What are the reasons for a sudden inability to shift gears in a HOWO truck?

[BrooklynLynn]

The reasons for a sudden inability to shift gears in a HOWO truck are as follows: 1. No fuel: The fuel gauge shows below the red line, naturally making it impossible to start. 2. Dead battery: This could be due to a drained battery from leaving headlights on for too long or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. Checking for a dead battery is simple—just press the horn. 3. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) to start. If it's in R (Reverse) or D (Drive), the vehicle won't start. Some manual transmission vehicles also won't start if the clutch isn't pressed. 4. Lack of antifreeze: Some owners use water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions, leading to a cracked engine and a non-functional water pump. This prevents the vehicle from starting and can damage other engine components.
