To provide a vehicle transmission control device that reduces vehicle shock caused by FB torque that is output due to rotational speed FB control, at the time of shifting when the engagement clutch is meshingly engaged based on a rotation synchronization determination. In a hybrid vehicle, rotational speed FB control on a second motor/generator (MG2) connected to a first engagement clutch (C1) is carried out when there is a gear shift request to a gear shift stage at which the first engagement clutch (C1) of the multistage gear transmission (1) is meshingly engaged. A transmission control unit (23) is provided for outputting a meshing engagement instruction to the first engagement clutch (C1) when a rotational speed FB control causes a differential rotation speed of the first engagement clutch (C1) to be within a range of a synchronization determination rotational speed. Upon executing the rotational speed FB control on the second motor/generator (MG2), this transmission control unit (23) makes the efficacy of rotational speed FB control less than before starting of the meshingly engagement, when the meshing engagement of the first engagement clutch (C1) is started.
