1. A transmission lubrication system comprising: an oil pump that is driven in conjunction with an output shaft of a transmission; a first oil path configured to supply oil discharged from the oil pump to a lubrication system of the transmission; a second oil path arranged in parallel with the first oil path in order to guide the oil from the oil pump to a heat exchanger; a first valve inserted, on an upstream side of the heat exchanger, in the second oil path, the first valve configured to open at a first set pressure to conduct the oil from the oil pump to the second oil path; and a second valve arranged on the upstream side of the heat exchanger and a downstream side of the first valve in the second oil path, the second valve configured to open at a second set pressure, which is higher than the first set pressure, to relieve surplus oil of the second oil path to a third oil path, wherein the third oil path is constructed to lead a suction slot of the oil pump.
