Mitsubishi Fuso has introduced a double-clutch transmission in commercial vehicles. Known as the "Duonic", this double-clutch transmission combines automated driving with the advantages of a manual transmission.


The new double-clutch transmission for commercial vehicles drives like an automatic transmission, but unlike a fully automatic torque converter transmission, it makes for lower consumption figures and therefore lower exhaust emissions.

As with a fully automatic transmission it is a two-pedal system, there is an accelerator pedal, a brake pedal and a selector lever. The selector lever allows automatic or manual gearshift mode to be selected.

The M038S6 Duonic transmission has six forward gears and a reverse gear. The P-function ensures safe parking by preventing the vehicle from rolling away.



Duonic features a non-wearing wet clutch, which lowers maintenance costs by eliminating the need to replace worn clutch discs.

A creep function has been added to the wet clutch, as is usual for automatic transmission with a torque converter. This enables the vehicle’s speed to be easily controlled when moving slowly—for example when manoeuvring or in stop-and-go traffic—and hill-starts are also made easier.

If you suspect a problem with your gearbox or differential, Call Mayfair Gearbox and we will come and Collect your Vehicle *Nationwide*.


Our Gearbox Specialists have all the expertise needed to repair, replace and service Automated Manual Transmissions, so you can get safely back on the road and to work in no time.
