Question: During a routine inspection of a heavy-duty front-end loader, the technician notes a significant amount of metallic particles in the powershift transmission's magnetic drain plug. The transmission fluid appears dark and has a burnt odour. What is the most immediate concern?

Answer options:

• A failing torque converter ✅ Accelerated wear of clutch packs or planetary gears
• Contaminated transmission fluid cooler
• Incorrect transmission fluid level

Correct answer: Accelerated wear of clutch packs or planetary gears

Explanation: Metallic particles on the magnetic drain plug and burnt fluid strongly indicate accelerated wear of internal components such as clutch packs or planetary gears within the powershift transmission. While other issues could exist, accelerated wear is the direct cause of these symptoms leading to imminent failure. A failing torque converter would likely present with different symptoms such as overheating or lack of power. Contamination of the cooler or incorrect fluid level would not typically produce metallic particles.
