摘要： An automatic transmission control system having a hydraulic control circuit for supplying operating pressure selectively to a plurality of friction coupling elements (A 1 ,A 2 ) to place the transmission in desired gears includes a pressure generator for generating operating pressure and supplying it to specific coupling elements which operate in response to operating pressure at different highest levels and an accumulator (C) having a spring loaded piston which provides an increase in operating pressure at a rate variable according to movement of the piston, the rate being greater for greater piston movement as compared with for smaller piston movement, the accumulator being brought into communication selectively with the specific coupling elements by means of a switching element (D).
