Does Using D Gear on a CVT Uphill Damage the Car?
2 Answers
Using D gear on a CVT uphill does not damage the car. The D gear can be used when driving uphill in forward gear, and some cars are specifically designed with D-1 and D-2 gears for steep uphill driving. When driving uphill in D gear, simply controlling the throttle with an automatic transmission is sufficient. Pressing the accelerator deeply will automatically force a downshift when power is insufficient, and the car will automatically upshift when speed increases. Additional Information: The following are maintenance precautions for automatic transmission vehicles: 1. Regularly check the automatic transmission fluid level to ensure it is normal: The method for checking automatic transmission fluid differs from engine oil. Engine oil is checked when the car is cold, while transmission fluid needs to be preheated to about 50°C. After shifting the gear lever through each gear for 2 seconds and placing it in the parking gear, the normal fluid level on the dipstick should be between the highest and lowest lines. If it is insufficient, promptly add the same quality of fluid. 2. Understand the replacement cycle for automatic transmission fluid: The internal control mechanisms of an automatic transmission are very precise with small tolerances, so most manufacturers recommend replacing the transmission fluid every two years or 40,000–60,000 kilometers. During normal use, the transmission fluid operates at around 120 degrees Celsius, requiring high-quality fluid and maintaining cleanliness.
Driving a CVT car uphill in D gear isn't as delicate as people think. I've been driving CVT cars for seven or eight years, often on mountain roads. As long as you don't keep the accelerator pressed for too long and let the tachometer hit the red zone, it's generally fine. Modern cars come with transmission protection programs that automatically adjust the steel belt pressure when the computer detects excessively high RPMs. However, when encountering long steep slopes, I prefer switching to L gear or manual mode - this prevents the engine from roaring too alarmingly and provides better power. Most importantly, remember to change the transmission fluid regularly during maintenance; that's far more crucial than worrying about uphill driving damaging your car.
