The gear system in a vehicle's transmission adjusts the engine's power to suit different driving conditions by changing the torque and speed delivered to the wheels. Lower gears provide high torque and low speed, useful for starting and climbing, while higher gears offer lower torque and higher speed for cruising. In manual transmissions, the driver uses a clutch and gear stick to manually select gears, whereas automatic transmissions use planetary gear sets and a torque converter to shift gears
