The transaxle features three clutches, five brakes,
and two one-way clutches.
The clutches are designed as multi-plate clutches.
There are four multi-plate brakes (B1, B2, B3, B5)
and one band brake (B4).
Tasks of clutches and brakes
• 1st-5th gear clutch (C1) : Connects the input
side with the ring gear.
• 5th gear and reverse clutch (C2) : Connects
the input side with the sun gear.
• 4th and 5th gear clutch (C3) : Connects the
sun gear with the front planetary gear carriers
on the output side. •
2nd-4th gear brake (B1) : Locks the sun gear
on the input side.
• 2nd-5th gear brake (B2) : Locks the rotational
movement of the sun gear on the input side in
a counterclockwise direction.
• Reverse gear brake (B3) and 1st gear brake
in select-shift mode : Locks the ring gear on
the input side.
• 3rd gear brake (B4) (band brake) : Locks the
two sun gears on the output side.
• 1st and 2nd gear and reverse gear brake
(B5) : Locks the rear planetary gear carriers on
the output side.

The transmission input shaft rotates in the
clockwise direction. All clutches and brakes on the
input side are deactivated and no power is
transmitted to the planetary gear sets.
No force is transferred to the output shaft. The
brake B5 (2) locks the rear planetary gear carrier
on the output side. The parking lock (1) is not
activated. Since the transaxle input shaft is not
positively connected with the input side, the vehicle
will start to roll away if it is on an incline. The brake B5 is activated both in 'P' and in 'N'
position to reduce the cut-in pressure that
otherwise occurs if several brakes and clutches
are activated simultaneously when the selector
lever is moved to 'D' or 'R' position. Since the brake
B5 is activated both in first and second as well as
in reverse gear, this method reduces the total
number of transient effects.

Input shaft:
The transmission input shaft rotates in the
clockwise direction. Clutch C1 (1) joins the
transaxle input shaft with the ring gear, which
rotates in clockwise direction. The rear planetary
gear set rotates in the clockwise direction. The
front larger planetary gear set rotates clockwise
with the rear planetary gear set as a single unit.
The front smaller planetary gear set rotates in the
clockwise direction. The front annular gear rotates
counterclockwise. One-way clutch F2 (2) blocks
the front annular gear clockwise rotation.
The front and rear planetary gear carriers are
turned clockwise because of the reactive forces
from the small gear. The primary idler gear rotates
clockwise with the front and rear planetary gear
carriers as one unit.
Output shaft:
The secondary idler gear rotates counterclockwise.
The front annular gear rotates counterclockwise
with the secondary idler gear as a single unit.The front planetary gear set rotates in the clockwise
direction. The sun gear rotates clockwise.
The rear planetary gear set rotates
counterclockwise. Brake B5 (3) prevents rotation
of the rear planetary gear carrier. The rear annular
gear rotates counterclockwise. The front planetary
gear carrier and the final drive pinion rotate
counterclockwise with the rear annular gear as one
unit. The final drive rotates in the clockwise
direction.
Engine braking:
The 1st gear has no engine braking function
because the power flow is interrupted by the
one-way clutch F2 rotating against the locking
direction.
The brake B3 is additionally activated in select-shift
mode to guarantee engine braking.
