An 8-speed automatic gearbox will be introduced for the first time at Volkswagen in the Touareg 2011.

The 8-speed automatic gearbox 0C8 is a further development of the 6-speed automatic gearbox 09D from the Japanese gearbox company AISIN AW CO LTD. Together with the extensive know-how provided by the Volkswagen engineers, success has been achieved in adapting the gearbox to the Volkswagen technologies’ increased requirements.

Thanks to the eight forward gears and the closer gear ratio steps, consumption values and emission values have been reduced even further in comparison with the automatic gearbox 09D. Once again, the eight forward gears are made possible using the tried-and-tested Lepelletier gear set concept.

The automatic gearbox 0C8 can be supplied together with the start/stop system, and is also designed for the hybrid drive. All engine variants in the Touareg are available exclusively with this gearbox.

The self-study programme describes the design and function of the 8-speed automatic gearbox 0C8 as it is installed in the Touareg. The function and design of those components which are required in the gearbox for the start/stop system and the hybrid drive are described.
