O'Reilly Synthetic Automatic Transmission Fluid Dexron VI 1 Quart - DEX-VI

Automatic Transmission Fluid; Dexron VI; 1 Quart; O'Reilly automatic transmission fluids provide: protection against wear and transmission shudder; resistance to thickening due to high temperatures; friction stability to maintain smooth and consistent shift performance. Automatic transmission fluid (ATF) is considered the life-blood of the automatic transmission. It is used to transfer power in the torque converter and provide the pressure to apply the transmission's various clutches and bands. It also is used to clean, lubricate and cool the components of the transmission. GM's new transmission fluid, DEXRON(R) VI, was developed to have a more consistent viscosity profile; a more consistent shift performance in extreme conditions; and less degradation over time. Beginning with the design and development of GM's new Hydra-Matic 6-speed rear-wheel-drive transmissions, GM Powertrain engineers determined the need for a new transmission fluid to withstand the complexity of the clutch-to-clutch transmission operation. Additionally, GM engineers identified opportunities to improve viscosity, durability, and impact on fuel economy with a new fluid. "The development of DEXRON(R) VI is the first time an automotive company has worked so closely with petroleum and additive companies to develop a new fluid," says Roy Fewkes, driveline fluids group leader, GM Powertrain. "The result is a new fluid that significantly outperforms existing fluids in every aspect. In fact, we have had to significantly extend the length of our durability tests to fully test the fluid's capability." Internal GM tests have demonstrated DEXRON(R) VI to deliver more than twice the durability and stability in friction tests compared to existing fluids. It also has demonstrated superior performance in pitting, foaming, oxidation and shear stability tests. See car owner's manual for specific fluid recommendations.
