ABSTRACT:
An oil pressure control means for operating an automatic transmission for automobiles in a manner to establish various speed shift stages in accordance with the balance of the throttle pressure and the governor pressure, including a combination of a brake-sensitive control means operating in response to operation of a brake pedal and an oil passage change-over means, said combination being adapted to supply the line pressure, in lieu of the throttle pressure, to a speed shift valve which establishes the highest speed stage when the brake pedal is stepped on so as positively to shift the speed shift valve to its downshift position by overriding the balance of the governor pressure and the line pressure.
