An electrified vehicle includes a multi-phase electric machine having a rotor with a number of magnetic pole pairs and secured for rotation with an output shaft. A parking gear secured for rotation with the output shaft has external teeth configured to selectively engage a parking pawl. The parking gear, the rotor, and the output shaft include complementary angular alignment features to angularly orient the parking gear relative to the rotor in an angular position offset by an index angle from one of the magnetic poles of the rotor such that occurrences of the parking pawl being engaged with the parking gear during dead time periods of an inverter powering the electric machine are reduced or eliminated.
