<P>PROBLEM TO BE SOLVED: To provide a transmission oil system for preventing the shortage of a lubricating oil amount for a lubrication required portion such as a PTO gear 2 in a PTO device and resulting wear or seizure by securing a sufficient lubricating oil amount for the PTO (power takeoff) device for a transmission. <P>SOLUTION: The transmission oil system comprises a torque converter oil path connecting an oil pump to a torque converter for the transmission so that oil flows to the torque converter, and a hydraulic control valve provided therein for controlling hydraulic pressure in the torque converter oil path. Herein, a return oil path for relief oil connected to a relief oil outlet of the hydraulic control valve is connected to the PTO (power takeoff) device for the transmission so that the PTO device is lubricated by the relief oil. <P>COPYRIGHT: (C)2008,JPO&INPIT |
