TCI Torque Converters, Transmissions, Shifters, Flexplates, Flywheels and More


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 current TCI product line-up includes Transmissions, Transmission Packages, Torque Converters, Transmission Accessories, Transmission Internals, Transmission Mounts, Transmission Fluids, Shifters, Valve Bodies, Electronics, Flexplates, Flywheels and Transmission Coolers.

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.
