How often should the transmission fluid of the Sylphy be changed?

[LaLondyn]

Nissan Sylphy Classic requires transmission fluid replacement every two years or 40,000 kilometers, with approximately 3 liters needed for refilling. Below are the hazards of not changing the transmission fluid on time: 1. Failure to replace the transmission fluid on time will have adverse effects, whether it's a manual or automatic transmission. The vehicle may experience weak starts during cold starts; operating at high speeds and temperatures can cause the fluid to degrade and evaporate, thereby accelerating wear and even damage to mechanical components. 2. The transmission fluid will thicken, making it easier for the transmission cooler to become obstructed, leading to excessively high transmission fluid temperatures and increased wear. During driving, the vehicle may experience slipping, reduced control precision, and poorer shift accuracy, affecting the smoothness and responsiveness of the vehicle.
