Lock-up Control
Shift solenoid valve E controls the hydraulic pressure to switch the lock-up shift valve and lock-up ON and
OFF. The PCM actuates shift solenoid valve E and A/T clutch pressure control solenoid valve A to control the
torque converter clutch lock-up. When shift solenoid valve E is turned ON, the lock-up condition starts. A/T
clutch pressure control solenoid valve A regulates and apply the hydraulic pressure to the lock-up control valve
to control the amount of the lock-up. The lock-up mechanism operates in 2nd, 3rd, 4th, and 5th gears in the D
position, and 2nd and 3rd gears in the D position D3 driving mode.
