How do gears work in a standard transmission?
Basically, a manual transmission is a gear box that enables the driver to choose between different gear ratios to drive the car. Lower gear ratios offer more torque, but less speed, while higher gear ratios offer less torque, but higher speed. The gears themselves are not fixed to the output shaft, but freewheel.
How does an automatic transmission work?
The most common type of automatic transmission uses hydraulic power to shift gears. The torque converter connects the engine to the transmission and uses pressurized fluid to transfer power to the gears. This apparatus replaces a manual friction clutch and lets the vehicle come to a complete stop without stalling.
Why do you need to change gears when driving?
The basic rule is that you change up through the gears as the speed of the car increases and down when you need more power from the engine. For example, you would change down to a lower gear when climbing a hill or pulling away at low speed. The gears determine the amount of power available from the engine.
