    Abstract: PROBLEM TO BE SOLVED: To provide a lubricant composition having friction durability, both shudder prevention performance and low temperature viscosity limits of an automatic transmission fluid for multiple automobiles.SOLUTION: A lubricant composition contains a) a base oil, b) 2,5-dimercapto-1,3,4-thiadiazole (DMTD), derivatives of DMTD or a mixture thereof and c) a friction modifier. The friction modifier is produced by providing a first reaction product by reacting olefin containing at least 40 wt.% of Cto Cvinylidene olefin and maleic acid, anhydride or ester, and aminating the first reaction product with an effective amount of a base nitrogen-containing compound to provide the friction modifier. The Cto Cvinylidene olefin is represented by the following formula, where Rand Rare each independently (Cto C) alkyl, cycloalkyl or cycloalkenyl.
