Third generation of Global FWD 6-speed Automatic Transmission (GF6)

摘要

The next generation of fuel efficient FWD 6-speed Automatic Transmissions (GF6 Gen III) has been launched in North America in September 2013 in the Chevrolet Malibu and will be introduced in Europe at the end of 2014 for Opel/Vauxhall. With a torque capacity range from 175 Nm to 400 Nm this transmission family is an optimal solution for the majority of global applications, providing high efficiency, short shift times and high shift quality. Improved fuel efficiency can be expected up to 2% compared to 2nd transmission generation. This additional reduction of fuel consumption has been achieved by transmission improvements, including the introduction of a new off-axis binary oil pump, variable lube flow and reduction of oil level. An external accumulator has been implemented to enable Stop-Start capability providing additional fuel economy.
