Abstract: A composition is provided suitable for use as a friction modifier for an automatic transmission, comprising an N-substituted oxalic acid bisamide or amide-ester containing at least two hydrocarbyl groups of 12 to 22 carbon atoms.

Abstract: A composition is provided for use as a friction modifier for an automatic transmission, comprising a long chain hydrocarbyl amine having one or two additional groups on one or two different amine nitrogen atom thereof of the structure —R3-C(=0)X(R4)c. R3 is an alkylene group or a group comprising a group of 1-4 carbon atoms or a chain of 2 to 9 carbon atoms interrupted by one or two nitrogen or oxygen atoms within the chain; X is nitrogen or oxygen, and R4 is a long chain hydrocarbyl group, or H, or —R3-NHR5. The compound does not contain a primary amino group.

Abstract: A composition useful for lubricating an automatic transmission comprises an oil of lubricating viscosity and a hydrocarbyl amine with a hydrocarbyl group of 12 to 22 carbon atoms and having one or two additional groups of the structure —R3—NHC(O)R4, wherein R3 is an alkylene group of 1 to 4 carbon atoms and R4 is a hydrocarbyl group of 4 to 22 carbon atoms, or a nitrogen-containing heterocyclic group, or an aminoalkyl group.
