Your Nissan Murano is a marvel of modern engineering, designed for comfort and capable performance on the road. At the heart of this smooth driving experience is the transmission, a complex system that works tirelessly to transfer power from the engine to the wheels. For it to perform its job flawlessly for years to come, it relies on a special fluid that lubricates, cools, and cleans its internal components. Over time, this fluid degrades, and neglecting it can lead to costly repairs.
Knowing the correct transmission fluid capacity for your Murano and understanding the procedure for changing it are two of the most valuable pieces of maintenance knowledge you can have. It’s not just about following a schedule; it’s about actively preserving the health and longevity of your vehicle. This guide will walk you through everything you need to know, from how much fluid your model requires to the steps for a successful fluid change.
How Much Transmission Fluid Does Your Murano Need?
The amount of fluid your Murano needs depends heavily on the model year and the specific transmission it uses. Nissan has employed different transmissions over the Murano’s generations, primarily the Continuously Variable Transmission (CVT) in newer models and a conventional automatic in earlier ones. Using the correct type and amount of fluid is non-negotiable.
For most third-generation Muranos (2015 and newer) equipped with the CVT, the total fluid capacity is approximately 9.5 to 10 quarts. However, during a standard drain and fill service—which is what most owners and even shops perform—you will only be able to replace about 4 to 5 quarts at a time. This is because a significant amount of fluid remains in the torque converter and internal passages, making a complete replacement difficult without specialized equipment.
For earlier first- and second-generation models with a conventional automatic transmission, the total capacity is typically around 9.5 quarts, with a drain and fill yielding roughly 4 quarts of old fluid. The most important step is to always consult your owner’s manual for the precise specification for your model year and trim. Using too much or too little fluid can be just as harmful as using the wrong type.
Choosing the Right Fluid for Your Murano
This is arguably the most critical part of the entire process. Using the incorrect transmission fluid can lead to poor performance, damage, and complete transmission failure. Nissan is very specific about the fluids required for its transmissions.
For Muranos with a CVT, you must use a genuine Nissan CVT fluid, specifically Nissan NS-3 CVT Fluid. This fluid is formulated with special additives and friction characteristics that are essential for the unique belt-and-pulley system inside the CVT. Using a generic automatic transmission fluid (ATF) will ruin the transmission.
For older models with a conventional automatic transmission, the required fluid is typically Nissan Matic S ATF or its successor, Nissan Matic K ATF. Again, your owner’s manual is the final authority. Sticking with genuine Nissan fluid or a high-quality equivalent that meets the exact Nissan specification ensures optimal performance and protects your investment.
A Step-by-Step Guide to a Transmission Fluid Drain and Fill
Performing a transmission fluid change is a manageable task for a confident DIYer. Always prioritize safety by working on a level surface, using jack stands, and wearing protective gear.
First, gather your supplies. You will need the correct type and amount of Nissan transmission fluid, a new transmission drain plug washer (often aluminum), a socket set, a fluid pump (to add the new fluid), a drain pan, safety glasses, and gloves.
Start with the vehicle on a level surface and the transmission at normal operating temperature. This ensures an accurate fluid level check later. Carefully place the drain pan underneath the transmission drain plug. Using the correct socket, loosen the drain plug and then carefully remove it by hand, being prepared for hot fluid to flow out. Allow the fluid to drain completely.
Once drained, clean the drain plug and replace the washer. Reinstall the plug and tighten it to the manufacturer’s specified torque. Now, locate the transmission dipstick tube. Using your fluid pump, slowly add new fluid through this tube. Start by adding about 3.5 to 4 quarts initially.
Next, you need to check the fluid level. With the parking brake firmly engaged, start the engine. Move the gear selector slowly through each position (P, R, N, D, etc.), pausing for a few seconds in each. Return to Park. While the engine is still running, pull out the transmission dipstick, wipe it clean, reinsert it fully, and then pull it out again to check the level. The fluid should be within the “HOT” crosshatch marks on the dipstick. Add fluid in small, incremental amounts, checking after each addition, until the level is correct. Be careful not to overfill.
Why a Simple Drain and Fill is Often the Best Approach
You may have heard about transmission “flush” services offered by quick-lube shops. For a Nissan Murano, especially one with a CVT, a simple drain and fill is generally the recommended and safer method. A flush uses a machine to force fluid through the system under pressure, which can potentially dislodge debris and cause it to lodge in sensitive valves and passages, leading to new problems.
A drain and fill is a gentler process. It replaces a significant portion of the degraded fluid with fresh fluid, restoring its protective properties without the risks associated with high-pressure flushing. For optimal results, some owners choose to perform a drain and fill every 30,000 to 60,000 miles, which helps gradually replace almost all of the fluid over time in a safe and controlled manner.
Final Thoughts on Maintaining Your Murano’s Transmission
Staying on top of your Murano’s transmission fluid service is one of the most impactful things you can do for its long-term health. It’s a straightforward maintenance task that prevents shifting issues, overheating, and premature wear. Remember to always use the exact fluid type specified by Nissan and to perform a drain and fill rather than a risky flush for the best results.
By knowing your Murano’s specific fluid capacity and following a careful procedure, you can ensure that your vehicle continues to provide the smooth, reliable performance you expect for many miles to come. Your transmission works hard for you; giving it the right fluid care is a simple way to return the favor.
