Kiwi inventor Bill Martin has developed a gearbox .
The last big breakthrough in automatic gearboxes was in 1928 with synchromesh.
The Zeroshift transmission can shift gears in zero seconds and do it seamlessly by using electronically controlled actuators and an automated single dry clutch. These actuators also can be powered by either air or hydraulic pressure, which greatly expands the type of vehicle applications.
The secret behind the Zeroshift concept is the elimination synchro rings, which are replaced bydog clutches. These dog clutches automatically upshift and downshift the transmission
