Quizplus · Accepted Answer

Technician A is correct because in a conventional transmission, the speed gears do indeed freewheel around the mainshaft until they are locked to it by the synchronizer. Technician B is incorrect because the speed gears do not slide away from the counter gears; they remain in constant mesh with the counter gears and are moved into engagement by the action of the synchronizers, not by moving in or out of mesh.
