ABSTRACT:
In an hydraulic control system for an automatic transmission of a vehicle, when a low range frictional engagement mechanism is engaged in response to shift-down operation of the transmission, a flow regulator valve serves to steplessly regulate flow of fluid from a source of line pressure to the low range frictional engagement mechanism in accordance with changes of travel speed of the vehicle.
