The 2009 Nissan Murano with a CVT transmission holds about nine quarts of transmission fluid when fully topped up. If you replace the transmission filter during service, the total can be closer to about 9.5 quarts.
Official capacity for the Murano's CVT
Nissan’s service data for the Murano’s CVT (the RE0F10A-style unit used in the 2009 model year) lists a total fluid capacity in the neighborhood of 9.0 to 9.5 quarts. This figure represents a full fill when the system is at operating temperature and reflects a standard service that may include filter replacement. Individual vehicles and service procedures can lead to slight variations.
What changes with filter replacement
Replacing the CVT fluid filter typically brings the total required fluid closer to the higher end of the capacity range. Without changing the filter, the amount needed is usually a bit lower, though exact figures depend on the service method and whether any additional flushing steps are performed.
Practical considerations for owners and technicians
Always use CVT fluid that meets Nissan specifications for your Murano’s year. Using traditional automatic transmission fluid can cause improper clutch engagement and accelerated wear in CVTs. If you’re unsure of the exact amount, consult the owner's manual or a Nissan service center, as some models have no dipstick and level is checked by a specified service procedure with the vehicle warm.
Summary
For a 2009 Murano with a CVT, plan on roughly 9 quarts of CVT fluid for a full fill, with about 9.5 quarts if the transmission filter is replaced during service. Verify exact amounts with the service manual or your mechanic and use Nissan-approved CVT fluid to protect the transmission.
