LUBRICATION SYSTEM OF A TRANSMISSION

A lubrication system of a transmission provides oil passages in an upper portion of a transmission case, and an oil dispensing guider at the transmission case for dispensing churning oil to the oil passages. The oil dispensing guider includes a guiding surface bent at multiple points along a length direction so as to fit bottoms of the oil passages, a slanted guide surface formed along the guiding surface and being slant upward so as to guide oil on the slanted guide surface to the guiding surface, sockets integrally formed at the guiding surface and respectively inserted into the oil passages, and an oil collecting portion formed along an exterior edge of the guiding surface and the slanted guide surface and bent from the exterior edge so as to collect the churning oil splashed toward the oil dispensing guider.
