COMPOSITION OF LUBRICANT FOR AUTOMATIC TRANSMISSION

摘要

The present invention relates to a lubricant composition for an automatic transmission, comprising 75-90 wt% of one or more mineral oil, 1-10 wt% of aliphatic diester, and 5-20 wt% of an additive. The lubricant composition for an automatic transmission according to the present invention has low low temperature viscosity, and thereby having improved low temperature fluidity, and has improved low friction properties by using mineral oil having high paraffin-based hydrocarbon in the mineral oil to be efficient at reducing the fuel costs. And the lubricant composition has low viscosity at high temperature, thereby preventing abrasion of internal parts of a transmission to improve durability.
