Maintain your Chevrolet, Buick, GMC, or Cadillac vehicle with a Genuine GM Parts Automatic Transmission Torque Converter. This converter transfers engine torque to the transmission input shaft and is comprised of a pump and two fans, the impeller and turbine. The pump spins fluid toward the outside of the torque converter, causing the turbine to spin, which results in the moving of the vehicle. Only Genuine GM Parts are tested to meet GM Original Equipment standards and are designed specifically to fit your vehicle. WARNING: Cancer and Reproductive Harm
