from the front larger 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

counterclockwise direction. The front planetary
gear carrier and the shaft drive pinion rotate in
counterclockwise direction with the rear ring gear
as one unit. The final drive rotates in the clockwise

Engine braking:
The power is transferred directly to the
transmission input shaft without one-way clutch
involvement. Engine braking is thus applied.

Shift solenoids S1, S2, S3, S4 and S5 are located
in the control valve assembly on the front of the
transmission.
Function
The shift solenoid valves are actuated by the TCM
TCM. The shift solenoid valves S1 and S4 are fully
open when de-energized. The shift solenoid valves
S2, S3, and S5 are fully closed when de-energized.
They control gearshifting, while the TCM decides
which gear should be engaged by activating the
shift solenoid valves in different combinations.

The valve actuates the torque converter clutch as
well as the reverse gear brake (B3) and 2nd - 5th
gear brake (B2). The PWM control achieves
smooth engagement of the gears. The two brakes
are actuated in 1st and 2nd gear to guarantee
engine braking.
The valve also actuates the torque converter in
such a way that is works in three positions: 'open',
'controlled looping (slip lock-up mode)', and 'locked
(full lock-up mode)'. The hydraulic function of the
valve is linear.
In lockup mode the TCC is closed. The impeller
and the turbine of the torque converter are friction
locked. The engine torque acts directly on the
transmission input shaft. Fuel consumption is
reduced due to a reduction in the torque converter
pump losses.
In slip lock-up mode, slip in the TCC is permitted
in order to improve driving comfort. The hydraulic
pressure acting on the TCM varies in accordance
with the duty signal of the actuation signal
generated by the PWM for the TCC solenoid valve
for the TCC (SLU). The temperature of the
transmission fluid increases in slip mode.

The valve directly actuates the multi-plate brake
(B1) in 2nd - 4th gear as well as the clutch (C2) in
5th and reverse gear. The PWM control achieves
smooth engagement of the gears.
The hydraulic function of the valve is linear. The
hydraulic valve is controlled by means of the
varying current resulting from the current duty
cycle. The system pressure is low with a high duty
cycle, i.e. with high current intensity (approx. 1 A),
and vice versa.

The shift pressure increases to the maximum value
