General:

• The ZF 6HP26 automatic transmission has been developed for vehicles with an engine torque of up to 600
  Newton-metres (Nm ).
• To match the installed position of the engine, the automatic transmission is also arranged longitudinally.
• It uses the planetary gear train principle, with hydraulic-electronic control; the hydraulic and electronic
  control units form a composite element that is installed as a single unit inside the automatic
  transmission and referred to as “Mechatronik”.
• A new feature is decoupling of the transmission when the vehicle is at a standstill, that is to say
  instead of the engine remaining connected to the converter and the vehicle being prevented from moving by
  applying the brake, the converter is disconnected and only a minimum rotating load remains. This has the effect
  of further reducing fuel consumption. The electronic transmission control uses a newly developed shift strategy
• For this, please refer to the separate functional description.

The 6HP26 automatic transmission is about 13 % lighter than the previous 5-speed unit, accelerates 5 %
faster and uses about 7 % less fuel.
It also contains fewer components:
o 5-speed transmission app. 660 parts
o 6-speed transmission app. 470 parts
The 6-speed automatic transmission is 5 centimetres shorter than the 5-speed transmission.
Engine power reaches the transmission via a hydrodynamic torque converter with integral converter lock-up
clutch.
The input torque limits are:
6HP19 max. torque: 420 Nm
6HP26 max. torque: 600 Nm
6HP32 max. torque: 750 Nm
