What does the C gear mean in trucks?

C gear is the climbing gear, also known as the half gear. Below is the relevant introduction about the C gear in trucks: 1. Concept: The C gear is the climbing gear, also known as the half gear. For example, when driving on muddy roads or climbing slopes, the half gear comes into play. 2. Application: It is mainly used in heavy-duty trucks when carrying heavy loads and under poor road conditions. It can reduce speed and increase torque, meaning the forward traction is enhanced, improving the passability of heavy-duty vehicles in poor road conditions. The gear ratio of the half gear is the largest among all gears, hence it provides the strongest traction. When making a left turn, try to make the turn as wide as possible. This is because some vehicles might be coming out of the road you intend to turn into. To avoid obstruction or collisions and other hazards, you should try to turn into a spot further away.
I've driven many automatic transmission trucks, and the C gear is essentially a speed control mode, especially useful when going downhill. It helps slow down the vehicle using engine braking, reducing wear on the brake pads and preventing overheating or failure—super practical on mountain roads. During long-distance hauls, I switch to C gear in advance, particularly when carrying heavy loads. It makes the ride much steadier, extends brake life, and ensures safety and peace of mind. Remember, don’t wait until the slope gets steep—prepare early and make it a habit to avoid sudden braking risks.
