The speeds for gears 1, 2, and 3 are: 1st gear 10-20 km/h, 2nd gear 20-30 km/h, 3rd gear 30-40 km/h. Below is an introduction to the various gears of an automatic transmission car: Gear shifting steps: When starting the car, shifting from P to D passes through R, which causes a reverse impact on the transmission and damages it. Over time, the damage can be significant. The correct method is to turn on the power, press the brake, shift to N, then start the engine and shift to D. P gear: The parking gear uses a mechanical device inside the transmission to lock the rotating parts of the car. It should only be used when the vehicle is completely stopped. Additionally, the gear must be in P when the car is turned off. N gear: This is the neutral gear, typically used for brief stops. In this gear, the right foot can be lifted off the brake pedal to rest. However, on slopes, the brake must still be pressed to prevent the car from rolling unless the handbrake or electronic brake is engaged.

The speeds for 1st, 2nd, and 3rd gears aren't fixed numbers—it all depends on the type of car you're driving. I often drive a manual transmission car: 1st gear is for starting, usually around 0 to 15 km/h, and you should shift when the engine hums lightly; 2nd gear accelerates to about 15 to 30 km/h, ideal for small city curves; 3rd gear can go up to 30 to 50 km/h, making acceleration smoother. But these numbers can vary—for example, my old car has a weak engine, so 2nd gear is its limit. Don't stay at high RPM in 1st gear for too long, as it can wear out parts. The car manual is the best reference—don't guess, safety first! Smooth starts also save some fuel costs.

The speed in 1st, 2nd, and 3rd gears really depends on your car's engine power and weight. I remember once driving a friend's sports sedan—1st gear easily hit 20 km/h, 2nd gear zoomed to 40, and 3rd gear could go beyond 60, which was super thrilling. But it's different with my compact car: 1st gear tops out around 10 km/h at launch, 2nd gear barely exceeds 20, and 3rd gear feels right at 30-40. Many factors come into play, like tire size and road gradient. I’d suggest keeping an eye on the tachometer—don’t let it linger in the red zone too long, or you’ll waste fuel and strain the engine. Running at high speed in a low gear is risky; if the engine pressure warning lights up, pull over and shift immediately! Regular transmission maintenance is crucial.

When I first learned to drive, my instructor taught me not to be too rigid with the 1-2-3 gear speeds: 1st gear is for starting, keep it between 0-10 km/h, shift as soon as the car moves; 2nd gear is for acceleration between 10-20 km/h; 3rd gear is ideal for cruising at 20-40 km/h. Every car is different—smaller cars might need lower speeds, while larger vehicles might handle higher ones. The key is to listen to the engine; if it's roaring too loudly, it's time to upshift. With practice, you'll naturally get the hang of it—don't stress!
