Abstract
A method and controller for controlling an electronically controlled transmission in a vehicle propulsion system of a vehicle. The method includes disengaging a clutch in the transmission to prevent a power flow through the transmission in response to an upshift paddle selector and a downshift paddle selector both being actuated together for a first predetermined time period, and changing a ratio of the transmission in response to an actuation of one of the upshift paddle selector and the downshift paddle selector while the clutch in the transmission is disengaged to prevent a power flow through the transmission.
