A gear shift control device for an automatic transmission device includes a transmission including an output unit setting and outputting a target value of the hydraulic pressure to the hydraulic control device. The output unit, when the shift stage is changed from a shift stage to another, increases the target value for a first friction coupling portion in the decoupled state in the shift stage to a first value, reduces to a second value, increases to a third value after the value is reduced to the second value, sets to a fourth value after the value is increased to the third value, and sets to a fifth value after the target value is set to the fourth value, and the output unit sets the fourth value according to magnitude of input torque to the transmission.
