Deceleration Lock-up

• Lock-up Control Solenoid Valve A: ON
• Lock-up Control Solenoid Valve B: Duty Operation OFF ↔ ON
• Linear Solenoid Pressure: Low

The PCM switches solenoid valve B on and off rapidly under certain conditions. The slight lock-up and half lock-up regions are maintained so as to lock the torque converter properly.
