油圧制御装置。The automatic transmission includes a hydraulically actuated friction element, a throttle valve that generates a first control pressure in accordance with the opening degree of the throttle valve, and a throttle valve that generates a first control pressure in response to the first control pressure from the throttle valve. regulator valve that adjusts the oil pressure supplied to the engine, and a selector lever that selects drive range operation that automatically selects the optimal gear depending on the engine operating condition and 2-range operation that enables operation in 2nd gear. A manual valve that works together to generate hydraulic pressure according to the select position for drive range operation and the select position for 2 range operation, and a manual valve that determines the shift timing between 1st and 2nd speeds depending on the engine operating condition
It is equipped with a shift valve that generates hydraulic pressure for speed control, and receives the hydraulic pressure for second speed control and the first control pressure to switch from the drive range operation to the two range operation with the opening degree of the throttle valve being small. Sometimes, in order to increase the adjusted oil pressure from the regulator valve, the second one corresponding to the select position for the two ranges from the manual valve.
A hydraulic control device for an automatic transmission, comprising a control valve that supplies control pressure to the regulator valve.
