Abstract
A gear selector device for a transmission of a motor vehicle in which at least one gear wheeland one sliding sleeveare situated upon one transmission shaft. For axial displacement of the sliding sleeveupon the transmission shaft, a pressure-medium actuatable shifting deviceis used which is supplied with a control pressure medium through a holewithin the transmission shaft. When several such sliding sleevesare disposed upon such a transmission shaft, there results a higher total construction cost for the control pressure supply thereof. The object of the invention is a transmission shafthaving several sliding sleevesto reduce the total construction cost for the axial displacement of the sliding sleeves. To the end, it is provided that the shifting devicesof the sliding sleevescan be supplied independently of each other with a control pressure medium through one common pressure medium holein the transmission shaft
