摘要： A shift control system for an automatic transmission is provided, which is mounted on a vehicle configured to be started by an ignition switch being turned on, where an automatic transmission mode or a manual transmission mode is selectively set. The system includes a shift switch through which a manual transmission command for arbitrarily changing a gear stage of the automatic transmission can be inputted in the manual transmission mode, and a controller. The manual transmission mode includes a first manual mode in which the gear stage is changed and maintained by inputting the manual transmission command using the shift switch, and a second manual mode in which the automatic transmission mode is resumed by satisfying a resuming condition after the gear stage is changed. When the ignition switch is turned on, the controller selects in advance the second mode to be set to the automatic transmission.

摘要： A control device for an automatic transmission is provided, which includes a vehicle-propelling friction engagement element configured to be engaged when a vehicle starts traveling, an other friction engagement element, a vehicle-propelling friction engagement element temperature detector configured to detect a temperature of the vehicle-propelling friction engagement element, an other friction engagement element temperature detector configured to detect a temperature of the other friction engagement element, and a processor configured to execute lubricant supply control logic to control supply of lubricant to the vehicle-propelling friction engagement element and the other friction engagement element. The lubricant supply control logic switches the supply amount of lubricant to the vehicle-propelling friction engagement element according to the temperature of the vehicle-propelling friction engagement element, and switches the supply amount of lubricant to the other friction engagement element according to the temperature of the other friction engagement element.
