>
E63, E64 from 09/2007
Option 205 "Automatic transmission" is discontinued.
On E63, E64 vehicles, only option 2TB "Sport automatic transmission" is available. Depending on the model
concerned, the "sport automatic transmission" is either standard or special equipment.
The sport automatic transmission differs from the automatic transmission as follows:
-
Gearshift paddles on steering wheel
-
SPORT button in the selector lever trim
-
Sport program also possible in selector lever position "D"
-
Separate gear selector switch (GWS)
So as to be compatible with the engines with higher torques, the automatic transmissions are designed with different
strengths. The automatic transmissions thus differ, e.g. through different torque converters.
Depending on the engine fitted, the following 6-speed automatic transmissions are fitted:
-
GA6HP19Z (designed for maximum torque of 400 Nm)
-
GA6HP19Z TU (designed for maximum torque of 400 Nm)
-
GA6HP26Z (designed for maximum torque of 600 Nm)
-
GA6HP26Z TU (designed for maximum torque of 650 Nm)
-
GA6HP32Z (designed for maximum torque of 750 Nm)
(technical updates, e.g. of transmissions, are indicated with the letters "TU".)
The automatic transmission requires 5 multi-plate clutches to shift between the 6 gears: 3 input clutches and
2 brake clutches.
