A gearshift sleeve is an internally toothed metal ring that sets the gear in the gearbox through a positive connection between the wheel attached to the shaft and the respective gear. The fork is operated via the shift lever and the shift linkage, this takes the shift sleeve with it and engages the gear.

In automobiles , the shift linkage is operated via the shift lever in the interior of a vehicle, and this then moves the shift fork inside the transmission. The sleeve is axially carried along by the fork, as a result of which the synchronizer ring adapts the speed of the respective gear to that of the shaft by means of friction via a cone. As soon as the speeds match, the shift sleeve slips almost effortlessly over the gear, creating the connection between the input and output shafts, and the flow of power is guaranteed.

A 5-speed transmission usually has three shift sleeves, one of which is always responsible for two gears (gear 1 and 2, gear 3 and 4, gear 5 and reverse). If this is moved from the middle position in one direction, the power flow for one gear, e.g. B. Gear 1, closed and in the other direction then gear 2. There is always only one pair of gears in the power flow, the rest of them run with no power.
