As the engine turns, the ATF pump starts to operate. Automatic transmission fluid (ATF) is drawn through the ATF
strainer (filter) and discharged into the hydraulic circuit. Then, ATF flowing from the ATF pump becomes line pressure
that is regulated by the regulator valve. Torque converter pressure from the regulator valve enters the torque
converter through the lock-up shift valve, and it is discharged from the torque converter. The torque converter check
valve prevents torque converter pressure from rising.
The PCM switches shift solenoid valves ON and OFF. The shift solenoid valve intercepts line pressure from the ATF
pump via the manual valve when the shift solenoid valve is OFF. When the shift solenoid valve is turned ON by the
PCM, line pressure changes to shift solenoid valve pressure at the shift solenoid valve, then the shift solenoid valve
pressure flows to the shift valve. Applying shift solenoid pressure to the shift valves moves the position of the shift
valve, and switches the port of the hydraulic circuit. The PCM also controls A/T clutch pressure control solenoid valves
A, B, and C. The A/T clutch pressure control solenoid valves regulate hydraulic pressure, and applies pressure to the
clutches to engage smoothly. The clutches receive optimum clutch pressure which is regulated by the A/T clutch
pressure control solenoid valves for comfortable driving and shifting under all conditions.

The PCM controls the shift solenoid valves. The conditions of the shift solenoid valves and positions of the shift valves
are as follows:  Shift solenoid valve A: OFF, and shift valve A remains on the right side
 Shift solenoid valve B: ON, and shift valve B moves to the left side
 Shift solenoid valve C: ON, and shift valve C moves to the left side
 Shift solenoid valve D: OFF, and shift valve D remains on the left side
 Shift solenoid valve E: OFF, and shift valve E remains on the left side
Line pressure (1) flows to the shift solenoid valves and A/T clutch pressure control solenoid valve A. Under this
condition, hydraulic pressure is not applied to the clutches.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

The shift solenoid valves remain the same as in N when shifting to D from N. The manual valve is moved to the D
position, and uncovers line pressure port (4) leading to A/T clutch pressure control solenoid valve C. Hydraulic
pressure to the 1st clutch from A/T clutch pressure control solenoid valve A is created as shift solenoid valve A OFF,
and B and C remain ON. A/T clutch pressure control solenoid valve A pressure (55) changes to 1st clutch pressure (10)
at shift valve B, and flows to the 1st clutch. The 1st clutch is engaged gently when shifting to D from N.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve A OFF, B and C remain
ON, and D and E remain OFF. Shift solenoid valve A pressure (SA) in the right side of shift valve A is released. Shift
valve A is moved to the right side uncovering the A/T clutch pressure control solenoid valve A and B pressure port
leading to the 1st and 2nd clutches. The PCM actuates the A/T clutch pressure control solenoid valve to regulate
hydraulic pressure. A/T clutch pressure control solenoid valve A pressure (55) changes to 1st clutch pressure (10) at
shift valve B. A/T clutch pressure control solenoid valve B pressure (56) changes to (5E) at shift valve C and to (5F) at
shift valve B, and becomes 2nd clutch pressure (20) at shift valve A. The 1st and 2nd clutches are engaged gently.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

FINAL DRIVE
GEAR
As the speed of the vehicle reaches the programmed value, the PCM turns shift solenoid valve C ON, A and E remain
OFF, and B and D remain ON. Shift solenoid valve C pressure (SC) is applied to the right side of shift valve C. Shift
valve C is moved to the left side uncovering the A/T clutch pressure control solenoid valve B and C pressure ports
leading to the 2nd and 3rd clutches. The PCM actuates the A/T clutch pressure control solenoid valves to regulate
hydraulic pressure. A/T clutch pressure control solenoid valve B pressure (56) changes to 2nd clutch pressure (20) at
shift valve A. A/T clutch pressure control solenoid valve C pressure (57) changes to (5H) at shift valve C and to (5K) at
shift valve B, and becomes 3rd clutch pressure (30) at shift valve A. The 2nd and 3rd clutches are engaged gently.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

The PCM turns shift solenoid valves B and D OFF, A and E remain OFF, and C remains ON. Shift solenoid valve B
pressure (SB) in the right side of shift valve B is released, and shift valve B is moved to the right side. Shift solenoid
valve D pressure (SD) in the left side of shift valve D is released, and shift valve D is moved to the left side. This valve
movement causes A/T clutch pressure control solenoid valve C pressure port leading to the 3rd clutch.
A/T clutch pressure control solenoid valve C pressure (57) changes to (5J) to be directed to shift solenoid valve D and
to (5K) at shift valve B, and becomes 3rd clutch pressure (30) at shift valve A. 3rd clutch pressure (30) is applied to the
3rd clutch, and the 3rd clutch is engaged securely.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
