ABSTRACT:
A transmission shift mechanism for use with a vehicle transmission. The transmission shift mechanism includes a user-operated selector and a sub-assembly operably disposed between said user-operated selector and the vehicle transmission. The sub-assembly includes a torque-transfer member having a first portion and a second portion wherein the first portion is pivotally secured to the transmission shift mechanism about a pivot axis and the second portion defines a section of a substantially spherical surface which is engageably disposed within a non-linear camming slot defined by the transmission shift section. The torque-transfer member takes the form of a molded polymeric body with a sheet metal insert disposed within the molded polymeric body. The second portion of the torque-transfer member may include flats to reduce the volume of polymeric material required in the manufacture of the member. A method of manufacturing such a torque-transfer member or crank arm is also disclosed.
