A shifting unit ( 1 ) for an automatic transmission, especially controlled by pressurized medium for an automobile, with multiple valves which are connected to each other through a pressure supply line ( 30 ) and a pressure reduction line ( 32 ). The chambers ( 16, 18 ) of servo cylinders ( 10, 12 ) fitted with servo actuators contain at least one shift valve each ( 22, 24, 26, 28 ). There is a pressure accumulator ( 36 ) designed in between the pressure supply line ( 30 ) and the shift valves ( 22, 24, 26, 28 ).
