1. Manual-automatic transmission is an automatic transmission with additional functions, allowing the driver to manually send gear-shifting signals to the transmission computer, simulating the feel of shifting gears in a manual transmission vehicle. 2. It features two sets of gearboxes with different gear ratios, enabling the selection of different shifting modes based on driving conditions. For example, automatic mode can be used in heavy traffic to reduce operational intensity, while manual mode can be chosen for long-distance or high-speed driving to experience the thrill of acceleration and overtaking, enhancing driving pleasure. 3. In principle, there is little difference, but in terms of acceleration and overtaking, manual-automatic transmission allows the driver to shift gears more freely, reducing the shift time compared to a single automatic transmission. Manual mode offers greater flexibility, such as when downshifting is needed for overtaking, where manual control can be utilized.

As a full-time mom, I've driven both automatic and semi-automatic cars to take my kids to school. Automatic transmissions are incredibly hassle-free—just shift into D and the car changes gears on its own. In traffic jams, there's no need to worry about shifting, giving both hands and feet a break—it's as comfortable as autonomous driving. Semi-automatic adds a manual mode, allowing gear shifts via the steering wheel or gear lever, like using lower gears to control speed downhill or for more aggressive acceleration. But in the city, it's rarely useful, making pure automatic a better fit for the chaos of daily life. After all, raising kids is exhausting enough—less hassle is better. On weekend trips, trying manual mode in a semi-automatic can be a bit fun, but it's less practical than automatic, so I recommend pure automatic for busy families.
