Homonym: Transmissions (Broadcasting)
Transmissions are devices in vehicles that transfer power from the engine to the wheels, allowing the car to move. They help control the speed and torque of the vehicle, making it easier to drive under different conditions. There are two main types of transmissions: manual and automatic.
In a manual transmission, the driver uses a clutch pedal and gear stick to change gears, while in an automatic transmission, the system changes gears automatically based on speed and engine load. Both types play a crucial role in the overall performance and efficiency of vehicles, including cars and trucks.
