A method of propelling a vehicle with a hybrid mode and a hydrostatic mode includes determining if a current propulsion mode is hybrid and if a selected mode is hydrostatic. A first transition mode is entered if the selected mode is hydrostatic and the current mode is hybrid. An engine-pump displacement target is set in the first transition mode. The method may include determining if the current mode is hybrid, hydrostatic, or a no-propulsion mode and if the selected mode is hybrid, hydrostatic, or no-propulsion. The engine-pump displacement target may be matched to a system consumption and an accumulator isolation valve closed when an engine-pump output matches the system consumption in the first transition mode. The method may include entering a second transition mode if the selected mode is hybrid and the current mode is hydrostatic. A method of configuring a propulsion mode from hybrid to hydrostatic includes configuring a drive motor displacement target to full displacement, matching a pump displacement to system consumption, and closing an accumulator isolation valve when a pump flow output matches the system consumption.
