    摘要: A relatively low viscosity transmission fluid composition, transmissions containing the fluids, and methods of operating motor vehicles with the fluids are described. The transmission fluid composition includes a lubricant basestock, at least one active sulfur-containing component, and at least one phosphorus-containing compound. An active sulfur atom content of the composition is greater than about 0.02 wt. %, and a ratio of active sulfur atoms to phosphorus atoms in the composition is above about 5. The composition has a viscosity at 100° C. ranging from about 4 to less than about 7 centistokes.

    摘要: An additive composition and lubricating fluid are disclosed that provide high steel-on-paper friction durability, good metal-metal extreme pressure performance characteristics and synchronizer performance. The lubricating fluid includes a base oil, a succinimide dispersant, a succinimide friction modifier, and a phosphonate. Also disclosed is a method for lubricating a dual clutch transmission employing a plurality of wet clutches, with the lubricating fluid of the disclosure.
