ABSTRACT:
A fluid pressure control system for automatic transmission includes a fluid pressure source, a fluid pressure regulating valve for regulating the fluid from the source to a particular line pressure, and a plurality of frictional engaging devices, adapted to be actuated by the line pressure through means of a manual shift valve, for attaining a particular gear ratio within the gear trains of the transmission which are interposed between the input and output shafts. A governor valve generates a governor pressure in response to the rotational speed of the input shaft, a throttle valve generates a throttle pressure in response to the engine throttle valve, and a shift valve selectively actuates the frictional engaging devices in response to the governor and throttle pressures.
