A single piece spring member which replaces the normal insert and spread spring ring arrangements, under the influence of the coupling sleeve moving toward a gear, biases the baulk ring against the gear to induce an initial stage of synchronization, until the coupling sleeve splines slip past the spring, whereafter engagement of chamfers on the coupling sleeve splines and with those on the teeth formed on the baulk ring, completes the synchronization and permits the coupling sleeve to move into engagement with teeth on the gear.
