To provide a transmission control device for a hybrid vehicle that, when there is a gear shift request, ensures gear shift responsiveness corresponding to a driver's request while achieving excellent gear shifting quality when shifting gears under normal conditions. A multistage gear transmission (1) that establishes a plurality of gear shift patterns is mounted in a drive system from a first motor/generator (MG1) and an internal combustion engine (ICE) as power sources to drive wheels (19), and the multistage gear transmission (1) has engagement clutches (C1, C2, C3) that are meshingly engaged as shifting elements. In this hybrid vehicle, a transmission control unit (23) is provided, which carries out a shift control for switching between gear shift patterns that are established by the multistage gear transmission (1), by a movement of the engagement clutches based on a gear shift request. The transmission control unit (23) selects, from among a plurality of gear shift patterns that can be established by the multistage gear transmission (1), gear shift patterns in which one engagement clutch is present in a power transmission path leading from the power sources to the drive wheels (19), and designates the selected plurality of gear shift patterns as a normal-use gear shift pattern group, which is used for shift control under normal conditions.
