Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power transmission fluid composition, to provide a transmission containing the fluid, to provide an operation method of a transmission containing the fluid, and to provide a method for improving friction durability of a power transmission fluid. SOLUTION: The power transmission fluid comprises (a) a base oil and (b) an additive composition, and the composition comprises (i) at least one ashless dispersant, (ii) a metallic cleaner giving about 100 ppm or more metal in the power transmission liquid composition, (iii) a friction decreasing amount of imidazoline, (iv) a succinimide friction decreasing agent and (v) a non hydroxy tertiary amine friction modifier other than (iii).
