PROBLEM TO BE SOLVED: To improve efficiency in warming-up in a hydraulic control device of an automatic transmission.SOLUTION: In a hydraulic control device of an automatic transmission, a selector valve 35 includes an input port 35c to which a first oil passage L1 is connected, a first output port 35f to which a second oil passage L2 is connected, and a second output port 35g connected to a predetermined portion in the automatic transmission other than an oil cooler 51 through a third oil passage L3. The input port 35c can selectively switch to any one of the first output port 35f and the second output port 35g, according to temperature of working oil in the automatic transmission.SELECTED DRAWING: Figure 1 |
