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.

The PCM turns shift solenoid valve C OFF, D ON, A and E remain OFF, and B remains ON. Shift solenoid valve C
pressure (SC) in the right side of shift valve C is released. Shift valve C moves to the right side to switch the ports. This
movement covers the ports to block A/T clutch pressure control solenoid valve pressure at shift valves C and A, and
uncover the line pressure port leading to the 2nd clutch.
Fluid flows to 2nd clutch by way of:
Line pressure (1) Manual valve Line pressure (4) Shift valve C Line pressure (5E) Shift valve B Line
pressure (5F) Shift valve A 2nd clutch pressure (20) 2nd clutch
The2ndclutchpressure(20)isappliedtothe2ndclutch,andthe2ndclutchisengagedsecurely.

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.

applied to the right side of shift valve A. Shift valve A is moved to the left side to cover the A/T clutch pressure control
solenoid valve A and C pressure ports leading to the 2nd and 3rd clutches.
A/T clutch pressure control solenoid valve B pressure (56) changes to (5G) at shift valve C, and becomes 4th clutch

The PCM turns shift solenoid valve C ON, and A and D remain ON, and B and E remain OFF. 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. The directs A/T clutch
pressure control solenoid valve B pressure to shift valve B where it is blocked. The pressure in the 4th clutch is
released through shift valve C.
A/T clutch pressure control solenoid valve C pressure (57) changes to (5L) at shift valve D and to (5N) at shift valve B.
5th clutch pressure (50) is held high by A/T clutch pressure control solenoid valve C, and the 5th clutch is engaged
securely.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

After starting off in reverse gear, the PCM turns shift solenoid valve A ON, B and E remain ON, and C and D remain
OFF. Shift solenoid valve A pressure (SA) is applied to the right side of shift valve A to cover the A/T clutch pressure
control solenoid valve A pressure port, and to uncover the line pressure port leading to the 4th clutch creating full line
pressure. The 4th clutch is engaged securely with line pressure.
When R is selected while the vehicle is moving forward, the PCM commands shift solenoid valve A to turn OFF, and E
to remain OFF. Shift solenoid valve A pressure (SA) is not applied to shift valve A so that line pressure (3A) is not
applied to the servo valve. Also shift solenoid valve E pressure (SE) is not applied to shift valve E so that line pressure
(3’) is not applied to the servo valve. The servo valve cannot be shifted to the reverse position, and hydraulic pressure
is not applied to the 4th clutch from the servo valve for reverse; as a result, power is not transmitted to the reverse
direction.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
