Abstract: For a 2.fwdarw.1 shift, a timing solenoid valve SL5 is maintained at a duty cycle of 0% (off) for an interval TE=1.5 sec from the initiation of the shift operation and then the duty cycle is changed to 100% (on) after the TE interval so that an oil pressure of a brake B.sub.2 is maintained low during the shift operation while the oil pressure is increased to a high oil pressure for transfer of a maximum torque used in the first speed range upon completion of the shift operation. In response to a switching of a shift lever from D or S range to L range, the timing solenoid valve SL5 is energized with a duty cycle of 100% (on) at 2 sec after such switching to provide a high oil pressure for transfer of the maximum torque, thus preventing a shift shock from occurring as a result of a switching from D or S to L range.

Abstract: A hydraulic control apparatus for an automatic transmission has friction elements for performing a downshift by releasing one friction engaging element and engaging another. The apparatus includes duty control valves connected to the friction engaging elements, duty solenoid valves connected to oil lines for supplying pilot hydraulic pressure to the duty control valves, and control means. In a case where a release duty signal is outputted to one duty solenoid valve to control the pilot hydraulic pressure to thereby release the one friction engaging element, and downshift is a power-on downshift, the control means raises the duty ratio of the other duty solenoid valve to a predetermined valve to raise engaging hydraulic pressure supplied to the other friction element when rotational speed of the transmission input shaft is greater than a difference between the product of output shaft rotational speed and low-side gear ratio and a rotational speed commensurate with a delay in engine speed upturn.
