Parts for your 2010 Nissan Navara-Transmission filter

2010 Nissan Navara transmission filter — what it is and when it matters

Technical references confirm the 2010 Nissan Navara (D40) automatic does use a transmission filter — an internal “oil strainer” mounted inside the sump/pan on the Jatco RE5R05A 5‑speed and the JR710E/RE7R01A 7‑speed gearboxes. This is documented in the Nissan D40 Navara Factory Service Manual (Automatic Transmission sections for RE5R05A and JR710E/RE7R01A), Jatco service data for the RE5R05A, and Nissan’s parts catalogues listing the oil strainer assembly. Manual (stick‑shift) Navaras don’t have a transmission filter, as their gearboxes run on gear oil without inline filtration.

On auto models, the transmission filter’s job is simple but vital: it screens out clutch material and fine debris from the automatic transmission fluid (ATF) so the valve body and solenoids keep working smoothly. Unlike an engine oil filter, this one is a flat internal strainer bathed in ATF, and it isn’t called out as a routine replacement item in Nissan’s scheduled servicing. Instead, the service focus is on fluid condition and level.

For day‑to‑day servicing, the smart play is to change the ATF at sensible intervals based on use — typically every 60,000–90,000 km in Australian and New Zealand conditions, sooner if the Navara tows, sees lots of off‑road work, or lives in hot climates. During a fluid service, dropping the pan lets a technician inspect for debris, clean the magnets, and gauge clutch wear. If there’s notable contamination, replacing the internal strainer and the pan gasket is a good preventative step.

Most D40 autos don’t have a dipstick, fluid level is set at a specific temperature via the level plug. Use the correct ATF — Nissan Matic J or its supersession Matic S for the RE5R05A, and Matic S for the 7‑speed — and follow the factory procedure to check level around 35–45°C. The right fluid and level matter more to shift quality and transmission life than repeatedly swapping the filter.

Replace the transmission filter when there are symptoms of debris‑related restriction or as part of a rebuild. Telltales that warrant pan removal and closer inspection include:

• Delayed engagement, flare on upshifts, or harsh shifts
• Shudder under light throttle
• Excess metallic fuzz on pan magnets or visible sludge in the sump

There’s no external spin‑on filter from factory on the D40 auto, it’s all internal. Sticking to quality ATF, correct level setting, and pan inspections when servicing will keep the Navara’s auto happy for the long haul.

FAQs

Does a 2010 Navara have a transmission filter?
Yes, the automatic versions do — it’s an internal oil strainer inside the transmission pan on both the 5‑speed RE5R05A and the 7‑speed JR710E/RE7R01A. Manual transmissions don’t have a filter. This layout is outlined in the Nissan D40 Navara Factory Service Manual and Jatco technical data.

How often should the transmission filter be replaced?
It’s not a routine service item. The filter is typically replaced during an overhaul or if pan inspection shows significant debris. Focus on timely ATF changes (about 60,000–90,000 km depending on use), and inspect the pan, magnets, and strainer condition when the sump is off.

Which ATF should be used, and how is the level checked?
Use Nissan Matic J or Matic S for the 5‑speed RE5R05A (Matic S often supersedes J), and Matic S for the 7‑speed. Most D40 autos are “sealed” and use a level plug, the fluid level is set with the transmission at a specified temperature (roughly 35–45°C) following the factory procedure.
