7G Tronic Automatic Transmission
Details & Technology
The new 7G-TRONIC PLUS 7-speed automatic transmission with fully integrated,
electrohydraulic transmission control has been adapted to specific van requirements in terms
of reduced fuel consumption/emissions and smoother shifting.
Power is transferred to the wheels via a torque converter with integrated lockup clutch. The
lockup clutch minimizes power loss or slip across the torque converter and can engage in all
gears, depending on engine speed and load. This system allows upshifts to be performed
smoothly and almost instantaneously.
There are 7 forward gears and 1 reverse gear available. The new automatic transmission's
fifth forward gear is configured for direct drive, while gears six and seven have longer ratios to
reduce the engine speed and thus cut fuel consumption.
