What should be done if the torque converter temperature exceeds 350 degrees?

Answer: C — Shut down the engine

Shutting down the engine is the appropriate response when the torque converter temperature exceeds 350 degrees. This high temperature indicates a potential malfunction or severe overload within the torque converter, which can lead to damage if not addressed promptly. By shutting down the engine, you prevent further heat buildup and possible catastrophic failure of the component, which could result in costly repairs and safety hazards. In scenarios where temperatures rise excessively, continuing to operate the equipment, either by increasing speed or reducing load, may exacerbate the situation, leading to further overheating and damage. Contacting maintenance is a prudent step afterward, but it is critical to first halt the engine to ensure immediate safety and prevent further harm to the vehicle's systems.
