How Lenco transmissions work in drag racing

Lenco transmissions are unique, high-performance gearboxes used in powerful drag racing vehicles. These transmissions combine features of automatic and manual gearboxes, utilizing planetary gears and clutch packs with a direct clutch for starting. They employ multiple levers, each controlling a separate two-speed transmission segment stacked together to achieve various gear ratios. Lenco transmissions are designed to handle extreme horsepower, exceeding 3,500 hp, making them suitable for demanding racing applications where conventional transmissions would fail.
