TCI high-capacity automatic transmission drums are designed to use high performance frictions and steels, which significantly increase lock-up surface area and allow the drum to hold more torque. Excess material is removed from these high-strength cast steel drums to reduce rotating mass. Oil holes allow fluid to escape these drums and permit the piston to engage quicker. A standard needle bearing is stepped into these high-capacity drums to reduce friction and drag. TCI high-capacity automatic transmission drums feature high-strength, forged-steel clutch hubs built extra-tall to accommodate additional clutch plates.
