TCI 880027 Speedometer Drive Gear, 17-Tooth, Red Plastic, GM 700R4

The TCI 880027 speedometer drive gear is designed for GM 700R4 automatic transmissions requiring a 17-tooth drive gear. Manufactured from durable red plastic, this replacement component helps transfer transmission output rotation to the speedometer cable or vehicle speed sensor, supporting accurate vehicle speed readings when properly matched to the complete speedometer gear assembly.
Designed as a direct-fit replacement for compatible applications, the TCI 880027 gear is suitable for transmission repair, restoration, and drivetrain service. Its 17-tooth configuration should be verified against the original gear and the vehicle’s rear axle ratio, tire size, and driven gear combination before installation to ensure proper speedometer calibration.
