What are the maintenance methods for a CVT transmission?

[LeJayden]

Maintenance methods for a CVT transmission include: 1. Do not shift the gear lever to the N position while driving; 2. When changing from forward to reverse or from reverse to forward, ensure the vehicle is completely stopped, and operate the gear lever while pressing the brake pedal to avoid potential damage to the transmission; 3. When going downhill, use the S position or the manual mode's low gear to utilize engine braking, preventing brake pad heat fade and reduced braking performance from prolonged braking; 4. Due to the structure and working principle of CVT transmissions, all controls are managed through internal hydraulic pressure; 5. To improve fuel economy, the automatic mode of the CVT transmission can be used while driving; 6. Because of the CVT's design, if related components or circuits are serviced or disconnected, a special internal reset procedure is required to restore the CVT to normal operation.

I've been driving a CVT car for several years, and the core of maintenance is regular transmission fluid changes. The specialized CVT fluid needs to be replaced every 60,000 to 80,000 kilometers; otherwise, degraded fluid can cause chain slippage and accelerated wear. Driving habits are also crucial—avoid frequent hard acceleration or sudden braking, as gentle starts help protect internal components. Regularly check the fluid level, and replace it immediately if it turns black or has a burnt smell. In cold weather, let the car warm up for a few minutes before driving to prevent low-temperature damage. I also schedule regular shop visits to inspect the cooling system, as transmission overheating is a major enemy. With good habits, a CVT can last over a decade without issues, saving both money and hassle.

CVT maintenance isn't that complicated, the key expenditure is fluid replacement. Follow the manual - most vehicles only need CVT fluid changes every 60,000-100,000 km. I use OEM fluid to avoid compatibility issues. Drive gently without aggressive acceleration/braking to protect the transmission chain. While fluid is inexpensive, don't skip changes - degraded fluid causes shift hesitation and abnormal noises. Occasionally check fluid level and color. Keep the vehicle clean for better heat dissipation, and avoid long trips in summer heat to prevent overheating. This routine maintenance saves time and extends lifespan.

The CVT structure relies on hydraulics and a chain to adjust the gear ratio, so maintenance should focus on fluid management. Special CVT fluid must be used to maintain lubrication and cooling, with regular changes to prevent wear. Avoid aggressive driving to reduce chain load. Monitoring oil temperature is crucial, especially in summer when more breaks are needed for cooling. Address any discoloration or sedimentation in the fluid immediately—don't wait for unusual noises to appear. Ensure the overall health of the vehicle to minimize additional stress.
