In brief, the 2003 Murano with a CVT transmission requires about 9 quarts of Nissan CVT fluid NS-2 for a full fill. A standard drain-and-fill usually exchanges roughly 4–5 quarts, while a complete system flush can use most or all of the 9-quart capacity. Always verify the exact specification in the owner's manual or with a Nissan dealer.
Understanding the Murano's transmission
The 2003 Murano uses a continuously variable transmission (CVT) supplied by JATCO. It requires a dedicated CVT fluid (Nissan CVTF NS-2) rather than standard automatic transmission fluid. Using the wrong fluid can degrade performance and damage the CVT, so verify fluid type before topping up.
Why fluid specifications matter
CVT performance and longevity depend on proper lubrication and heat management. Using the correct NS-2 CVT fluid helps maintain belt life and smooth operation, while over- or under-filling can lead to slipping, overheating, or other issues. Always follow Nissan’s service guidance for your specific vehicle.
Capacity and service variants
Here are typical capacities you should expect for a 2003 Murano’s CVT, depending on how you service the unit:
- Total system capacity (full fill, including torque converter): about 9 quarts
- Drain-and-fill (pan drain only, no torque converter drain): about 4–5 quarts exchanged
- Complete flush (lines, cooler, and converter): up to around 9 quarts
Note: Real-world numbers can vary by drivetrain configuration, fluid brand, and service equipment. Always confirm with the owner's manual or Nissan service documentation and use the recommended CVT fluid NS-2.
Tips for service and accuracy
To help ensure a proper fill and level check on the CVT, keep these tips in mind:
- Use Nissan CVTF NS-2 or an equivalent approved CVT fluid. Do not substitute standard automatic transmission fluids.
- Check the level with the engine running and the transmission at operating temperature, following the manual’s procedure for Park/Neutral positions.
- Consider professional service if you’re unfamiliar with CVT fill procedures or if the vehicle has high mileage and potential debris in the fluid.
Maintaining the correct CVT fluid level and using the proper fluid are essential for reliability and performance over the Murano’s lifespan.
Summary
The 2003 Nissan Murano’s CVT typically requires around 9 quarts of CVT fluid NS-2 for a full fill. A drain-and-fill commonly exchanges about 4–5 quarts, while a full flush can use nearly the full capacity. Always use the recommended CVT fluid and consult the manual or a Nissan dealer for exact procedures and capacities for your vehicle.
