What is the impact of climbing hills during the break-in period of an automatic transmission new car?

Climbing hills during the break-in period of an automatic transmission new car has no significant impact. However, it is essential to avoid high-speed driving and long-distance fully loaded trips during this period. Do not let the engine's RPM get too high—generally, it should not exceed 3,000 RPM. Otherwise, it may cause carbon buildup in the engine, making the car harder to start, resulting in poor acceleration and increased fuel consumption. Precautions for the break-in period of an automatic transmission new car include: 1. Maintain smooth starts, avoid sudden acceleration, and do not let the engine RPM get too high; 2. Ensure the coolant temperature reaches at least 50°C before starting; 3. Start in a low gear and shift to a higher gear after one kilometer, keeping the coolant temperature between 80°C and 90°C while driving; 4. Choose good road conditions to avoid excessive vibration, impact, or emergency braking. Before braking, disengage the clutch first; 5. Use high-quality fuel and engine oil, and avoid using engine wear-resistant additives.
I remember when I drove my new car, the break-in period did have some impact on climbing hills. Automatic transmission vehicles put more load on the engine and transmission when going up steep slopes, and since the parts are still in the wearing-in phase, it might accelerate wear or cause overheating. For example, during my last trip to the mountains, my car struggled a bit—I had to press the accelerator deeper, and the system shifted gears more frequently. I recommend that beginners avoid challenging too steep slopes and instead choose gentler inclines to climb slowly. Additionally, keep an eye on the engine temperature gauge and stop immediately if you notice anything unusual. The break-in period is roughly the first 500 to 1,000 kilometers—avoid prolonged high-load operation during this time, as it helps extend the car's lifespan. After the first maintenance service, you can confidently tackle steep slopes, as the parts will have settled in more smoothly, making driving much easier.
