LESSON 3: POWERTRAIN
The shift elements are engaged hydraulically. The transmission fluid pressure builds up between the cylinder and
the piston, pressing the clutches together.
The purpose of these shift elements is to carry out in-load shifts with no interruption to traction.
Multi-plate clutches forward, direct and overdrive supply power from the engine to the planetary gear train.
Multi-disc brakes intermediate and low/reverse press against the transmission housing in order to achieve a torque
reaction effect.
