TCI Circle Track Transmission and Torque Converter Combo

Product images may differ from actual product appearance.

Circlemax Transmission and FastLap Torque Converter to be the perfect solution.

Due to a significant increase in efficiency, this combination reduces engine speed 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 the use of GM TH350 transmissions, there is no better choice for asphalt or dirt racing competition. As with every TCI transmission or 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.
