AN AUTOMATIC TRANSMISSION OIL COMPOSITION IMPROVING FRICTIONAL PROPERTY AND FUEL ECONOMY AND A CLUTCH FOR AUTOMATIC TRANSMISSION COMPRISING THE SAME

摘要

The present invention relates to a composition used in a clutch for automatic transmitters. More specifically, the present invention relates to an automatic transmission oil composition capable of improving abrasion resistance as well as fuel efficiency by enhancing efficiency of the automatic transmitter through an increase in a friction coefficient of the clutch. To this end, the automatic transmission oil composition is composed of 68-80 wt% of base oil; 5-15 wt% of polyalkylene glycol oil; and 3-10 wt% of a succinic anhydride derivative.
