Word forms: (plural) syncromesh gearboxes
( Automotive engineering : Vehicle components , Engine, transmission, and exhaust )
It is often claimed that a synchromesh gearbox requires less effort to change gears.
Before the synchromesh gearbox was introduced in the 1930s, every driver had to master the difficult task of double-declutching.
When the manufacturer advertises a car as having a synchromesh gearbox you cannot expect to have synchromesh on the first gear, and never on reverse.
