Parts for your 2011 Nissan Navara-Transmission fluid

2011 Nissan Navara transmission fluid – what it does and when to change it

Transmission fluid is absolutely relevant to the 2011 Nissan Navara (D40). According to Nissan’s D40 Owner’s Manual and Service Manual, the 5‑speed automatic (RE5R05A) uses Nissan Matic S ATF, while the 6‑speed manual (FS6R31A) uses a GL‑4 75W‑85 manual transmission oil. Those technical sources are clear that both auto and manual Navaras rely on the correct fluid for cooling, lubrication, hydraulic control (auto) and smooth shifting.

For an automatic Navara, transmission fluid does three big jobs: it acts as a hydraulic medium to apply clutches and bands, reduces wear on gears and bearings, and carries heat to the cooler. Fresh, correct‑spec ATF (Nissan Matic S) helps keep shifts crisp and prevents shudder when towing, touring, or commuting. Expect around 4–5 litres on a typical drain‑and‑fill service, with a full dry fill closer to 9–10 litres. The RE5R05A features a dipstick, so level checks are done hot, in Park, with the engine idling.

For the manual, the fluid is a dedicated GL‑4 75W‑85 gear oil. It cushions the synchros, cuts down on notchiness, and protects the gears under load. Capacity is roughly 2.2–2.5 litres depending on variant. Using GL‑5 in place of GL‑4 isn’t advised, as the different additive pack can be harsh on synchro materials.

Service timing depends on use. While Nissan schedules often list inspection rather than fixed replacement for normal conditions, workshops across Australia and New Zealand commonly recommend changing ATF about every 60,000 km (or sooner if you tow, drive in heat, or do lots of stop‑start). Manual gear oil responds well to a 60,000 km refresh too, especially if shifts feel notchy when cold. If the fluid looks dark, smells burnt, or has glittery debris, don’t push it—replace it.

• Use only Nissan Matic S for the auto RE5R05A, avoid mixing brands or specs.
• Use GL‑4 75W‑85 for the FS6R31A manual, fill to the level plug on level ground.
• Remember: transfer case and diffs have separate oils on 4x4 models.

Sticking to the right fluid and sensible intervals keeps the Navara shifting sweetly and protects the driveline, whether it’s hauling gear for work or heading off for a weekend away.

Which transmission fluid does my 2011 Navara need?

Automatic (RE5R05A): Nissan Matic S ATF. Manual (FS6R31A): API GL‑4 75W‑85 manual transmission oil. If unsure, check the build plate and owner’s manual, or match by VIN at a trusted parts counter.

How often should the transmission fluid be changed?

Many local workshops recommend about every 60,000 km for both auto and manual, sooner for heavy towing, beach work, or hot climates. Always inspect colour and smell—burnt or dirty fluid means it’s time.

What are signs the fluid needs attention?

Auto: flare between shifts, harsh engagement, shudder, or overheating warnings. Manual: notchiness, crunching into gears, or whining. Any metallic glitter or burnt smell in the drained fluid is a red flag.
