Torque converters have a mechnical lock-up. At a certain point (or speed), the torque converter will mechanically lock up. This means that the engine and the tranny are mechanically locked (no slipping, sliding clutches there). It releases when speeds or RPM's go down however, reverting back to "automatic" mode.
