In today's automotive transmission designs, technologies are evolving rapidly as the world's leading manufacturers seek better fuel economy, lower emissions and higher performance. The largest current change is in the generation of transmission's known as Automated Manual Transmissions (AMT's). Our QISS™ transmission is an improved form of AMT's.

For some years now, automatically shifted manual transmissions have been on the market. They automate the gear shifting components to make it more like an automatic transmission while using the mechanically more efficient, lighter, cheaper and smaller components from a manual transmission. However, to make a gearshift smoother in AMT's, the engine power output has to be interrupted (torque interrupt) making the gearshift quite jerky when compared to a conventional automatic transmission. QISS™ is a solution!

The New Generation of Automated Manual Transmissions (AMT's)

Our QISS™ system delivers improvements to the new generation of AMT's where the gears can be shifted smoothly without interrupting the engine's power output (full power shift). The smoothness of the gear shift and the ability to deliver "full power shift" are the major advantage of QISS™ over other AMTs. A further benefit of this Next Generation AMT is that the gears can be shifted fully automatically, or semi-automatically, or even manually, using manual gearbox components with minor changes to mass production tooling. The car maker can simply choose the control system to manage the transmission in whatever way suits their particular need for any specific product.

The QISS™ Transmission

The QISS™ transmission retains the basic manual (layshaft) transmission layout but uses QISS™ as a launch device and replaces the conventional clutch or torque converter. QISS™ uses less axial force and travel for actuating the clutch and uses "cone clutch friction plates". No hydraulic pump system is required. We see QISS™ replacing conventional wet and dry clutch actuation systems.
