Quizplus · Accepted Answer

The TCC (Torque Converter Clutch) assembly does allow for a mechanical link between the impeller and the turbine, providing a direct drive that improves fuel efficiency and performance, which is what Technician A describes. Technician B is also correct in stating that this mechanical link is not engaged in Park, Reverse, Neutral, and Drive Range-First Gear, as the TCC typically engages in higher gears to provide the benefits of a direct drive while maintaining the flexibility of an automatic transmission.
