What are the 4 gears of an automatic transmission car?
3 Answers
Pure automatic transmissions generally have P, R, N, D, D3/D2/D1. The following is a related introduction: 1. Introduction to automatic transmission cars: Generally, cars that use automatic transmissions (AT) to adjust speed. When 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 gear shifting operations. 2. Operating characteristics of automatic transmission cars: When driving a modern automatic transmission car, the driver only needs to control the accelerator pedal. The computer analyzes signals such as engine throttle opening and vehicle speed collected by sensors, automatically controlling the transmission or shifting the transmission into different gears. Generally, automatic transmissions result in some loss of engine power.
I've been driving automatic transmission cars for over a decade and use these gears every day. Let's start with P (Park) - you engage it when parking to lock the wheels and prevent rolling, absolutely essential when parking in lots or at home. R (Reverse) is for backing up, used when reversing out of parking spaces or garages; always proceed slowly and check mirrors carefully. N (Neutral) is for temporary stops like long red lights or car washes, though I rarely use it since coasting can be risky - better to combine with the handbrake. D (Drive) is the main gear for normal driving, suitable for both city and rural roads. The gear design is quite user-friendly, and beginners will naturally get accustomed with practice. Remember: never shift gears recklessly while moving, especially avoiding direct shifts from D to R or P, as this can damage the transmission - costly and labor-intensive to repair. Safety comes first when driving; it gets easier with familiarity.
I just learned to drive this year, and my coach taught me in detail about the four gears of an automatic transmission. P stands for Park, which is the parking gear. You must engage it after parking to prevent the car from moving. R is Reverse, used when backing up. I practiced it several times at the driving range before getting the hang of it. N is Neutral. The coach said it can be used for brief stops, like at long red lights, but it’s not very safe as the car can roll, so it’s best to use it sparingly. D is Drive, the gear you use when driving. It’s especially simple and hassle-free, unlike manual transmissions where you have to shift gears. After actually hitting the road, I realized that observation and practice are the most important. Shifting into the wrong gear can be dangerous—for example, never forget to shift back to D after reversing. It’s normal to feel nervous as a beginner, but practicing a few times every day will help you get used to it quickly. Remember, using the gears correctly makes driving much easier.
