Abstract
A park lock for an automatic transmission includes a primary actuator that is operable to move a primary rod such that the primary rod rotates a pawl and selectively meshes a tooth of the pawl with teeth of a park wheel. A secondary actuator is operable to move a secondary rod. A distal end portion of the secondary rod holds the tooth of the pawl in meshing with the teeth of the park wheel in a park configuration. The distal end portion of the secondary rod blocks the tooth of the pawl from meshing with the teeth of the park wheel in a drive configuration. A related automatic transmission is also provided.
