When shifting to R, the PCM turns shift solenoid valves B and E ON, and A, C, and D are turned OFF. Shift solenoid
valve B pressure (SB) is applied to the right side of shift valve B, and shift valve B is moved to the left side. Shift
solenoid valve E pressure (SE) is applied to the left side of shift valve E, and shift valve E is moved to the right side.
Line pressure (1) changes to (3) at the manual valve, and flows to the servo valve via shift valve E. The servo valve is
moved to the reverse range position. Movement of shift valves B and E, and the servo valve creates 4th clutch
pressure line between the 4th clutch and A/T clutch pressure control solenoid valve A. 4th clutch pressure (40) is
appliedtothe4thclutch,andthe4thclutchisengagedgently.
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.

The lock-up mechanism of the torque converter clutch operates in D and S (2nd, 3rd, 4th, and 5th gears). The
pressurized fluid is drained from the back of the torque converter through a fluid passage, causing the torque
converter clutch piston to be held against the torque converter cover. As this takes place, the mainshaft rotates at the
same speed as the engine. Together with the hydraulic control, the PCM optimizes the timing and volume of the lock-
up mechanism. When shift solenoid valve E is turned on by the PCM, shift solenoid valve E pressure switches the lock-
up shift valve on. A/T clutch pressure control solenoid valve A and the lock-up control valve control the degree of lock-
up.
Fluid in the chamber between the torque converter cover and the torque converter clutch piston is drained off, and
fluid entering from the chamber between the pump and the stator exerts pressure through the torque converter clutch
piston against the torque converter cover. The torque converter clutch piston engages with the torque converter cover;
the torque converter clutch lock-up is ON, and the mainshaft rotates at the same speed as the engine.
Fluid entered from the chamber between the torque converter cover and the torque converter clutch piston passes
through the torque converter and goes out through the chambers between the turbine and the stator, and between the
pump and the stator. As a result, the torque converter clutch piston moves away from the torque converter cover, and
the torque converter lock-up clutch is released; the torque converter clutch lock-up is OFF.

The PCM turns shift solenoid valve E OFF, and shift solenoid valve E pressure (SE) is not applied to the lock-up shift
valve. The lock-up shift valve remains to the right uncover the torque converter pressure ports leading to the left side
of the torque converter and releasing pressure from the right side of the torque converter. Torque converter pressure
(92) changes to (94) at the lock-up shift valve, and enters into the left side of the torque converter to disengage the
torque converter clutch. This keeps the torque converter clutch piston keeps away from the torque converter cover and
the torque converter clutch lock-up is OFF.
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 E ON, and shift
solenoid valve E pressure (SE) is applied to the right side of the lock-up shift valve. The lock-up shift valve is moved to
the left side to switch the torque converter pressure port (91), which goes to the right side of the torque converter, and
torque converter pressure port (94) is released from the left side of the torque converter. Torque converter pressure
(91) flows to the right side of the torque converter to engage the torque converter clutch. The PCM also controls A/T
clutch pressure control solenoid valve A to regulate A/T clutch pressure control solenoid valve A pressure. A/T clutch
pressure solenoid valve A (55) is applied to the lock-up shift valve and the lock-up control valve. The position of the
lock-up control valve depends on A/T clutch pressure control solenoid valve A pressure (55) and torque converter
pressure released from the torque converter. The lock-up control valve controls the amount of torque converter clutch
lock-up until fluid between the clutch piston and the torque converter cover is fully released; the torque converter
clutch is in partial lock-up.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.

When the vehicle speed increases, the PCM sends a signal to A/T clutch pressure control solenoid valve A to increase
A/T clutch pressure control solenoid valve A pressure (55), and the lock-up control valve is moved to the left by the
increased pressure. Then torque converter pressure (94) from the left side of the torque converter is completely
released at the lock-up control valve, and torque converter pressure (91) engages the torque converter clutch securely;
the torque converter clutch is in full lock-up.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the hydraulic circuit.
