How does a Range Change Gearbox work?

A Range Change Gearbox, often found in vehicles, allows the driver to select different gear ratiOS to optimize performance for various driving conditions. It typically features multiple gear sets, enabling the selection of low or high ranges. The driver shifts between these ranges using a lever, which engages different gears to either increase torque for climbing or decrease engine load for speed. This system enhances versatility, allowing the vehicle to adapt to terrains like steep hills or open highways.
