Control system for transmission

Abstract

A control system for a transmission includes first and second engagement devices and a controller. The first engagement device brings first dog teeth of a first member into engagement with second dog teeth of a second member to enable torque transmission therebetween. The second engagement device connects a third member and a fourth member while changing a torque transmitting capacity therebetween. The transmission establishes a predetermined gear stage by bringing into engagement the first engagement device and the second engagement device. The controller is configured to bring the first engagement device into engagement while reducing a torque transmitting capacity of the second engagement device and then to increase the torque transmitting capacity of the second engagement device, when shifting a gear stage from another gear stage established by bringing the first engagement device into disengagement while bringing the second engagement device into engagement to said predetermined gear stage.
