The driving force from the input shaft (1) is transmitted
to the rear sun gear (5) and reverse & high clutch drum.
As the low clutch (14) is engaged, the movement of the
rear internal gear (7) is restricted. Since the low one-
way clutch (16) acts at the same time,
counterclockwise rotations of the rear internal gear (7)
are locked. As a result, the driving force transmitted to
the rear sun gear (5) rotates the rear planetary carrier
(13) clockwise, then the rotation speed is decreased
and multiple forces is transmitted to the output shaft (8). When decelerating, the rotating speed of the rear
planetary carrier (13) (rear pinion gear [6]) is higher
than that of the rear sun gear (5) and the rear internal
gear (7) attempts to rotate clockwise. At this time, the
low one-way clutch (16) does not act but races, and
therefore the rear internal gear (7) rotates clockwise.
The reverse torque from the driving shaft is not
transmitted to the engine side and the engine brake
does not act.

17. Parking pawl
The driving force from the input shaft (1) is transmitted
to the rear sun gear (5) and reverse & high clutch drum.
As in the case of the 1st gear, the low clutch (14) is
engaged and the movement of the rear internal gear (7)
is restricted. Since the 2-4 brake is engaged (10), the
front sun gear (4) is fixed. As a result, movement of the
rear internal gear (7) is restricted, and the driving force
transmitted to the rear sun gear (5) rotates the rear
planetary carrier (13) clockwise. The rotating speed of
the rear planetary carrier (13) is higher than in 1st gear as the rear internal gear (7) rotates. When decelerating,
the engine brake is applied.

The driving force from the input shaft (1) is transmitted
to the rear sun gear (5) and reverse & high clutch drum.
Since the 2-4 brake (10) is engaged, the front sun gear
(4) is fixed. In addition to this the high clutch (11) is
engaged. As a result, the front pinion gear (6) rotates
itself together with other gears clockwise. This rotation
increases the speed of rotation of the front internal gear
(12) and is transmitted to the output shaft (8).
