Shift control device for automatic transmission

A shift control device for an automatic transmission, comprising:

• a power transmission mechanism having a drive power transmission path for transmitting drive power, and a reverse power transmission path for transmitting reverse power;
• a drive friction engagement element for selecting the drive power transmission path, and a reverse friction engagement element for selecting the reverse power transmission path;
• and
• a hydraulic control valve for controlling the supply of engagement control hydraulic pressure to the drive friction engagement element and the reverse friction engagement element,
• wherein the hydraulic control valve has a main pressure supply source for supplying the main pressure of the engagement control hydraulic pressure, a manual valve that is switched according to shift lever operation, first and second main pressure oil lines disposed in parallel between the main pressure supply source and the manual valve, and a plurality of engagement element oil lines disposed between the manual valve and the drive and reverse friction engagement elements, and
• a linear solenoid valve that allows the main pressure to be set as desired is provided in at least one of the first and second main pressure oil lines.
