the transmission.
The stator increases the torque up to the clutch
point (approx. 90
% speed difference between the
impeller and the turbine wheel).
In order to increase the efficiency of the automatic
transmission, the torque converter is also equipped
with a hydraulically activated TCC
The TCC is applied with slip to ensure soft
engagement.

When the TCC is engaged, the torque is '..
transmitted directly from the crankshaft via the

The drive is transmitted from the torque converter
(I) on the one hand to the transmission input shaft
(2) and via the 1st-3rd gear clutch (3) to the small
sun gear
(4), and on the other hand from the
transmission input shaft via the
3rdl4th gear clutch
(17) to the planet gear carrier (6).
As the drive is transmitted to two components
simultaneously, there are no relative movements
within the planetary
gearset. The planetary gearset
rotates as a complete unit.
N0TE:The 2nd-4th gear brake (1 3) remains
engaged, but the large sun gear
(I 5) can rotate in
the same direction of rotation as the output from
the engine by means of the 2nd gear one-way
clutch
(14), as a result of which the 2nd-4th gear
brake has no influence on the transmission ratio.
The Annulus (1
0) is fixedly connected to the output
wheel of the planetary
gearset and drives the
intermediate gear stage (1 1
) in the opposite
direction of rotation to the output from the engine.
The intermediate gear stage drives the differential
assembly (12) in the same direction of rotation as
the output from the engine.
