A gear selector device for a transmission of a motor vehicle in which at least one gear wheel 2, 3 and one sliding sleeve 4 are situated upon one transmission shaft 1 . For axial displacement of the sliding sleeve 4 upon the transmission shaft 1 , a pressure-medium actuatable shifting device 45 is used which is supplied with a control pressure medium through a hole 10 within the transmission shaft 1 . When several such sliding sleeves 4, 20 are disposed upon such a transmission shaft 1 , there results a higher total construction cost for the control pressure supply thereof. The object of the invention is a transmission shaft 1 having several sliding sleeves 4, 20 to reduce the total construction cost for the axial displacement of the sliding sleeves 4, 20 . To the end, it is provided that the shifting devices 45, 46 of the sliding sleeves 4, 20 can be supplied independently of each other with a control pressure medium through one common pressure medium hole 6 in the transmission shaft 1.
