The 2003 Nissan Murano requires Nissan CVT Fluid NS-2 for its first-generation Xtronic CVT transmission. Do not use conventional ATF, as Dexron/Mercon-type fluids can damage the CVT.
Overview of the fluid requirement for the 2003 Murano
The Murano’s 2003 model year uses a continuously variable transmission (CVT) rather than a traditional automatic transmission. CVTs need a specialized fluid designed for their friction materials and temperature characteristics. NS-2 is the standard Nissan CVT fluid specified for this vehicle; using the wrong fluid can lead to slipping, overheating, and transmission wear. NS-2 is typically available from Nissan dealerships, certain auto parts stores, and reputable online retailers. Always check the product label to confirm it is NS-2 and intended for CVT use.
Where to source Nissan CVT Fluid NS-2 for your 2003 Murano:
- Nissan dealership or official parts retailer, which provides the genuine NS-2 spec.
- Authorized auto parts stores that stock Nissan CVT fluid labeled NS-2 for CVTs.
- Online retailers or marketplaces with clear product labeling; verify NS-2 compatibility before purchase.
In addition, note that Nissan later introduced NS-3 for certain newer CVT applications, but the 2003 Murano should use NS-2. If you are unsure, consult the owner's manual or a Nissan service center to confirm compatibility with your VIN and transmission model.
Maintenance and service considerations
When servicing the CVT fluid, follow the maintenance schedule in the owner's manual and have a qualified technician perform the replacement. CVT fluid changes are more nuanced than standard automatic transmissions, and incorrect fill amounts or using the wrong fluid can harm performance. Always use NS-2 for this model and avoid mixing fluids. If doing a DIY drain/fill, ensure you follow Nissan’s procedure and proper safety practices, or seek professional help to prevent transmission damage.
Summary
The 2003 Nissan Murano uses Nissan CVT Fluid NS-2 for its Xtronic CVT transmission. Use NS-2 exclusively, sourced from Nissan dealers or reputable retailers, and follow the official maintenance guidance to preserve transmission longevity. For any doubt about your VIN or vehicle-specific requirements, consult the owner's manual or a Nissan-certified service center.
