ABSTRACT:
A selector shaft return guide for a multiple speed automotive transmission includes a selector shaft for selecting the gear shift channel; a lever member rotatably fixed to the selector shaft; a holding member axially displaceable relative to the selector shaft and fixed rotatably to the casing; and a spring that forces the holding member against the lever. The lever member is formed with two tracks, offset angularly and having a depth that varies in a peripheral direction. Balls located in the tracks between the holding member and the lever member travel within the groove against the force produced by the spring that urges the selector shaft to return to the neutral position.
