Shift solenoid valve E is turned OFF by the PCM, and shift solenoid valve E pressure (SE) is not applied to the lock-up
shift valve. The lock-up shift valve stays to the right to 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 prescribed value, shift solenoid valve E is turned ON by the PCM, 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 (91) port, which goes to the right side of the torque converter, and
the port of torque converter pressure (94) 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 the A/T clutch pressure control solenoid valve A, and A/T clutch pressure control solenoid valve A pressure
(55) is applied to the lock-up shift valve and 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 the torque converter clutch lock-up until fluid between the
clutch piston and 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 side by
the increased pressure. Then 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.

The shift lever has five positions; the P, R, N, D, and D3 positions. The D position has two modes; automatic shift mode
and sequential sportshift mode with the shift lever moved to the M position. The shift lever shifts along with the A/T
gear position indicator panel. The shift lever can be shifted out of the P position and into the R position without
pressing the shift lever. The shift lock/reverse lock mechanism is an additional shift lever lockout mechanism.
The shift lever is engaged with the shift lever link in the P, R, N, D, and D3 positions. This unit shifts the transmission
using the shift cable connected between the shift cable link and the transmission control shaft.
In the M position, the shift lever is disengaged from the shift lever link, and the shift lever can be used to shift gears
manually between 1st through 5th, much like a manual transmission.
