The Speedo Drive Gear 18-Tooth GM 250C/350C/375B is a precision speedometer drive component designed for General Motors automatic transmissions, specifically the Turbo 250C, 350C, and 375B platforms. This essential gear plays a crucial role in ensuring accurate speedometer readings by converting the rotation of the transmission output shaft into calibrated pulses for the vehicle's instrument cluster.
Constructed to meet OEM specifications, this 18-tooth gear is engineered to maintain the correct ratio between transmission speed and speedometer needle deflection. A worn or damaged speedo drive gear can lead to erratic speedometer readings, which are common in high-mileage or modified vehicles. This replacement gear is designed to restore accurate odometer and speedometer function without the need for recalibration or electronic compensation.
Ideal for anyone involved in restoring classic Chevys or rebuilding transmissions, this gear is compatible with vehicles from the 1960s through the early 2000s GM lineup. Its installation requires access to the transmission output housing, making it a straightforward task for mechanics and enthusiasts alike.
