Circuit assembly with parking lock and method for actuating the same

The circuit arrangement (30) has a shifting clutch arrangement (34), by which a gear stage of a clutch gear (16) is engaged or disengaged. An actuator arrangement (40) is coupled over a power transmission unit (46) with the shifting clutch arrangement. The power transmission unit has a decoupling unit (58) which is formed to enable the actuator arrangement in a parking lock position (P), even when the shifting clutch arrangement is blocked. An independent claim is included for a method for actuating a parking lock arrangement by an actuator arrangement, particularly by a circuit arrangement.
