AUTOMATIC TRANSMISSION (3 A / T) (VEHICLE WITH WU-TWC) 7B-3
GENERAL DESCRIPTION
The automatic transmission consists of the hydraulic torque converter, electronically controlled 3-speed automatic
transmission, countershaft and differential.
The transmission consists of 2 planetary gears, 2 disk clutches, 1 band brake, 1 disk brake and 1 one-way clutch.
Its operation is controlled by selecting a position from 6 positions (P, R, N, D, 2 and L ranges) manually by means
of the selector lever installed on the compartment floor.
In the D or 2 range, the gear ratio is changed for the 1st, 2nd or 3rd speed (D range only) automatically by engine
control module (electronic control).
For the automatic transmission fluid, DEXRON

or its equivalent must be used. Lubrication
in the automatic transmission is provided by the oil pump which is operated by the engine revolution. Therefore,
the engine should not be stopped even during coasting to obtain proper lubrication.
When it becomes necessary to be towed, front wheels must be raised so as not to roll them.

TRANSMISSION RANGE SENSOR (SHIFT SWITCH)
Being linked with the selector lever, this sensor changes selector
lever positions into electric signals and send them to the engine
control module. The contact points of this sensor for P and N ranges
are also connected with the starting motor circuit.
So when the selector lever is shifted to the P or N range position,
the contact points for P or N range are connected and cause the
starting motor to operate by turning the starter switch ON.
When the selector lever is in any other position than P and N
ranges, the sensor remains OFF and therefore the starting motor
cannot be operated, that is, the engine cannot be started.
Also, as its contact point for R range is connected with the backup
lamp circuit, only when the selector lever is shifted to R range, the
contact point contacts to light the backup lamp.
DIRECT CLUTCH AND 2ND BRAKE SOLENOID
VALVES
These solenoid valves are mounted on the valve body. They are
turned ON and OFF by the signals from the engine control module
and actuate each shift valve (1 – 2 and 2 – 3 valves) so as to control
transmission gear shift.
Shift solenoid-B (2nd brake solenoid valve) operates 1 – 2 shift
valve, and shift solenoid-A (direct clutch solenoid valve) does 2 –
3 shift valve.

Ignition signal

With the diagnosis switch terminal of monitor coupler for ECM not
grounded, the ignition switch turned ON (but the engine at stop) and
regardless of the condition of the engine and emission control sys-
tem, ECM indicates whether a trouble has occurred in the immobi-
lizer control system or not by causing the malfunction indicator lamp
to flash or turn ON.
Malfunction indicator lamp is ON:
No trouble exists in the immobilizer control system.
Malfunction indicator lamp is flashing:
ECM or Immobilizer Control Module has detected some trouble in
the immobilizer control system.
NOTE:
As soon as the ignition switch is turned ON, ECM and Immobi-
lizer Control Module diagnose if a trouble has occurred in the
immobilizer control system. While the diagnosis is being
made, the malfunction indicator lamp stays ON and if the diag-
nosis result is “abnormal”, it immediately changes to flashing
but if the result is “normal”, it remains ON. Diagnosis takes
about 3 seconds at maximum.
