Parts for your 2007 Nissan Maxima-Transmission fluid

2007 Nissan Maxima transmission fluid: what it does and how to look after it

Transmission fluid absolutely applies to the 2007 Nissan Maxima. Nissan’s own technical literature – the 2007 Owner’s Manual and the Factory Service Manual (CVT and Automatic Transaxle sections) – specifies dedicated transmission fluid for this model. Depending on market and trim, the 2007 Maxima was fitted with either Nissan’s Xtronic CVT, which requires Genuine Nissan CVT Fluid NS-2, or a conventional automatic that calls for Genuine Nissan Matic ATF (typically Matic J/K as labelled under the bonnet and in the manual). Either way, fluid is essential for lubrication, hydraulic control, cooling, and smooth shifting.

In day-to-day driving, good fluid keeps the Maxima’s gearbox happy by reducing wear, carrying heat away, and maintaining the correct clutch engagement feel. Over time, heat, oxidation, and shear break the fluid down. In CVTs especially, fluid quality is critical because it grips the belt and pulleys, the wrong fluid or neglected changes can quickly lead to shudder, flare, or metal wear.

For maintenance, a sensible approach in Australian and New Zealand conditions is to inspect the fluid condition around every 40,000–60,000 km and plan a change between 60,000–90,000 km, sooner if the car tows, idles in heavy traffic, or sees hot climates. Nissan’s service information also notes that CVT fluid health can be assessed with a scan tool via the “fluid deterioration” value, after a CVT service, a technician should reset that counter. Avoid power-flushing a CVT, a measured drain-and-fill (often repeated) is the safer method. On CVT units, level is checked at a specific fluid temperature range, so it’s a job best done with the right equipment. For conventional automatics, a periodic drain-and-fill with the specified Matic fluid maintains shift quality without shocking the system.

• Use only the fluid type specified: NS-2 for CVT, the correct Nissan Matic ATF for 5-speed autos.
• Do not mix ATF and CVT fluid — they’re not interchangeable.
• Replace the crush washer on the drain plug and torque to spec to prevent leaks.
• If in doubt about which transmission is fitted, check the build plate, owner’s manual, or consult a technician.

Looked after this way, a 2007 Maxima’s transmission stays smooth, quiet, and reliable over big kilometres.

Popular questions about 2007 Nissan Maxima transmission fluid

What fluid type does a 2007 Maxima take?
Most 2007 Maximas use Nissan’s Xtronic CVT and must have Genuine Nissan CVT Fluid NS-2. Some markets received a 5‑speed automatic, those require the Nissan Matic ATF specified on the under‑bonnet label and in the Owner’s Manual (often Matic J/K). Using the wrong fluid can cause rapid wear and poor shifting.

How often should the transmission fluid be changed?
Plan a fluid service around 60,000–90,000 km, earlier if the vehicle tows, drives in hilly areas, or spends time in heavy traffic and heat. CVT models benefit from condition-based checks with a scan tool and fluid changes before deterioration gets high. Conventional autos respond well to periodic drain‑and‑fills.

Can ATF be used in the CVT, or mixed?
No. ATF and CVT fluid are not interchangeable. CVTs rely on the unique friction and shear characteristics of NS‑2. Mixing fluids can lead to shudder, slipping, metal debris, and costly transmission damage.
