AUTOMATIC TRANSMISSION 5A-49
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 fear 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 solenoids 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 theline pressure value.
All other clutch and band apply circuits are open to exhaust.

5A-52 AUTOMATIC TRANSMISSION 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 solenoids and valves are activated as follows: Solenoid S1 is switched Off. S2 is switched On. Solonoid S1 is switched Off. S2 is switched On.
Drive (line pressure) oil from the manual valve engages 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 directed to the band apply regulator valve, and to the 2-3 shift
valve.
The band apply 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.

5A-54 AUTOMATIC TRANSMISSION POWER FLOW - DRIVE 3 AND MANUAL 3
In Drive 3 and Manual 3, 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.
The C1 clutch is engaged to drive the planet carrier.
The forward sun gear and the planet carrier are driven 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 clockwise 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 solenoids 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 directed to the band apply regulator valve. and to the 2-3 shift
valve.
The band apply 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
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 (regulated to line 500 pressure multiplied by the valve ratio) to the
clutch apply feed (CAF) circuit.
The CAF oil is directed to:
- The C1 clutch- The C1 bias valve- 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 differential across the 3-4 OWC.
Control
To maintain this arrangement in the steady state solenoids 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 directed to the band apply regulator valve, and to the 2-3 shift
valve.
The band apply 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 inner apply area of the front servo piston via the 3-4 shift valve
- the 1-2 shift valve to provide an exhaust port when the transmission is shifted to first 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 (regulated to line 500 pressure multiplied by the valve ratio) to the
clutch apply feed (CAF) circuit.
The CAF oil is directed to:- the C1 clutch- the C1 bias valve- the 4-3 sequence valve
Drive oil (line pressure) from the manual valve engages the C2 clutch
