Nissan recommends changing the CVT fluid every 30,000 miles under severe driving conditions (e.g., frequent towing, stop-and-go traffic) or every 60,000 miles under normal driving conditions. However, many mechanics recommend changing the fluid more frequently, especially if you notice any signs of transmission problems. When changing the fluid, it's important to use the correct type of CVT fluid. Nissan CVTs require a specific fluid type (usually Nissan CVT Fluid NS-2 or NS-3) to ensure proper performance and prevent damage. Using the wrong fluid can lead to serious transmission problems. In addition to fluid changes, it's also important to check the transmission fluid level regularly. A low fluid level can indicate a leak and should be addressed promptly. The fluid level should be checked with the engine running and the transmission at operating temperature. Another key maintenance task is replacing the transmission filter. The filter removes contaminants from the fluid, preventing them from circulating and causing wear. The filter should be replaced at the same time as the fluid change. Avoid aggressive driving habits such as hard acceleration and sudden stops. These habits put excessive strain on the transmission and can accelerate wear. Smooth, controlled driving is much easier on the transmission. Regular inspections by a qualified mechanic can also help identify potential problems early on. A mechanic can check for leaks, inspect the transmission cooler lines, and assess the overall condition of the transmission. By following these maintenance tips, you can help ensure the long-term health and performance of your 2009 Nissan Murano's transmission and avoid costly repairs.
