A car's gearbox (transmission) transfers power from the engine to the wheels while adjusting speed and torque (turning forc• Torque Multiplier for Starting and Climbing: Lower gears use larger gears inside the box to deliver high torque with low speed, helping the car pull away from a stop, go up steep hills, or carry heavy loads.
• Speed Booster for Cruising: Higher gears use smaller gears to deliver high wheel speed with lower engine effort, allowing the car to travel efficiently at highway speeds.
• Reversing Direction: A reverse gear reverses the rotation of the output shaft so the car can move backward.
• Neutral Idle: A neutral position disconnects power transfer so the engine can run while the car remains completely stationary without pressing the brakes.
• Engine Protection and Efficiency: It keeps the engine operating
