Abstract
A vehicle transmission includes a plurality of shift shafts that cooperate with a common neutral switch to control when range shifts occur. In one example, the plurality of shift shafts includes a first shift shaft, a second shift shaft, and a third shift shaft that is positioned between the first and second shift shafts. A plunger actuates the neutral switch in response to movement of the third shift shaft along an axis. A first switch pin is positioned between the first shift shaft and the plunger and a second switch pin is positioned between the second shift shaft and the plunger. The first and second switch pins move the plunger to actuate the neutral switch in response to axial movement of a respective one of the first and second shift shafts. Thus, each of the first, second, and third shifts shafts can actuate a single neutral switch by cooperating with a common plunger.
