Abstract: A method for controlling a powertrain includes the following steps: (a) determining whether a vehicle is coasting to a stop based on an accelerator pedal position; (b) determining whether an automatic transmission is in first gear; (c) shifting an input clutch from an engaged state to a disengaged state in order to operatively disconnect the automatic transmission from an internal combustion engine if the vehicle is coasting to a stop and the automatic transmission is not in first gear; and (d) shifting the automatic transmission to the first gear in order to allow the internal combustion engine to be shut down while the vehicle is coasting to a stop.
