Abstract: The present invention discloses friction modifier compositions, methods for incorporating an alkoxylated alcohol component in power transmission fluids, and methods for measuring friction performance. These formulations and methods provide improved overall friction and improved friction durability, yielding effective fluids that are stable with age. Benefits in friction modification may also be achieved when the alkoxylated alcohol component is heated with an ashless dispersant prior to its incorporation into a transmission fluid.

Abstract: There is provided an automatic transmission fluid composition comprising a major amount of a base oil; one or more friction modifiers, wherein total nitrogen content provided by the one or more friction modifiers is greater than or equal to about 300 ppm; and one or more ashless dispersants, wherein the total nitrogen content provided by the one or more ashless dispersants is greater than or equal to about 500 ppm. The automatic transmission fluid may have a kinematic viscosity at 100° C. of from about 4 cSt to about 6.5 cSt and a Brookfield viscosity at ?40 ° C. of from about 4,000 cP to about 20,000 cP.

Abstract: A power transmission fluid composition having improved characteristics. The fluid may include a base oil and an additive composition, wherein the additive composition includes an ashless dispersant and an oil-soluble aliphatic tertiary amine. The resulting fluid may have improved durability characteristics.
