Abstract
PURPOSE: To smoothly and surely perform the shift down operation of an automatic transmission from its overdrive to second speed shift, by providing a down-shift control valve in an oil line to which pressure oil is conducted when the shift down operation of the automatic transmission is performed.
CONSTITUTION: A hydraulic controller comprises a pressure regulator valve 200 for generating a regulated line pressure, throttle valve 240 for generating a throttle pressure in accordance with a throttle opening degree, governor valve 260, speed selecting valve 210, 1-2 shift valve 220 and 2-3 shift valve 230. It further comprises a timing valve 600 in an oil line 105 as a down-shift control valve for selectively opening and closing said line which conducts an oil pressure generated in a low speed shift output port of the output ports for the speed selecting valve 210 to the 2-3 shift valve 230 as a down-shift control pressure.
