御装置。 An orifice control valve that can switch the orifice that adjusts the rate of change in oil pressure is installed in the oil passage connected to the oil chamber where hydraulic pressure is discharged or supplied when shifting from high speed to low speed. A shift control device for an automatic transmission, wherein a valve is configured to be switched to a side that reduces the orifice effect of the oil passage by engine brake pressure output in an engine brake range.
