Abstract
The present provides a shutdown shift schedule which allows a vehicle driver an increased number of gear states to increase driveability. This method monitors the gear state conditions indicative of the gear state which said automatic transmission is in. When the shift state conditions vary from predetermined standards, the controller uses the shutdown shift schedule in place of the shift schedule for changing gears of the automatic transmission. This shutdown shift schedule is adapted to allow a 3-1 shift when the shift solenoid is in a shift D position and the shift state is 3. The shutdown shift schedule is also adapted to allow a 3-2 shift when the shift state is 3 and the shift solenoid is in the shift 2 position.
