What is the difference between automatic transmission and manual transmission?
2 Answers
Automatic transmission and manual transmission differ in the following aspects: 1. Operation: Automatic transmission does not require clutch operation, having only brake and accelerator pedals; manual transmission requires clutch operation for manual gear shifting and reversing. 2. Working principle: Automatic transmission uses planetary gear mechanisms for gear changes, automatically adjusting based on accelerator pedal position and vehicle speed; manual transmission changes gear positions and transmission ratios by moving the gear lever to alter gear engagement within the transmission. 3. Gear indicators: Automatic transmission gear indicators are marked as P, R, N, D; manual transmission gear indicators are marked as 1, 2, 3, 4, 5, 6, R, etc.
Automatic and manual transmissions feel quite different to drive. I usually drive a manual, and in traffic jams, constantly pressing the clutch with my left foot can be a bit tiring, but the sense of control during gear shifts is fantastic—accelerating and decelerating entirely by manually operating the clutch and gear lever makes it feel like the car is completely under my command. Automatic transmissions are different; just shift into D, and the system handles gear changes automatically. In traffic, you only need to control the throttle and brake with your right foot, making it much easier. While automatics are convenient, throttle control isn't as precise, especially when overtaking uphill—it often feels a bit sluggish. Manuals allow techniques like downshifting and rev-matching, which can save some fuel costs, whereas automatics are simpler but usually consume a bit more fuel.
