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.
