TCI Circlematic Transmissions

Not Yet Reviewed

TCI Circlematic automatic transmissions are great for oval track use. However, despite the sound of their name, they also can be used for performance marine applications. All transmissions feature high performance clutches, a steel clutch hub, and a modified planetary gear set that will work with the latest rear suspensions. Many specialty combinations are available.
