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 applied to drive the forward sun
gear.

•

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

•

The short pinion drives the long pinion clockwise.

•

The B1 band is applied holding the reverse sun
gear stationary therefore the long pinion walks
around the reverse sun gear taking the internal ring
gear and output shaft with it in a clockwise or
forward direction.

•

The C4 clutch is applied to bypass the 3-4 OWC
and provide engine braking on overrun.

Control

To maintain this arrangement in the steady state sole-
noids and valves are activated as follows;

•

Solenoid S1 is switched OFF. S2 is switched ON.

•

Drive (line pressure) oil from the manual valve en-
gages the C2 clutch.

•

When S1 switches OFF, S1 oil pressure, which is
derived from line 500 pressure, moves the 3-4 shift
valve to the left. At the same time S1 oil is directed
to the 1-2 shift valve which moves the valve to the
second gear position.

•

2nd oil (line pressure) from the 1-2 shift valve is di-
rected to the band apply regulator valve, and to
the 2-3 shift valve.

•

The band apply feed regulator valve supplies 2nd
oil (regulated to line pressure multiplied by the valve
ratio) to the Band Apply Feed (BAF) circuit.

•

Band apply feed oil is directed to;

- The outer apply area of the front servo

- The 1-2 shift valve to provide an exhaust port

when the transmission is shifted to first gear

- The 3-4 shift valve for use when the transmission

is shifted into fourth gear

•

Drive (line pressure) is routed through the 3-4 shift
valve to apply the C4 clutch.

Power Flow - Drive 3 and Manual 3

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.

•

The C1 clutch is engaged to drive the planet carrier.

•

The short pinion drives the long pinion clockwise.

•

The forward sun gear and the planet carrier are driv-
en clockwise at the same speed therefore there is
no relative motion between the sun gear and the
pinions.

•

The ring gear and output shaft are driven in a clock-
wise or forward direction at input shaft speed.

•

The C4 clutch is applied to bypass the 3-4 OWC
and provide engine braking on overrun.

Control

To maintain this arrangement in the steady state sole-
noids and valves are activated as follows:

•

Solenoid S1 is switched OFF. S2 is switched OFF.

•

With S1 and S2 switched OFF, the 2-3 and 3-4 shift
valves are held in the third gear position by line
500 pressure.

•

The 1-2 shift valve is held in the third gear position
by S1-S2 oil pressure.

•

2nd oil (line pressure) from the 1-2 shift valve is di-
rected to the band apply feed regulator valve and
to the 2-3 shift valve.

•

The band apply feed regulator valve supplies 2nd
oil (regulated to line pressure multiplied by the valve
ra-tio) to the Band Apply Feed (BAF) circuit.

•

Band apply feed oil is directed to;

- The outer apply area of the front servo

- The 1-2 shift valve to provide an exhaust port

when the transmission is shifted to first gear

- The 3-4 shift valve for use when the transmission

is shifted into fourth gear

•

2nd oil at the 2-3 shift valve is directed to the 3rd
oil circuit.

•

3rd oil from the 2-3 shift valve is directed to the
clutch apply regulator valve, and to the 4-3
sequence valve.

•

The clutch apply regulator valve supplies oil (regu-
lated to line 500 pressure multiplied by the valve
ratio) to the Clutch Apply Feed (CAF) circuit.

The CAF oil is directed to;

- The C1clutch

- The 4-3 sequence valve

•

At the 4-3 sequence valve the CAF oil becomes
Band 1 Release Feed (B1R-F) oil, and is directed
through the 3-4 shift valve to the spring end of the
4-3 sequence valve, and to the release side of the
front servo piston to hold band 1 OFF.

•

Drive (line pressure) is routed through the 3-4 shift
valve to apply the C4 clutch.
