The driving force from the input shaft (1) is transmitted
to the rear sun gear (5) and reverse & high clutch drum.
In the R range, the reverse clutch (9) is engaged and
the driving force is transmitted to the front sun gear (4)
and rotates it clockwise. The low & reverse brake (15)
is also engaged and the front planetary carrier (2) is
fixed so that the front pinion gear (3) does not rotate
clockwise, but can rotate counterclockwise. As a result,
the output shaft (8) rotates counterclockwise and the
vehicle goes backwards.
