    Synchromesh gearbox uses synchronizer instead of sliding dog clutches to affect the ratio change. The synchromesh gearbox is similar to the constant-mesh gearbox, but the synchromesh gearbox is provided with a synchronizer, the device by which two gears to be engaged are first brought into frictional contact which equalizes their speed, afterward they are engaged smoothly.
