Summary: | According to aspects of the disclosure, provided is a transmission control system to enable smooth engagement of meshing engagement means When establishing a forward gear position by engaging the meshing engagement means and a forward clutch while a vehicle is stationary. For example, when a synchro device is operated so as to establish a predetermined forward gear position, it becomes difficult to smoothly couple a first speed drive gear to the input shaft by the synchro device. However, temporarily engaging a reverse clutch during the process of operation of the synchro device allows a reverse torque to act on the first speed drive gear to apply torsion to a power transmission path between the first speed drive gear and a driven wheel. Furthermore, a repulsive force is applied and generates backlash between the synchro device and the first speed drive gear, thus enabling smooth operation of the synchro device. |
