Description
This component is part of a speedometer gear set, which includes both a drive gear located on the transmission's output shaft and a driven gear housed in the transmission's tailhousing. Different driven gear housings may be required depending on the tooth count. TCI offers a formula to help calculate the necessary driven teeth for various setups, which is particularly useful when replacing a transmission or when a baseline is not established.
