Gear Noise

Gear noise or whine is audible from 32 to 89 km/h (20 to 55 mph) under four driving conditions:
- Drive - Acceleration or heavy pull
- Road Load - Vehicle driving load or constant speed
- Float - Using enough throttle to keep the vehicle from driving the engine, the vehicle slows down gradually but the engine still pulls slightly.
- Coast - Throttle is closed and the vehicle is in gear. Gear noise most frequently has periods where the noise is more noticeable, usually 48 to 64 km/h (30 to 40 mph) and 80 to 89 km/h (50 to 55 mph).
