    • An automatic transmission control arrangement includes an automatic transmission coupled to a propulsion device. A selector device is operably connected to the automatic transmission for selecting a mode of operation of the automatic transmission including at least a forward drive setting. A temperature sensor arrangement measures a control temperature of at least one of a cooling system of the propulsion device and the automatic transmission. A motion sensor arrangement detects a motion status of the vehicle. The controller temporarily operates the automatic transmission in a decoupled mode in which the automatic transmission is at least partially decoupled from the propulsion device with the selector device in the forward drive setting in order to reduce heat generation in response to the temperature sensor arrangement detecting the control temperature is greater than a predetermined temperature and the motion sensor indicating that the vehicle is not in motion.

    • An automatic transmission shift control device include a controller that is programmed to shift an automatic transmission by issuing a command for switching an interference shift element from an engaged state to a disengaged state, and by issuing a command for switching a friction shift element from a released state to a locked state. The controller includes a progressive friction-shift-element switchover section which causes progressive switching of the friction shift element from the released state to the locked state prior to the command for switching of the interference shift element from the engaged state to the disengaged state. The controller includes an interference-shift-element switchover section which causes the switching of the interference shift element from the engaged state to the disengaged state when transmission torque of the interference shift element decreases to a predetermined value as the friction shift element progressively switches from the released state to the locked state.
