The gear selector lever and the manual selector spool
valve are in the D position. Engine torque is transmitted
from the torque converter turbine shaft to ring gear 1 of
the single web planetary gear train and the outer plate
carrier of clutch E.
Ring gear 1 drives the planetary gears which rotate
around sunwheel 1. This drives the planetary gear carrier
1 and also the outer plate carrier of clutch A and the

The gear selector lever and the manual selector spool
valve are in the D position. Engine torque is transmitted
from the torque converter turbine shaft to ring gear 1 of
the single web planetary gear train and the outer plate
carrier of clutch E.
Clutches A and B are released, removing the effect of
the single web planetary gear train.
Clutch brake C is applied which locks sunwheel 2 to
the transmission housing.
Clutch E is engaged and drives the double web
planetary gear carrier. This causes the long...

SELECTOR POSITION SWITCH
The Mechatronic valve block contains a position switch
which is mechanically connected to the selector spool
valve. The selector spool valve is connected by a
selector shaft to the selector lever via a Bowden selector
cable.
The signals from the position switch are used by the
TCM to determine the P, R, N or D selection made by
the driver.

The transmission cooler is integrated into the left hand
end tank of the engine cooling radiator. The transmission
fluid is cooled by the temperature differential between
the transmission fluid and the engine coolant and also
by airflow over cooling fins on the end tank.
Fluid is supplied from the transmission fluid pump into
the lower connection of the cooler. After...
