Speedo Driven Gear GM 23-Tooth Black

The Speedo Driven Gear GM 23-Tooth Black is a precision speedometer drive component designed specifically for General Motors Powerglide, 200C, 375B, and 475 automatic transmissions. This essential part translates the rotation of the transmission output shaft into accurate speed readings displayed on the vehicle's instrument cluster, making it ideal for classic car restorations or repairs.

Constructed from durable black plastic, this driven gear is engineered to mesh seamlessly with the speedometer drive gear on the transmission output shaft. Its 23-tooth design is specifically calibrated for GM automatic transmissions, ensuring that the speedometer needle movement accurately reflects the actual vehicle speed. The choice of plastic over metal is intentional, as it provides better wear characteristics and noise reduction.

Technicians and automotive enthusiasts working on vehicles equipped with Powerglide, 200C, 375B, and 475 transmissions will find this replacement component particularly beneficial when speedometer accuracy has diminished or the original gear has experienced wear or damage. Installation requires access to the speedometer cable, making it a straightforward task for those familiar with automotive repairs.
