LUBRICATING OIL COMPOSITION FOR AUTOMATIC SPEED GEAR

摘要

PURPOSE:To obtain a lubricating oil composition for automatic speed gear having excellent frictional characteristics of preventing stick slip without reducing torque transition capacity. CONSTITUTION:A base oil of lubricating oil is blended with 0.01-3.10wt.% diester of a dibasic acid and a dihydric alcohol and 0.01-3.0wt.% polyamide obtained by amidation reaction between a dibasic acid and a diamine based on the whole amount of a composition to give the lubricating oil composition for automatic speed gear.
