GM Speedometer Driven Gears
TCI Speedometer Gears are precision machined from high-quality materials and designed to fit most popular transmissions. Speedometer gears include both a drive and a driven gear. The drive gear is located on the transmission's output shaft. The driven gear is positioned in a removable housing that is typically located in the transmission's tailhousing. Chrysler and Ford speedometer gears are built into the outer shaft and can be used on any Chrysler or Ford transmission. Choose from many gear options with a variety of tooth counts.
Whether you have a GM, Ford, or Chrysler vehicle, the formula below is useful when no established baseline exists.
