TCI? StreetFighter? Transmissions are designed to withstand the rigors of street machines ranging anywhere from 400 to 675 horsepower with a non-supercharged system using pump gasoline, depending on application. Equipped with a TCI? manual/automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. This gives you racetrack shifts and shaves time off your ETs. TCI? 700R4, 2004R and AOD StreetFighter? Transmissions also feature a TCI? Constant Pressure Valve Body? to ensure that clutches and bands are applied firmly to eliminate slippage.

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.
