ELECTRONICALLY CONTROLLED TRANSMISSION
THIS SYSTEM ELECTRONICALLY CONTROLS THE GEAR SHIFT TIMING, LOCK-UP TIMING, THE CLUTCH AND BRAKE HYDRAULIC
PRESSURE, AND THE ENGINE TORQUE DURING SHIFTING TO ACHIEVE OPTIMUM SHIFT FEELING.
IN ACCORDING TO THE VEHICLE DRIVING CONDITIONS AND ENGINE OPERATING CONDITIONS AS DETECTED BY VARIOUS
SENSORS.
1. GEAR SHIFT OPERATION
DURING DRIVING, THE ENGINE CONTROL MODULE SELECTS THE SHIFT FOR EACH GEAR WHICH IS MOST APPROPRIATE TO THE
DRIVING CONDITIONS, BASED ON INPUT SIGNALS FROM THE ENGINE COOLANT TEMP. SENSOR TO TERMINAL THW OF THE
ENGINE CONTROL MODULE, AND ALSO THE INPUT SIGNALS TO TERMINAL SPD OF THE ENGINE CONTROL MODULE FROM THE
SPEEDOMETER DEVOTED TO THE ELECTRONICALLY CONTROLLED TRANSMISSION. CURRENT IS THEN OUTPUT TO THE
ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID. WHEN SHIFTING TO 1ST SPEED, CURRENT FLOWS FROM TERMINAL
S1 OF THE ENGINE CONTROL MODULE "TERMINAL
(A) 3 (2WD) OR (B) 3 (4WD) OF THE ELECTRONICALLY CONTROLLED
TRANSMISSION SOLENOID "GROUND, AND CONTINUES TO THE NO. 1 SOLENOID CAUSES THE SHIFT.
FOR 2ND SPEED, CURRENT FLOWS FROM TERMINAL S1 OF THE ENGINE CONTROL MODULE "TERMINAL 3 OF THE
ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID "GROUND, AND FROM TERMINAL S2 OF THE ENGINE CONTROL
MODULE "TERMINAL
(A) 1 (2WD) OR (B) 6 (4WD) OF THE ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID "
GROUND, AND CONTINUES TO SOLENOIDS NO. 1 AND NO. 2 CAUSES THE SHIFT.
FOR 3RD SPEED, THERE IS NO CONTINUOUS TO NO. 1 SOLENOID, ONLY TO NO. 2 CAUSING THE SHIFT.
SHIFTING INTO 4TH SPEED (OVERDRIVE) TAKES PLACE WHEN THERE IS NO CONTINUOUS TO EITHER NO. 1 OR NO. 2 SOLENOID.
2. LOCK-UP OPERATION
WHEN THE ENGINE CONTROL MODULE JUDGES FROM EACH SIGNAL THAT LOCK-UP OPERATION CONDITIONS HAVE BEEN MET,
CURRENT FLOWS FROM TERMINAL SL OF THE ENGINE CONTROL MODULE "TERMINAL
(A) 2 (2WD) OR (B) 5 (4WD) OF THE
ELECTRONICALLY CONTROLLED TRANSMISSION SOLENOID "GROUND, CONTINUES TO THE LOCK-UP SOLENOID AND CAUSING
LOCK-UP OPERATION.
3. STOP LIGHT SW CIRCUIT
IF THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) WHEN DRIVING IN LOCK-UP CONDITION, A SIGNAL IS INPUT TO
TERMINAL B/K OF THE ENGINE CONTROL MODULE, THE ENGINE CONTROL MODULE OPERATES AND CURRENT TO THE LOCK-UP
SOLENOID IS CUT.
4. OVERDRIVE CIRCUIT
*O/D MAIN SW ON
WHEN THE O/D MAIN SW IS TURNED ON (SW POINT IS OPEN), A SIGNAL IS INPUT TO TERMINAL OD2 OF THE ENGINE CONTROL
MODULE AND ENGINE CONTROL MODULE OPERATION CAUSES GEAR SHIFT WHEN THE CONDITIONS FOR OVERDRIVE ARE MET.
*O/D MAIN SW OFF
WHEN THE O/D MAIN SW IS TURNED OFF (SW POINT IS CLOSED), THE CURRENT FLOWING THROUGH THE O/D OFF INDICATOR
LIGHT FLOWS THROUGH THE O/D MAIN SW TO GROUND. CAUSING THE INDICATOR LIGHT TO LIGHT UP. AT THE SAME TIME, A
SIGNAL IS INPUT TO TERMINAL OD2 OF THE ENGINE CONTROL MODULE AND ENGINE CONTROL MODULE OPERATION
PREVENTS SHIFT INTO OVERDRIVE.

5. CENTER DIFFERENTIAL CLUTCH CONTROL (4WD)
THE CENTER DIFFERENTIAL CLUTCH CONTROL USES A LINEAR SOLENOID TYPE VALVE (SOLENOID VALVE SLD) TO CONTROL THE
CENTER DIFFERENTIAL CLUTCH. BY CONTROLLING THE FLUID PRESSURE, THE LIMITED SLIP DIFFERENTIAL EFFECT OF THE
CENTER DIFFERENTIAL CAN ALWAYS BE MAINTAINED AT THE OPTIMUM FOR THE CURRENT DRIVING CONDITIONS TO INCREASE
ROAD-HOLDING ABILITY.
SOLENOID VALVE SLD OPENS AND CLOSES IN RESPONSE TO SIGNALS FROM THE ENGINE CONTROL MODULE. THUS THE
SOLENOID MODULATOR VALVE MAINTAINS A CONSTANT FLUID PRESSURE FOR OPERATION OF THE CENTER DIFFERENTIAL
CLUTCH CONTROL VALVE AND CENTER DIFFERENTIAL CLUTCH.
*NORMAL DRIVING
SOLENOID VALVE SLD OPENS AND CLOSES IN RESPONSE TO THE THROTTLE OPENING ANGLE TO CONTROL THE FLUID
PRESSURE OPERATING ON THE CENTER DIFFERENTIAL CLUTCH. WHEN THE VEHICLE TAKES OFF IN FIRST GEAR WITH A
LARGE THROTTLE OPENING ANGLE, THE FLUID PRESSURE IS KEPT HIGH. SO EVEN IF THE VEHICLE TAKES OFF SUDDENLY OR
THE ROAD SURFACE IS SLIPPERY, SMOOTH, RELIABLE ACCELERATION IS POSSIBLE.
*SLIPPING
WHEN A LARGE DIFFERENCE OCCURS BETWEEN THE FRONT WHEEL SPEED AND REAR WHEEL SPEED AT LOW SPEEDS,
SOLENOID VALVE SLD IS FULLY CLOSED TO APPLY HIGH FLUID PRESSURE TO THE CENTER DIFFERENTIAL CLUTCH AND
PROVIDE A LARGE LIMITED SLIP DIFFERENTIAL EFFECT.
*WIDE CORNERING
WHEN DIFFERENCES ARISE BETWEEN THE FRONT WHEEL SPEED AND REAR WHEEL SPEED DUE TO DIFFERENCES IN THE
TURNING RADIUS DURING CORNERING AT LOW SPEEDS, SOLENOID VALVE SLD IS FULLY OPEN TO APPLY A WEAK LIMITED SLIP
DIFFERENTIAL EFFECT AND PERMIT SMOOTH CORNERING.
6. ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW
IF THE ELECTRONICALLY CONTROLLED TRANSMISSION PATTERN SELECT SW IS CHANGED FROM NORMAL TO POWER, THE
CURRENT THROUGH THE POWER INDICATOR FLOWS TO GROUND, CURRENT FLOWS TO TERMINAL P OF THE ENGINE CONTROL
MODULE, THE ENGINE CONTROL MODULE OPERATES, AND SHIFT UP AND SHIFT DOWN OCCURS AT HIGHER VEHICLE SPEEDS
THAN WHEN THE SW IS IN NORMAL POSITION.

1. SHIFT LOCK MECHANISM
WITH THE IGNITION SW ON, WHEN A SIGNAL THAT THE BRAKE PEDAL IS DEPRESSED (STOP LIGHT SW ON) AND A SIGNAL THAT
THE SHIFT LEVER IS PUT IN Pº POSITION (CONTINUITY BETWEEN P1 AND P OF THE SHIFT LOCK CONTROL SW) IS INPUT TO THE
ECU, THE ECU OPERATES AND CURRENT FLOWS FROM TERMINAL 1 OF THE ECU "TERMINAL SLS+ OF THE SHIFT LOCK
SOLENOID "SOLENOID " TERMINAL SLS- "TERMINAL 4 OF THE ECU "GROUND. THIS CAUSES THE SHIFT LOCK SOLENOID
TO TURN ON (PLATE STOPPER DISENGAGES) AND THE SHIFT LEVER CAN SHIFT INTO POSITION OTHER THAN THE Pº.
2. KEY INTERLOCK MECHANISM
WITH THE IGNITION SW ON OR ACC POSITION, WHEN THE SHIFT LEVER IS PUT IN Pº POSITION (NO CONTINUITY BETWEEN P2
AND P OF SHIFT LOCK CONTROL SW), THE CURRENT FLOWING FROM TERMINAL 6 OF THE ECU "THE KEY INTERLOCK SOLENOID
IS CUT OFF. THIS CAUSES THE KEY INTERLOCK SOLENOID TO TURN OFF (LOCK LEVER DISENGAGES FROM LOCK POSITION) AND
THE IGNITION KEY CAN BE TURNED FROM ACC TO LOCK POSITION.
