    摘要： An automatic transmission includes a first rotating element provided by a sun gear of a second planetary gear set, a second rotating element provided by coupling carriers of the second planetary gear set and a third planetary gear set to each other, a third rotating element provided by coupling ring gears of the second and third planetary gear sets to each other, and a fourth rotating element provided by a sun gear of the third planetary gear set. The second and third planetary gear sets are combined with a first planetary gear set so that the automatic transmission can provide seven forward gear stages by changing a combination of two engaging elements, such as clutches and brakes, for coupling or stopping the corresponding rotating elements.

    摘要： A control system for an automatic transmission includes a first frictional engagement element and a second frictional engagement element; and a first hydraulic servo for controlling the application/release of the first frictional engagement element and a second hydraulic servo for controlling the application/release of the second frictional engagement element. A regulator valve regulates the oil pressure to the first hydraulic servo. A signal pressure is applied to the regulator valve to establish a predetermined gear stage by switching the applied/released states of the first frictional engagement element and the second frictional engagement element by feeding/releasing oil pressure to/from the first hydraulic servo and the second hydraulic servo. The regulator valve includes a valve member having: a first pressure receiving area to which is applied the feed pressure to the first hydraulic servo as a feedback pressure in a first direction; a second pressure receiving area to which is applied the signal pressure in a second direction opposite the first direction; a fourth pressure receiving area to which is applied the feed pressure to the second hydraulic servo in the first direction, in a shift wherein the first frictional engagement element is released while the second frictional-engagement element is applied; and a third pressure receiving area to which is applied the signal pressure in the second direction, for regulation of the oil pressure only during a shift.
