Power Flow - Drive 1
In Drive 1, transmission drive is via the input shaft to
the forward clutch cylinder. The elements of the
transmission function as follows :
•
The C2 clutch is engaged to drive the forward sun
gear via the 3-4 OWC.
•
The forward sun gear drives the short pinion anti-
clockwise.
•
The short pinion drives the long pinion clockwise.
•
The 1-2 OWC prevents the planetary gear carrier
from rotating under reaction force and the long pinion
rotates on its axis driving the internal ring gear and
output shaft in a clockwise or forward direction.
•
There is no engine braking on overrun.
