ABSTRACT:
A hydraulic control for an automatic transmission which comprises first and second friction coupling members, a first fluid passage for supplying an operating fluid for coupling the first friction coupling member, a second fluid passage for supplying an operating fluid for coupling the second friction coupling member, and an accumulator having a working chamber fluid-connected with the first fluid passage and comprising a piston and a spring for urging the piston in one direction. The piston is displaced against the spring, when the operating fluid is supplied into the working chamber, to regulate the pressure of the operating fluid for minimizing a shock resulting from the coupling of the first friction coupling members and also to open the second fluid pssage whereby the timing at which the second friction coupling member is coupled is delayed relative to the timing at which the first friction coupling member is coupled.
