A transmission parking lock has an actuating rod that is essentially translationally displaceable, which bears an actuating element, and with a locking lever that is essentially rotationally displaceable, bears a locking element For inserting the transmission parking lock through the displacement of the actuating rod, the locking lever is pivotable from a resting position of the same into a locked position in such a manner that the locking element engages in a recess of a gear wheel (8) allocated to a gear shaft, and with a device that withdraws the actuating element of the actuating rod in the resting position of the same from the locking lever.
