GM Genuine Parts Automatic Transmission Oil Pump Driven Gears are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These gears help maintain the appropriate pressure in your vehicle's transmission that is required for other components to function. It does so by creating a vacuum that retrieves and pressurizes fluid from the sump reservoir as the pump gears mesh together during operation. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
