Power Flow - Reverse
In Reverse, transmission drive is via the input shaft
and the forward clutch cylinder to the hub of the C3
clutch. The elements of the transmission function as
follows;
The C3 clutch is engaged and drives the reverse
sun gear in a clock-wise direction.
The B2 band is engaged and holds the planetary
gear carrier stationary causing the long pinion to
rotate anti-clockwise about its axis on the pinion
shaft.
The long pinion drives the internal ring gear in the
same direction.
The internal ring being splined to the output shaft
drives it in an anti-clockwise or reverse direction.Control
To maintain this arrangement in the steady state sole-
noids and valves are activated as follows;
Solenoids S1 and S2 are switched OFF.
Line pressure is directed through the reverse lockout
valve to both the inner and outer apply areas of the
rear servo piston for B2 band application.
Line pressure feeds the reverse oil circuit via the
manual valve.
Reverse oil is routed from the manual valve to the
C3 clutch.
Reverse oil is also applied to the spring end of the
primary regulator valve to assist the spring and to
boost the line pressure value.
All other clutch and band apply circuits are open to
exhaust.

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.

Power Flow - Drive 4 (Overdrive)
In Drive 4 (Overdrive), transmission drive is via the
input shaft to the forward clutch cylinder.
The elements of the transmission function as follows;
The C1 clutch is applied to drive the planet carrier
clockwise.
The B1 band is applied to hold the reverse sun gear
stationary.
As the planet carrier tuns, the long pinion walks
around the stationary reverse sun gear and rotates
around its axis driving the internal ring gear and
output shaft in a clockwise or forward direction at a
speed faster than the input shaft i.e. in overdrive
ratio.
The forward sun gear is also driven faster than the
input shaft and overruns the 3-4 OWC.
The C2 clutch is engaged to reduce the speed differ-
ential across the 3-4 OWC.
Control
To maintain this arrangement in the steady state sole-
noids and valves are activated as follows;
Solenoid S1 is switched ON. S2 is switched OFF.
With S1 switched ON, the 3-4 shift valve is held in
the fourth gear position by line 500 pressure on the
small end of the valve.
With S2 switched OFF, the 2-3 shift valve is held in
the fourth gear position by line 500 pressure on the
large end of the valve.
The 1-2 shift valve is held in the fourth gear position
by 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.
