Abstract:
1. A transmission shift mechanism for use with a vehicle transmission comprising: a user-operated selector; and a sub-assembly operably disposed between said user-operated selector and the vehicle transmission, said sub-assembly including: a torque-transfer member having a first portion and a second portion, said first portion being pivotally secured to said transmission shift mechanism about a pivot axis, said second portion defining a section of a substantially spherical surface, said spherical surface section being engageably disposed within a non-linear camming slot defined by said transmission shift mechanism, said torque-transfer member being formed by a molded polymeric body having a sheet metal insert disposed therein, said first portion having a non-circular opening extending therethrough in a direction parallel to said pivot axis, said opening comprising a plurality of corners each having a small depression or corner relief therein, said opening receiving a projection to thereby pivotally couple said first portion with said transmission shift mechanism with said sheet metal insert in direct force transmitting engagement with said projection, said opening forming outer perimeters on opposing first and second sides of said first portion, each of said outer perimeters defining a molded beveled edge defined by said polymeric body, wherein said projection is configured to be received in said opening from either of the first side or the second side.
