PROBLEM TO BE SOLVED: To provide a lubricating oil composition for a transmission excellent in fatigue life, low-temperature viscosity characteristics and extreme pressure characteristics even in a low viscosity, particularly in a transmission such as an automatic transmission, a continuously variable transmission, a manual transmission, and a final reduction gear. To provide a suitable lubricating oil composition for a transmission. SOLUTION: (A) A lubricating base oil contains (B) a poly (meth) acrylate additive, and the composition has a kinematic viscosity (Vc) at 100 ° C. of 4.5 to 8 mm 2 / s. A lubricating oil composition for transmissions having a viscosity index of 95 to 200, wherein the kinematic viscosity (Vb) :( Vb / Vc) at 100 ° C. of the (A) lubricating base oil with respect to Vc is 0.70 or more. There is a lubricating oil composition for a transmission. [Selection figure] None |
