What is the difference between automatic transmission and manual-automatic transmission?
2 Answers
The differences between automatic transmission and manual-automatic transmission are as follows: 1. Different methods: (1) Manual-automatic transmission: A transmission method that combines manual shifting and automatic shifting in cars, allowing manual control of gear selection and engine speed. (2) Automatic transmission cars: Cars that use an automatic transmission (AT) to adjust speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine speed and load, replacing the driver's subjective judgment of timing and shifting operations. 2. Different characteristics: (1) Manual-automatic transmission: Manual-automatic transmissions require higher maintenance costs and strict usage requirements. (2) Automatic transmission cars: When the gear lever is placed in the drive position and the brake pedal is released, as the throttle is applied and the engine speed increases, the transmitted torque increases, pushing the car forward. 3. Different experiences: (1) Manual-automatic transmission: Driving feels smooth and sporty, offering a great deal of driving pleasure. (2) Automatic transmission cars: Convenient and hassle-free, especially in traffic jams or when facing uphill slopes, the advantages of automatic transmission become more apparent.
I've been driving automatic transmission cars for almost ten years and have deeply felt the differences between them. Automatic transmission is foolproof operation—just shift to D and step on the gas or brake, and the gearbox will shift gears on its own, which is especially worry-free in traffic jams. The manual-shift mode on automatic transmissions adds manual shifting functionality on top of the automatic, with plus/minus buttons or paddles next to the gear lever to simulate the manual transmission experience. For daily commuting, automatic mode is sufficient, but when driving on mountain roads or overtaking on highways, switching to manual mode is better, as downshifting provides more direct acceleration. When I drove my friend's car with manual-shift mode down a long slope, I often used lower gears, and the engine braking effect was noticeable. It's important to note that the manual mode in these transmissions isn't purely mechanical—it's essentially an electronic signal commanding the gearbox to shift.
