An automobile transmission is a mechanical system that transfers power from the engine to the wheels, allowing the vehicle to move. It adjusts the engine's output to match the speed and power needed for different driving conditions. There are two main types of transmissions: manual and automatic. In a manual transmission, the driver changes gears using a clutch and gear stick, while in an automatic transmission, the system shifts gears automatically based on speed and load. Both types play a crucial role in optimizing performance and fuel efficiency, ensuring a smooth driving experience.
