Hydraulic control unit and hydraulic control method for an automatic

reach hydraulic control device for an automatic transmission (10) having a hydraulic power transmission device (32) with a lockup clutch (L / U), and wherein a plurality of hydraulic engaging devices (C1, C2, C3, C4, B1, B2) selectively engaged to to achieve a transition from a variety gears having different gear ratios, said hydraulic control apparatus comprising: a first solenoid valve (SLU) which controls an engaging pressure of a first engagement device that is at a first predetermined gear is engaged and which is at a second predetermined gear disengaged; a second solenoid valve (SL2), which controls an engaging pressure of a second engagement device that is at the first predetermined gear is disengaged and which is at the second predetermined gear is engaged; marked by at least one oil passage selecting means for selecting between a first oil passage used for controlling an engagement pressure of the first engaging device, and a second oil passage used for controlling a torque capacity of the lockup clutch (L / U), and for supplying a first hydraulic control pressure, from the first solenoid valve (SLU) is emitted, which selects for the selected oil passage and between a third oil passage used for controlling an engagement pressure of the second engaging device and the second oil passage and a second hydraulic control pressure from said second solenoid valve ( SL2) is delivered supplies to the selected oil passage.
