Assembly with metal casting and polymeric member and transmission shift mechanism

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 polymeric member having an exterior engagement surface engaged with said transmission shift mechanism;
• and
• a unitary metal casting, said metal casting engaged with said polymeric member and relatively moveably capturing said polymeric member on said metal casting, said casting being secured to said transmission shift mechanism, said polymeric member including an opening defining a rotational axis of said polymeric member and said opening includes a central cylindrical portion and first and second end portions having diameters greater than said central cylindrical portion, said first and second end portions being disposed proximate opposite ends of said opening, said metal casting substantially filling said central cylindrical portion and said first and second end portions of said opening thereby rotationally disposing and axially capturing said polymeric member on said metal casting.
