Parts for your 2005 Nissan Navara-Transmission filter

2005 Nissan Navara transmission filter — what’s fitted and how to look after it

For a 2005 Nissan Navara with an automatic gearbox (common units include the 5‑speed RE5R05A in D40 and the 4‑speed RE4R01A in late D22), there is a transmission oil filter — it’s an internal strainer mounted inside the sump pan. This is confirmed by Nissan factory service manuals for D40/D22 (AT section), Jatco RE5R05A service literature, and Nissan parts catalogues that list an “oil strainer” for these autos. Manual Navaras of the same year don’t use a transmission filter, they run gear oil and rely on a magnetic drain plug, so a filter isn’t relevant to manuals.

On the autos, the transmission filter’s job is simple but critical: it screens out clutch material and fine debris so the hydraulic circuits and solenoids get clean ATF. Clean fluid and a healthy strainer help maintain crisp shifts, reduce wear, and keep transmission temps in check — a big deal if the ute tows, tours, or sees dusty outback work.

While Nissan’s official maintenance schedules often focus on fluid condition rather than routine filter swaps, many Aussie and Kiwi workshops recommend a sensible service approach: if the pan’s coming off, replace the strainer, the pan gasket, and clean the magnets. For vehicles that tow, do beach work, or operate in hot or hilly conditions, consider a pan‑off service at roughly 100,000–120,000 km, or sooner if there are signs of contamination. Otherwise, periodic ATF drain‑and‑fills (every 40,000–60,000 km under severe use) help keep the filter from being overloaded and the fluid from shearing down.

Use the correct fluid: RE5R05A units specify Nissan Matic J (superseded by Matic S), and RE4R01A generally specifies Matic D — always check the build plate and the FSM for your exact spec and don’t mix types. When replacing the strainer, make sure the old O‑ring comes out with it, seat the new one cleanly, and torque pan bolts evenly to avoid warping. After reassembly, set the fluid level following the FSM temperature and level procedure, level is critical on these boxes.

If the Navara shows flaring shifts, delayed engagement, shudder, or dark, burnt‑smelling ATF, don’t leave it — book it in. Catching contamination early and renewing ATF, the internal strainer, and the pan gasket can save a good transmission from becoming an expensive rebuild.

• Technical references used: Nissan Navara D40/D22 Factory Service Manuals (AT section), Jatco RE5R05A service information, Nissan maintenance schedules for Australian conditions, and Nissan parts catalogues listing the internal oil strainer for RE5R05A/RE4R01A.

Popular questions

Does my 2005 Navara definitely have a transmission filter?
If it’s an automatic, yes — an internal oil strainer inside the transmission pan. If it’s a manual, no filter is used, just change the gearbox oil on schedule and clean the magnetic plug.

How often should the transmission filter be replaced?
There’s no strict interval in many factory schedules, but a pan‑off service with a new strainer around 100,000–120,000 km is a solid practice in ANZ conditions, sooner if the fluid is dirty, you tow regularly, or you notice shifting issues.

Which ATF should be used in a 2005 Navara auto?
Most D40 RE5R05A units use Nissan Matic J (now commonly serviced with Matic S). Some D22 RE4R01A units specify Matic D. Always confirm by VIN/build info and the factory manual before buying fluid.
