Power Flow - Manual 1

In Manual 1, transmission drive is via the input shaft
to the forward clutch cylinder. The elements of the
trans-mission function as follows;

•

The C2 clutch is engaged to drive the forward sun
gear, via the 3-4 OWC.

•

The B2 band is engaged to hold the planetary gear
carrier stationary.

•

The forward sun gear drives the short pinion anti-
clockwise.

•

The short pinion drives the long pinion clockwise.

•

The long pinion rotating about its axis drives the
inter-nal ring gear and the output shaft in a clockwise
or forward direction.

•

The C4 clutch provides engine braking through the
3-4 OWC on overrun.

Control

To maintain this arrangement in the steady state sole-
noids 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 en-
gages the C2 clutch.

•

Lo-1st (line pressure) oil is routed through the 1-2
shift valve to the C4 clutch, and to the inner apply
area of the rear servo piston for B2 band application.

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.

Control

To maintain this arrangement in the steady state sole-
noids 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 en-
gages the C2 clutch.
