摘要： Disclosed herein is a hydraulic control system for an automatic transmission wherein a first friction unit (C3) is engaged in downshifting from the 4th speed ratio to the 3rd speed ratio and it is engaged in downshifting from the 4th speed ratio to the 2nd speed ratio. A first port (124g) of a 3-4 shift valve (24) communicates with the first friction unit (C3) and it is allowed to communicate with a second port (124h) when the 3-4 shift valve (22) assumes a downshift position thereof. The second port (124h) communicates via a first passage (454) with a fluid conduit (412) supplied with an actuating fluid pressure. A second passage (452) is provided which connects the second port (124h) to the fluid conduit (412). The first and second passages are provided with first and second orifice devices (662, 660), respectively. The second fluid passage (452) is blocked when a 2-3 shift valve (22) assumes a downshift position thereof.

摘要： A hydraulic control system comprises a pressure regulator valve which generates a line pressure in response to a throttle related pressure and a cut back pressure. The throttle related pressure varies in a pattern corresponding to the pattern of output torque of an engine. The cut back pressure appears at low rotational speeds of a transmission output shaft and varies with an increase in the degree of throttle opening and decreases with an increase of rotational speed of the transmission output shaft. The line pressure, therefore, varies in a pattern corresponding to the pattern of torque supplied to a transmission input shaft through a torque converter.
