On the other hand, automatic gearboxes optimize gear shifting without driver intervention, making them more user-friendly, especially in stop-and-go traffic scenarios. In automatic transmissions, a hydraulic system controls the gear shifts, allowing for smooth transitions between different gears based on the vehicle's speed and engine load. The advent of Continuously Variable Transmissions (CVT) and Dual-Clutch Transmissions (DCT) has further enhanced the functionality of automatic gearboxes. CVTs offer an infinite range of gear ratios, thereby improving fuel efficiency and providing a seamless driving experience. Meanwhile, DCTs deliver quick and precise gear changes, improving acceleration and overall performance.
