tech drum module 34555-01K steps in, offering a groundbreaking solution.
Understanding the TH400’s Inherent Inefficiency
Traditionally, the TH400’s direct drum counter rotates, introducing inefficiencies in the 1st to 2nd and 2nd to 3rd gear shifts. This cycle demands significant energy, which not only saps power but can also lead to internal part failures due to the stress and shock on the transmission components during shifting.
The Sonnax Smart-Tech Drum Module: A Game Changer
The Sonnax Smart-Tech drum module addresses these inefficiencies head-on. It’s an innovative upgrade uniquely designed to optimize the drum function by introducing a blend of lighter yet stronger components. This module significantly reduces the weight of the counter-rotating components by over 3.3 lbs compared to aluminum direct drums. More importantly, the reduction in energy required to stop and restart the components during gear shifts is a remarkable 53%, thanks to the strategic placement of the module’s weight closer to the centerline.
Key Features and Benefits
- Enhanced Wheel Horsepower and Acceleration: The reduction in rotational mass directly translates to increased wheel horsepower and better acceleration.
- Reduced Shock on Shifts: Smoother transitions between gears enhance durability and the overall integrity of the transmission system.
- Complete Kit: The Smart-Tech drum module replaces both the forward and direct drums and comes with a comprehensive kit, including a six-friction forward clutch pack and a seven-friction direct clutch pack.
- Patented Technology: Holding Patent 11,773,925 B2, this module is a testament to Sonnax’s commitment to innovation.
Compatibility and Installation
The Smart-Tech drum module is tailored for racing applications, specifically those not using a front band. Its design is compatible with the GM TH400 transmission, ensuring seamless integration for racers seeking that extra edge.
The Sonnax Smart-Tech drum module 34555-01K is more than just an upgrade; it’s a transformative component for the TH400 transmission, pushing the boundaries of performance, consistency, and safety. Whether you’re a professional racer or a performance enthusiast, this module is a worthwhile investment for anyone looking to unleash the full potential of their TH400 transmission.
