Operation. When the lock-up clutch is actuated, it rotates together with the pump impeller and turbine runner. Engaging and disengaging of the lockup clutch is determined by changes in the direction of the hydraulic fluid flow in the torque converter when the vehicle reaches a certain speed.1. Disengaging.When the vehicle is running at low speeds, the pressurized fluid (converter pressure) flows to the front of the lock-up clutch. Therefore, the pressure on the front and rear sides of the lock-up clutch become equal, so the lock-up clutch disengages.2. Engaging. When the vehicle is running constantly at medium or high speed (generally above 60 km/h), the pressurized fluid flows to the rear of the lock-up clutch.herefore, the pressure on the front and rear sides of the lock-up clutch become equal, so the lock-up clutch disengages. 2.
