Abstract
Transmission lubricant compositions comprise a mineral oil as a base oil of which % CP and % CA defined in ASTM D 3238 are 70 or more and 3 or less, respectively, a viscosity index improver, and a friction modifier. The transmission lubricant compositions have excellent low temperature fluidity, shear stability, and durability of anti-shudder properties and thus can be used for extended periods of time.
