2007 Nissan Navara transmission filter: what’s fitted and how to look after it

Per Nissan technical literature for the D40 Navara (Factory Service Manual, AT section for the RE5R05A automatic) and the Nissan FAST parts catalogue, the 2007 Navara automatic uses an internal transmission oil strainer inside the pan, not an external spin-on filter. Manual Navara gearboxes don’t run a transmission filter at all. The FSM notes the strainer as a non-routine service item, while the parts catalogue lists it as an “oil strainer” under the 31728 prefix. That means “transmission filter” is relevant for the auto variants, but it’s a pan-off component rather than a quick-change filter.

For owners of a 2007 Nissan Navara with the 5‑speed auto, the transmission filter (strainer) plays a quiet but important role. Sitting just above the sump pan, it screens the automatic transmission fluid (ATF) as the pump draws it in, catching clutch material and other fine debris before it can circulate through the valve body and solenoids. Magnets in the pan help by trapping ferrous particles, while the strainer looks after the rest, keeping shifts consistent and hydraulic circuits happy.

Because it’s a metal-mesh style strainer, Nissan doesn’t list it as a regular service item in the schedule. In real-world Aussie and Kiwi conditions—think towing, tradie loads, heat and dust—it’s smart to treat ATF as a consumable and the strainer as inspect/replace when the pan’s off. Many workshops recommend an ATF service every 60,000–90,000 km under severe use, or longer intervals for light duty. When dropping the pan, clean the magnets, inspect the old fluid and sediment, and replace the pan gasket. If there’s noticeable debris, burnt fluid, or high kilometres on the clock, fitting a new strainer is cheap insurance.

Stick with the correct fluid: Nissan Matic J was the original spec for the RE5R05A, with Matic S the common supersession. Use a high-quality, compatible full-synthetic ATF if not using genuine. Avoid aggressive power flushing on high‑km units, a measured pan drain, filter/strainer replacement and refill is kinder. Set the fluid level exactly as per the FSM—temperature matters. Some D40s have a dipstick, others use a check/overflow plug method, either way, the level is checked at a specified ATF temperature range.

Good times to replace the strainer include:

• Any time the pan is off for servicing or repairs
• After overheating, contaminated ATF, or water ingress
• When shift quality issues suggest restricted flow
• During a rebuild or valve body service

Manual 2007 Navaras are different beasts: no ATF, no filter—just gear oil. For them, it’s a simple drain-and-fill at the recommended interval with the correct spec oil.

FAQs

Does a 2007 Nissan Navara have a transmission filter?
Yes for the automatic: it has an internal oil strainer inside the transmission pan. There’s no external spin‑on filter. Manuals don’t use a transmission filter.

How often should the transmission filter be changed on a 2007 Navara?
It isn’t a routine change item by the book, but many workshops replace the strainer whenever the pan is removed—especially if there’s debris, burnt ATF, or high kilometres. Plan ATF servicing around 60,000–90,000 km for heavy use.

What transmission fluid does the 2007 Navara auto use?
Nissan Matic J was the original spec, Matic S is the typical supersession. Use a high‑quality, compatible full‑synthetic ATF if not using genuine, and set the level at the correct temperature per the FSM.
