7G-TRONIC PLUS Automatic Transmission

The 7-speed automatic transmission transfers engine power to the road with even greater ease and boasts a winning combination of smoother gear-shifting, lower fuel consumption and reduced emissions.

7G-TRONIC PLUS is the latest version of the successful 7-speed automatic transmission from Mercedes-Benz. It has undergone extensive modifications in comparison to its predecessor in the areas of smooth gear-changing, fuel efficiency and reduced CO2 emissions. The engines from Mercedes-Benz supply the power and 7G-TRONIC PLUS applies it to the road with maximum efficiency.

Powerful and Efficient.



Detailed information


Changes may have been made since these images and films were produced.

7G-TRONIC PLUS has been modified and improved in many aspects in comparison to its predecessor.


The 7G-TRONIC PLUS transmission was systematically refined and improved in many points over its predecessor. A newly-developed hydraulic circulation and an optimized torque converter characteristic line enhance the starting-off performance, the effectiveness and also smoother operation of the torque converter lockup clutch significantly. The new automatic transmission oil (FE-ATF (Fuel Economy – Automatic Transmission fluid) with a modified package of additives, offers longer useful life with unchanging good lubrication and cooling properties.


In the transmission itself materials and disk linings were adapted, and numerous changes made to the geometry, in order to achieve optimum oil management. The improved integrated electrohydraulic transmission control unit and the frictional reductions in conjunction with optimized engine and transmission software lead to better shifting dynamics and quality. The entire basic transmission was also consistently further developed.


All these small measures add up to significant advantages in terms of improved motoring enjoyment, comfort and a consumption reduction of up to 7%.
