Lock-Up Control
Shift solenoid valve C and A/T clutch pressure control solenoid valve D control the hydraulic pressure to switch the lock-up shift valve and lock-up ON and OFF. When the PCM actuates shift solenoid valve C and A/T clutch pressure control solenoid valve D ON, lock-up starts. A/T clutch pressure control solenoid valve D applies and regulates hydraulic pressure to the lock-up control valve to control the amount of lock-up.
The lock-up mechanism operates:
- D - accelerating in 1st, 2nd, 3rd, 4th, 5th, and 6th gears
- D - decelerating in 2nd, 3rd, 4th, 5th, and 6th gears
- L - accelerating in 1st and 2nd gears
- L - decelerating in 2nd gear
