• an electric machine coupled to the dual clutch transmission;
• and
• a controller including executable instructions stored in non-transitory memory to request rotation of the electric machine in response to an indication that a first gear or a second gear is not engaged after the dual clutch transmission has been commanded to a park state.

A driveline operating method comprising:

• receiving a request to enter a vehicle park state where an output shaft of a transmission is held from rotating, and simultaneously commanding a first gear engaged and commanding a second gear engaged, the first gear coupled to a first layshaft and the second gear coupled to a second layshaft, in response to the request to enter the vehicle park state where the output shaft of the transmission is held from rotating;
• receiving an indication that the first gear or the second gear is not engaged, and rotating an electric machine coupled to the output shaft of the transmission in response to the indication that the first gear or the second gear is not engaged;
• receiving a request to exit the vehicle park state, and commanding the first gear or the second gear disengaged in response to the request to exit the vehicle park state;
• and
• receiving an indication that the first gear or the second gear is not disengaged after commanding the first gear or the second gear disengaged, and rotating the electric machine coupled to the output shaft of the transmission in response to the indication that the first gear or the second gear is not disengaged after commanding the first gear or the second gear disengaged.
