Abstract: A motor vehicle transmission includes a housing, a parking gear and a retainer. The housing has a support wall. The parking gear is pivotally coupled to the support wall of the housing by a pivot pin. The pivot pin has an end that protrudes outwardly from the support wall. The retainer has a proximal end fixedly secured to the support wall and a distal end contacting the end of the pivot pin to retain the pivot pin in the support wall. The retainer is elastically deformed upon securing the proximal end to the support wall and continuously axially biasing the pivot pin toward the housing. Additionally, the distal end is shaped to retain the end of the pivot pin, thereby axially constraining the pivot pin relative to the housing and, at the same time, preventing rotation of the retainer about the fastener.

Abstract: A semi-permanent retainer mechanism for securing a shaft within a component by forming a semi-permanent ridge on the shaft is provided. The mechanism includes a ring made from a heat shrinkable polymer that will heat shrink into a radial groove on the shaft. The heat shrinkable polymer of the ring has a release temperature wherein the ring shrinks in size when heated to a temperature above the release temperature. The ring has a pre-release size that is larger than the radial groove and a release size that is smaller than the outer circumference of the shaft.
