TH350 2-Speed CircleMax Transmission™ & FastLap Torque Converter™ Combination

Perfectly matched transmission and torque converter combination makes it easy to select the right drivetrain parts for your circle track application.

Circle track racers looking for the ultimate transmission/torque converter package will find the TCI® TH350 2-Speed CircleMax Transmission™ and FastLap Torque Converter™ to be the perfect solution. This performance-matched combination is engineered to operate in second gear, yielding reduced converter slippage, often a concern with automatic transmissions of this type.

Due to a significant increase in efficiency, the TCI® TH350 2-Speed CircleMax Transmission™ and FastLap Torque Converter™ Combination reduces engine rpm by 300-400 rpm for better temperature control and provides an increase in throttle response and acceleration. Best of all, it provides maximum engine braking to help slow the car down going into the corner, making it perfect for stock cars and trucks that are limited on allowable rear end gearing. For classes that mandate use of GM TH350 transmissions, there is no better choice for asphalt or dirt racing competition. As with every TCI® transmission/converter, these units are triple tested (including a complete dyno certification of the transmission) and rigorously inspected to provide unmatched performance and race-after-race durability.
