An automotive transmission is a system in vehicles that transfers power from the engine to the wheels. It allows the vehicle to change speeds and manage torque, enabling smooth acceleration and deceleration. Transmissions can be manual, where the driver shifts gears, or automatic, which shifts gears on its own based on speed and load. There are several types of transmissions, including automatic, manual, and continuously variable transmission (CVT). Each type has its own advantages and disadvantages, affecting fuel efficiency, performance, and driving experience. Proper maintenance of the transmission is essential for the longevity and reliability of the vehicle.
