1. FUNCTION OF COMPONENTS
FUNCTIONOPERATION
O/D Direct Clutch (C0)Connects overdrive sun gear and overdrive carrier
O/D Brake (B0)Prevents overdrive sun gear from turning either clockwise or
counterclockwise
O/D One±way Clutch (F0)When transmission is being driven by engine, connects overdrive sun
gear and overdrive carrier.
Front Clutch (C1)Connects input shaft and intermediate shaft
Rear Clutch (C2)Connects input shaft and front and rear planetary sun gears
No.1 Brake (B1)Prevents front and rear planetary sun gears from turning either clockwise
or counterclockwise
No.2 Brake (B2)Prevents outer race of F1 from turning either clockwise or counterclockwise, thus
previnting front and rear planetary sun gears from turning counterclockwise
No.3 Brake (B3)Prevents front planetary carrier from turning either clockwise or counterclockwise
No.1 One±way Clutch (F1)When B2 is operating prevents front and rear planetary sun gears from turning
counterclockwise
No.2 One±way Clutch (F2)Prevents front planetary carrier from turning counterclockwise

Power from the engine transmitted to the input shaft via the torque converter is then transmitted to the
planetary gears by the operation of the clutch.
By operation of the brake and one±way clutch, either the planetary carrier or the planetary sun gear
are immobilized, altering the speed of revolution of the planetary gear unit.
Shift change is carried out by altering the combination of clutch and brake operation.
Each clutch and brake operates by hydraulic pressure; gear position is decided according to the throttle
opening angle and vehicle speed, and shift change automatically occurs.
The conditions of operation for each gear position are shown on the following illustrations:

2. HYDRAULIC CONTROL SYSTEM
The hydraulic control system is composed of the oil pump, the valve body, the solenoid valves, the accu-
mulators, the clutches and brakes, and the governor valve as well as the fluid passages which connect
all of these components.
Based on the hydraulic pressure created by the oil pump, the hydraulic control system governs the hy-
draulic pressure acting on the torque converter clutch, clutches and brakes in accordance with the ve-
hicle driving conditions.
There are three solenoid valves on the valve body.
The No.1 and No.2 solenoid valves are turned on and off by signals from the ECM to operate the shift
valves and change the gear shift position.
The No.3 solenoid valve is operated by signals from the ECM to engage or disengage the lock±up
clutch of the torque converter.

2. ELECTRONIC CONTROL SYSTEM
The electronic control system for controlling the shift timing and the operation of the lock±up clutch is
composed of the following 3 parts:
(a) Sensors: These sense the vehicle speed and throttle position and send this data to the ECM in the form
of electronic signals.
(b) ECM: This determines the shift and lock±up timing based upon the signals from the sensors.
(c) Actuators: Solenoid valves divert hydraulic pressure from one circuit of the hydraulic control unit to
another, thus controlling shifting and lock±up timing.
