Manual shifter reverse lockout mechanism with vibration isolation system

A vibration isolation system for a reverse lockout mechanism in a manual shifter for a motor vehicle, comprising:

• a shifter housing;
• a shaft pivotally retained in the housing and having an upper end adapted to receive a shift knob, wherein the shaft has a barrel proximate to the housing;
• a lockout skirt slidably mounted over the shaft between upper and lower positions, wherein the lockout skirt has an internal cavity receiving the barrel, wherein the lockout skirt has a shoulder extending radially outward, and wherein the housing includes a stop block such that the shaft is prevented from pivoting to a reverse gear position when the lockout skirt is in the lower position and is free to move to the reverse gear position when the lockout skirt is in the upper position;
• a spring retained on the shaft and biasing the lockout skirt toward the lower position;
• and
• a plurality of lubricated O-rings on the shaft defining sliding interfaces radially disposed between the lockout skirt and the shaft and between the lockout skirt and the barrel preventing radial contact of the shaft with the lockout skirt and with the barrel, thereby isolating the lockout skirt and the barrel from vibrations of the shaft.
