Is there a difference between automatic transmission and manual-automatic transmission?
3 Answers
The difference between the two lies in their mechanical construction. Below is an introduction to the relevant knowledge about manual-automatic transmission vehicles: 1. Definition: "Manual-automatic transmission" combines the manual shifting and automatic shifting of a car into one transmission method. 2. Advantages: The manual-automatic transmission is an added feature to improve the economy and controllability of the automatic transmission, allowing the driver to regain control over the shifting timing that was originally decided by the computer. At the same time, in the case of urban traffic congestion, the automatic transmission can still be used at any time to make driving easier.
The difference between automatic transmission and semi-automatic transmission is quite obvious. Automatic transmission means you don't have to worry about gears at all, just put it in D and drive anywhere. It's perfect for stop-and-go traffic during rush hours, especially friendly for beginners and female drivers. However, semi-automatic transmission is essentially an automatic transmission with a 'manual mode'. Normally it still shifts automatically, but when you switch to M gear or use paddle shifters, you can manually control gear changes. For example, when driving on mountain roads, manually shifting to 2nd gear provides more stable engine braking; when overtaking, manually downshifting to raise RPM delivers much faster acceleration than simply pressing the throttle. Of course structurally, semi-automatic transmissions have an additional manual switching mechanism, which might add some extra steps during repairs.
I've driven cars with both types of transmissions, and the automatic is indeed more convenient. You don't need to coordinate the clutch and throttle when starting at traffic lights, and beginners don't have to worry about rolling back on slopes. But the manual-automatic transmission is more versatile. You can use the automatic mode to relax in traffic jams during weekdays, and switch to manual mode for some driving fun on highways during weekends. Nowadays, many cars have paddle shifters hidden behind the steering wheel—just a flick of your finger can drop two gears, and the roaring engine sound is particularly thrilling. As for drawbacks, manual-automatic transmissions cost a few thousand more, and many people never use the manual function after buying, which is a bit of a waste. If you don't pursue driving sensation, a regular automatic transmission is hassle-free enough.
