TCI Bracket Racing Powerglides include a new steel stock depth transmission pan with drain plug, a 4140 steel clutch hub, universal shift lever, high-performance clutches and steels and high energy bands. The high-performance clutches and steels provide a high coefficient of friction and high temperature resistance, as well as a grooved surface area to improve clutch apply time. TCI steel plates are engineered from a specially heat-treated steel for increased durability. The high energy bands also have a higher coefficient of friction for higher torque capacity and the ability to produce quicker, more positive band engagement. So while these transmissions are made for lower HP applications, TCI has still used the highest quality materials and internal components to make these Bracket Racing Powerglides the 1 choice for drag race applications making under 700 HP.
