Dexron VI/MERCON LV Automatic Transmission Fluid is formulated with a special blend of synthetic base oils, a highly shear, stable viscosity improver and a multi-functional additive package. This unique blend creates a premium, full synthetic, multi-vehicle, automatic transmission fluid that significantly reduces transmission wear. It’s recommended for General Motors and Ford vehicles that specify the use of Dexron VI and MERCON LV fluids respectively; it’s also suitable for use in automatic transmissions that require a JASO-1A (JWS 3309) fluid.
