Power transmission
In its basic design, the 6-gear automatic gearbox does not differ from other automatic gearboxes.
It consists of:
● the torque transformer with transformer bypass coupling,
● the ATF pump,
● a simple planetary gear set according to Simpson,
● a dual planetary gear set according to Ravigneaux,
● three multi-disc couplings,
● two multiple disc brakes and
● the control valve assembly.
Design of automatic gearbox
A novelty at Volkswagen is the external axle drive. From the drive shaft of the automatic gearbox,
the torque of the engine enters a transfer gearbox that is flanged onto the automatic gearbox.
In the transfer gearbox, the torque is divided into equal parts, or according to requirements,
to the drives of the front and rear axles.
