Abstract: A hybrid transmission includes a transmission having a selectable clutch device effective when engaged to mechanically couple an internal combustion engine to a first axle at a fixed engine speed to axle speed ratio. A method for starting the engine includes executing an engine start event including spinning and fueling the engine such that an engine speed to axle speed ratio exceeds the fixed engine speed to axle speed ratio, and engaging said selectable clutch device after the engine speed to axle speed ratio exceeds the fixed engine speed to axle speed ratio.
