Abstract: A transmission is provided with a park pawl moveable around an axis and positioned over a park gear. An actuator assembly is provided for pushing the park pawl against the effect of a return spring in a blocked position thus blocking the park gear. In order to provide a transmission in which the risk of an erroneous engagement of the park pawl due to a broken spring is avoided, means, such as a mechanical coupling, are provided for mechanically coupling the park pawl to the actuator when the park pawl is in unblocked position. Due to this mechanical coupling, the park pawl is retained in the unblocked position and prevented from falling into the park gear even if the return spring breaks.
