Front clutch
When the shift is in 3rd gear in the "D" range, the rear clutch and the
front clutch are actuated. and other elements are all released.
Therefore, driving force is transmitted from the forward sun gear and
the reverse sun gear.
Since the short and long pinions rotate in the same direction, they are
placed under a locked condition, causing the planetary gear set to
rotate as one unit.
l
This means that the engine rotation is directly connected, setting the
ratio between the input to and output from the planetary gear set to
1 : 1. The reduction ratio of 3rd gear is achieved in this way.
Note that the end clutch is aotuated to provide for smooth shift
change to 4th gear.
