Description
Swap in a modern 5-speed or 6-speed manual transmission, and your factory speedometer will lie to you. The final drive ratio changes that come with these transmissions mean your original speedo gear can't produce an accurate reading. This 7-tooth speedometer drive gear restores accuracy by providing the correct rotational input to your mechanical speedometer cable.
The drive gear mounts on the transmission output shaft and meshes with the driven gear in the tailhousing. Tooth count on both gears, combined with your axle ratio and tire diameter, determines speedometer accuracy. This 7-tooth configuration is the factory-standard count for Ford manual transmissions and serves as the baseline for calculating which driven gear you need for your specific combination.
Yellow color-coding makes identification simple during installation or when troubleshooting speedometer issues. The precision-molded construction delivers consistent tooth spacing for smooth, reliable engagement with the driven gear. This is the correct drive gear for all Ford T5, T45, and Ford T56 manual transmissions.
