When the 1st gear is selected, the underdrive clutch,
the one-way clutch (OWC-L), the low-reverse brake*,
the reduction brake and the one-way clutch (OWC-
D) are participating. The driving force from the input
shaft is transmitted to the underdrive sun gear via the
underdrive clutch. The driving force transmitted to
the underdrive sun gear via the output pinion turns
the low reverse annulus gear clockwise and at the
same time turns the output planetary carrier anti-
clockwise with the fashion that the output pinion
revolves around the underdrive sun gear. However,
since the one-way clutch (OWC-L) and the low-
reverse brake* are engaged at this time, the low-
reverse annulus gear is locked and the output plane-
tary carrier only rotates anti-clockwise. This driving
force turns the direct pinion anti-clockwise via the
direct annulus gear. Since the direct sun gear is

locked by the one-way clutch, the direct planetary
carrier rotates anti-clockwise with the fashion that the
direct pinion revolves around the direct sun gear to
obtain reduction ratio of the first gear. Since the out-
put planetary carrier is connected to the output annu-
lus gear, the overdrive pinion gear is driven at the
same time. However, since the overdrive planetary
carrier is locked by the one-way clutch (OWC-L) and
the reverse sun gear is free to rotate, it runs idle and
has no effect on the rotation of the output planetary
carrier.
NOTE: *: The low-reverse brake is activated only
when the vehicle is stationary (10 km/h or less) and
in the sport mode.

When the 2nd gear is selected, the underdrive
clutch, the second brake, the reduction brake and the
one-way clutch (OWC-D) are participating. The sec-
ond brake is operated under the first gear condition,
the reverse sun gear is locked and the driving force
from the output annulus gear turns the overdrive
planetary carrier anti-clockwise with the fashion that
the overdrive pinion revolves around the reverse sun
gear. Since the overdrive planetary carrier is con-
nected with the low-reverse annulus gear, the low-

reverse annulus gear also rotates anti-clockwise.
This rotation of the low-reverse annulus gear is
transmitted to the direct annulus gear via the output
pinion, however, since the elements of the direct
planetary gear are the same as that of the first gear,
rotation amount of the low-reverse annulus gear is
added to the rotation of the output planetary carrier to
obtain the reduction ratio of the second gear.

When the 3rd gear is selected, the underdrive clutch,
the overdrive clutch, the reduction brake and the
one-way clutch (OWC-D) are participating. Since the
overdrive clutch connects the input shaft with the
overdrive planetary carrier and the low reverse annu-
lus gear, the rotation speed of the underdrive sun
gear that is connected with the input shaft by the
underdrive clutch and the rotation speed of the low-
reverse annulus gear become equal. Under this con-

dition, the planetary gear set is locked and rotates as
one body to transmit the driving force to the direct
annulus gear. The operation of the direct planetary
carrier elements is the same as the first gear, there-
fore, the reduction ratio of the third gear is obtained
by the configuration that the planetary gear set
rotates as one body under locked condition.

When the 4th gear is selected, the underdrive clutch,
the overdrive clutch and the direct clutch are partici-
pating. The operating condition of input shaft ele-
ments is the same as that of the third gear, where the
planetary gear set is locked to rotate as one body.
The driving force input to the output planetary carrier
is transmitted from the direct annulus gear con-

nected with the output planetary carrier, via the direct
pinion, to the direct sun gear and turns it clockwise.
On the other hand, since the direct sun gear is con-
nected with the direct planetary carrier by the direct
clutch, they rotate anti-clockwise as one body to
obtain the reduction ratio of the fourth gear.

When the 5th gear is selected, the overdrive clutch,
the direct clutch and the second brake are participat-
ing. The driving force of the input shaft is transmitted
to the overdrive planetary carrier via the reverse
clutch. On the other hand, since the reverse sun gear
is locked by the second brake, rotation amount of the
overdrive pinion that revolves around the reverse
sun gear is added to the rotation of the overdrive
planetary carrier and the resultant rotation is trans-

mitted to the output annulus gear. This driving force
is then transmitted to the output planetary carrier that
is connected to the overdrive planetary carrier and
the direct annulus gear. Since the operating ele-
ments of the direct planetary carrier are the same as
that of the fourth gear, the reduction ratio of the fifth
gear is obtained by the revolution of the overdrive
pinion.

When the reverse gear is selected, the reverse
clutch, the low-reverse brake and the reduction
brake are participation. The driving force of the input
shaft is transmitted to the reverse sun gear via the
reverse clutch. On the other hand, since the over-
drive planetary carrier is locked by the low-reverse
brake, the driving force of the reverse sun gear is
transmitted to the output annulus gear via the over-
drive pinion as the clockwise rotating force. This driv-
ing force is then transmitted to the direct annulus
gear via the output planetary carrier. Since the direct

sun gear is locked by the reduction brake, rotation
amount of the direct pinion that revolves around the
direct sun gear is added to rotate the direct planetary
carrier clockwise. Thus the reduction ratio of reverse
gear is obtained. At this time, the output pinion is
driven by the output planetary carrier, however, since
the underdrive sun gear is free to rotate, it runs idle
and has no effect on the rotation of the output plane-
tary carrier.

In parking and neutral, all of the clutches are disen-

shift to 1st gear or reverse, the low-reverse brake
and reduction brake is operational.
