* Excessive RPMs: Second gear is designed for low speeds and high torque. At 60 mph, the engine will be revving far beyond its safe operating range, causing significant strain on many components.
* Engine damage: High RPMs generate excessive heat, which can lead to overheating, burned valves, piston damage, and ultimately, catastrophic engine failure.
* Transmission damage: The transmission will also be under immense stress, potentially leading to gear stripping, bearing failure, and other costly repairs.
* Clutch damage (manual transmission): If you have a manual transmission, holding the clutch in to maintain that speed would also cause significant damage to the clutch.
In short, driving at a speed significantly above the intended gear range is a recipe for major mechanical problems and expensive repairs.
