ABSTRACT:
A transmission control selector arm transmits movement of a gear shift lever to the manual valve of an automatic transmission through a shift mechanism that includes a tube, rotatably mounted and supported against displacement and having one end pivotably supporting the gear shift lever and a second end pivotably supporting the transmission control selector lever. A plunger is supported within the tube for axial displacement and defines, near one axial end, a hole, into which the gear shift lever is retained for rotation about the pivoted support on the tube. The selector lever is supported for movement about a second pivotal joint on the tube. A control selector position insert mounted on the tube defines multiple detent surfaces corresponding to the various positions among which the gear selector lever can be moved. These detent surfaces are located adjacent the selector lever. The lever and plunger are biased by a spring so that the selector lever moves axially away from the detent surfaces as the gear selector lever moves and returns into contact with the detent surfaces when manual control of the position of the gear shift lever is absent.
