ABSTRACT:
The lubricant composition of the present invention can be used in automatic transmissions and contains 0.05 to 2% of a metallic salt of organic acid (component (A)), such as calcium sulfonate, 0.15 to 4% of a specific polyamide compound (component (B)) and 0.05 to 1.5% of acid phosphate or acid phosphite ester (component (C)) which are added to a lubricant base oil, wherein all percentages are by weight in the total lubricant composition. The lubricant composition for automatic transmissions can show high anti-shudder property, high anti-shudder durability for an extended period, high property of preventing clogging of the friction material, and sufficient transmission torque capacity, while retaining the lubricant characteristic requirements for use in automatic transmissions.
