Abstract
A hydraulic control apparatus may include a first valve bifurcating hydraulic pressures of two pressure control solenoid valves, a second valve selectively supplying one pressure from the first valve to first chambers of first and second actuators and another hydraulic pressure from the first valve to second chambers of first and second actuators, a third valve bifurcating hydraulic pressure from the first valve, a fourth valve selectively supplying one pressure from the third valve to first chambers of third and fourth actuators and selectively supplying another pressure from the third valve to second chambers of third and fourth actuators, and a fifth valve selectively supplying one pressure from the third valve to a first chamber of a fifth actuator and an exhaust port and selectively supplying another pressure from the third valve to a second chamber of the fifth actuator and the exhaust port.
