Abstract: 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.

Abstract: A gear shift operation device for a vehicle to which a multiple-stage automatic transmission is mounted, is provided. By a control lever being manually operated in a range switchable mode, a range position is switched at least between a D-range where automatic transmission is performed and an R-range, and by the control lever being manually operated in a manual transmission mode, a gear change is performed. An operation reaction force when the control lever is manually operated is set larger when the gear change is performed in the manual transmission mode than when the range position is switched in the range switchable mode.

Abstract: An internal combustion engine control system retards a fuel ignition time based on a deviation in the intake air quantity from a predetermined target intake air quantity which is necessary to keep an internal combustion engine idling at a predetermined idle speed. The fuel ignition time is retarded when a transmission is shifted into a neutral range so as to cause a quantity of intake air to converge with the predetermined target quantity of intake air. An engine speed of the internal combustion engine thereby converges with the predetermined idle speed.
