PURPOSE: To correctly control a first friction member by providing a second shift valve unit for connecting a first port of a manual valve to a first exit of a first shift valve unit in accordance with the control of a first control pressure, and connecting the first exit of of the first shift valve unit to the first friction member in accordance with a second control pressure. CONSTITUTION: A line pressure source is connected to a first port of a manual valve 160 in accordance with a position of a manual valve unit. In the meanwhile, a first control valve unit is operated by a solenoid to generate a first control pressure, and the first port of the manual valve 160 is connected to a first exit of a first shift valve unit in accordance with the control of the first control pressure. In addition, a second control valve unit is operated by the solenoid to generate a second control pressure, and the first exit of the first shift valve unit is connected to a first friction member in accordance with the control of the second control pressure, thereby operation of the first friction member is controlled. |
