TCI? Transbrake Valve Bodies allow you to achieve maximum torque converter stall and provide for quicker and more consistent reaction times and 60-foot times. This is due to the transbrake action which prevents an engine's torque load from being transmitted through the drivetrain prior to launch. The transbrake acts in much the same manner as a manual clutch. Once it is engaged, the vehicle can neither roll forward nor backward, and as you press on the accelerator, the engine can RPM as high as the torque converter stall. Once the transbrake is released, the power is transmitted immediately to the rear tires in much the same manner as a manual clutch but with the parts saving advantage of the torque converter's shock absorbing action.

The original Torque Converters, Inc. turns cutting edge technology into a race winning tradition. When TCI® first opened its doors in 1968, it was a modest operation dedicated to delivering high performance transmission-related parts to a small group of devout drag racing enthusiasts. From those humble beginnings in Memphis, TN, TCI® has grown to be one of the largest and most technologically advanced manufacturers of high performance aftermarket drivetrain products in the world. Currently located in two large facilities in Ashland, MS, some 45 miles from parent company the COMP Performance Group™, TCI® continues to set trends and expand its line of quality transmission torque converter and accessory parts. The original directive, to deliver high performance racing torque converters, is still a core business for TCI®. However, the need for high performance street products, including high-quality automatic transmissions, has increased dramatically, led by an eager contingent of enthusiasts who enjoy improving the performance of their street driven vehicles. Because of these changing trends, TCI® business has changed considerably with 80 percent of their products targeted to street enthusiasts and 20 percent to hard-core drag and circle track racers.
