Abstract
A hydraulic control system may include control valve to selectively supply line pressure to first and second ejection flow channels, first shift valve converting flow channel, second shift valve converting path to selectively supply hydraulic pressure of the first ejection path to first chambers of first and second actuators and to selectively supply hydraulic pressure of the second ejection path to second chambers of the first and second actuators, third shift valve converting path to selectively supply hydraulic pressure of the first ejection path to first chamber of third actuator and to selectively supply hydraulic pressure of the second ejection path to second chamber of third actuator, and fourth shift valve converting path to selectively supply hydraulic pressure of the first ejection path to first chambers of fourth and fifth actuators and to selectively supply hydraulic pressure of the second ejection path to second chambers of fourth and fifth actuators.
