Abstract

An improved park lock rod assembly is provided for a park lock mechanism of a vehicle transmission wherein the park lock rod assembly includes a spring-loaded lock rod captured by a guide member. The guide member includes a first bulbous open slot that is generally L-shaped and receives one end of the lock rod, and another open slot spaced axially from the first open slot that receives another end of the lock rod. This slot configuration allows the rod to pivot relative to the guide member and seat within the second open slot, which permits ready assembly of the lock rod to the guide member. The park lock rod assembly may be manually assembled without the need for crimping or other fasteners. Further, the rod is grooved to cooperate with keyhole shapes provided in the open slots wherein the groove and slot configurations permit the rod to be assembled into the guide member while preventing separation during reciprocating movement of the lock rod.
