TCI Circlematic Transmissions

TCI Circlematic Transmissions are specifically designed for use in oval track racing applications. Featured inside each transmission#, you'll find high performance clutches#, bands and a steel clutch hub. The Powerglide transmissions contain a modified planetary gear set. On average#, lightweight Circlematic Transmissions are 50 to 60 pounds lighter than manual 4-speed transmissions#, and cost $500-$600 less for a basic automatic setup. These track-tested automatic Circlematic Transmissions are more responsive off the turns#, have quicker engine picks#, and have excellent throttle response in corners and on restarts#, resulting in consistent performance improvements over a standard 4-speed setup. This consistency eliminates the need to have the clutch adjusted before each event. Each transmission is triple tested including the valve body#, static hydraulic pressure#, and final dyno testing to ensure the best performance for your circle track needs.
