Which of the following statement is correct with regard to a hydraulic control unit?

A. The various hydraulic signals are converted into electric signals and are used to operate each gear's magnet clutch so that gearshift operations can be performed

B. The volume of fluid within the torque converter is adjusted so that the efficiency of transfer of engine power to the transmission can be controlled

C. The unit's flow channels are switched in response to a number of different hydraulic signals so that the pressure directed to each of the gear's clutches be controlled and so that gearshift operation can be performed

D. The hydraulic pressure which is applied to the gear unit is regulated to achieve the same effect as achieved by engagement and disengagement of the clutch in a manual transmission
