What should be paid attention to during the break-in period of an automatic transmission new car?

Precautions for the break-in period of an automatic transmission new car: 1. Warm up the car before starting. After starting the vehicle, it takes some time for the engine oil to fully lubricate all parts from the oil pan to the engine components; 2. The break-in period is divided into three stages. For the first 500 kilometers, try to drive at a speed of 60 to 70 km/h, with the engine speed not exceeding 2200 rpm for optimal performance; 3. Between 500 to 1000 kilometers, the speed can be increased to 90 to 100 km/h, with the engine speed kept below 2500 rpm for optimal break-in; 4. After 1000 kilometers, the speed can be increased to below 120 km/h, with the engine speed not exceeding 3000 rpm; 5. Never suddenly shift into P or R gear while driving an automatic transmission new car, as this can cause severe mechanical impact and may immediately damage the transmission.
When I first got my automatic transmission car, I was particularly concerned about the break-in period. Generally, you should drive gently for the first 1,000 kilometers or so. Try not to exceed 80 km/h, and avoid sudden acceleration or braking, as it can easily cause engine wear. Driving smoothly is ideal, even in stop-and-go city traffic. If you occasionally take the highway, don’t go too fast—let the transmission and engine components gradually adapt to each other. I also made sure not to rev the engine too high, and never coast in neutral with an automatic transmission, as it can damage the gearbox. Regularly checking the engine oil condition is important, and the first maintenance service is crucial—only after that does the car start running smoothly. A proper break-in leads to better fuel efficiency, fewer issues, and feels like raising a child with patience. A few years later, it pays off with hassle-free driving.
