Description

Keep your speedometer reading accurately with the ATP Speedometer Drive Gear YA-16, the small toothed gear that transmits transmission output-shaft rotation to the speedometer drive. It's a direct-fit replacement across a wide range of GM-transmission vehicles, including the 1975-1981 Buick Century, 1975-1981 Cadillac DeVille, 1975-1986 Chevrolet C10, 1975-1990 Chevrolet G20, 1975-1981 Chevrolet Camaro, and many more — see the Buyer's Guide tab for the full list of 175 applications.

20 teeth: factory tooth count for correct meshing with the driven gear.
Blue color: molded in blue for quick identification.
GM transmission fit: designed for GM transmissions TH-200, TH-250, TH400, and TH700-R4.
Country of origin: made in the United States.

Worn, stripped, or missing speedometer gear teeth can cause an erratic, inaccurate, or dead speedometer. If a failed drive gear is the cause, this YA-16 replaces it. Choosing the correct tooth count matters — confirm YA-16 suits your vehicle and gearing before installing.

Frequently Asked Questions

What does this speedometer drive gear do?

It meshes with the driven gear inside the transmission to transmit output-shaft rotation to the speedometer, so road speed is indicated.

How many teeth does the YA-16 have?

It has 20 teeth, matching the factory tooth count for correct engagement with the driven gear.

Which transmissions is it made for?

ATP designed it for GM transmissions TH-200, TH-250, TH400, and TH700-R4.

Will this fit my vehicle?

It fits many 1975-1990 GM-transmission vehicles. Check the Buyer's Guide tab and confirm the correct tooth count and gearing for your application before ordering.

What are signs the drive gear may need replacing?

An erratic, inaccurate, or non-working speedometer can point to worn or stripped gear teeth. Diagnose the cause first; if the drive gear has failed, this replaces it.
