(1) Power flow - Drive 2 and manual 2
In Drive 2 and Manual 2, transmission drive is via the input shaft and 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 anticlockwise.
- 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.
(2) Control
To maintain this arrangement in the steady state solenoids and valves are activated as
follows :
- Solenoids S1 and S2 are switched ON.
- The 1-2, 2-3, and 3-4 shift valves are held in their first gear positions by line 500 pressure.
- Drive (line pressure) oil from the manual valve engages
the C2 clutch.
