を特徴とする自動変速機の変速制御装置。[Claims for Utility Model Registration] A shift valve for the nth gear that controls switching between the nth gear, which is the highest gear, and the n-1st gear, which is one gear lower than the nth gear, and the state of the nth gear shift valve. In a shift control device for an automatic transmission having an N-speed blocking valve that can prevent the N-th speed regardless of the speed, and an N-speed blocking solenoid that controls switching of the N-speed blocking valve, a kickdown signal hydraulic pressure is output. a shift valve lock valve that forcibly fixes the N-speed shift valve in the N-speed position when 1. A control unit for outputting an electric signal for operating an N-speed blocking solenoid so as to switch the N-speed blocking solenoid to the N-speed blocking side.
