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.

AUTOMATIC TRANSMISSION 5A-29
•
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.
