THIRD GEAR POWERFLOW
Torque from the torque converter is increased via
the drive shaft (25) and the center planetary gearset
and transferred to the output shaft (26) (Fig. 6) and
(Fig. 7).
Front Planetary Gear Set
The planetary carrier (13) and sun gear (21) are
connected via the engaged multiple-disc clutch K1
(7). The planetary gearset is therefore locked and
turns as a closed unit at the input speed due to the
mechanical connection of the annulus gear (8) and
drive shaft (25).
