Parts for your 2002 Nissan Navara-Transmission filter

2002 Nissan Navara transmission filter: what’s fitted and how to look after it

Technical sources including the Nissan Navara D22 Series Service Manual (2002, Automatic Transmission [AT] section), the Jatco RE4R01A overhaul information used for the D22 auto, and the D22 Manual Transmission (MT) service section confirm the following: 2002 Navara manuals do not use a transmission filter at all, the automatic variants use an internal pan-mounted suction strainer (often called a “screen”), not an external spin-on filter. The MT section specifies only oil changes and magnet cleaning, while the AT section shows the strainer within the sump alongside service procedures for pan removal and cleaning. That means a transmission filter is relevant only for automatic-equipped 2002 Navaras.

On automatic 2002 Navara models, the transmission filter’s job is to protect the pump, valve body and solenoids by catching clutch material and fine metal worn from normal operation. It helps the fluid stay clean, so shifts remain crisp and the box runs cool. In the D22 auto it’s a pan-mounted mesh strainer rather than a replaceable spin-on cannister, and it’s serviced when the sump is removed.

As part of routine servicing, it’s smart to refresh the ATF at about 40–60,000 km in normal use, or sooner if the ute tows, sees lots of stop–start, or spends time off-road in heat. A drain-and-fill replaces roughly 3–4 litres, the full system holds around 8–9 litres, so multiple drain cycles or a proper service are needed to renew most of the fluid. Use the fluid specified in the factory manual for this era (typically Nissan Matic-D/Dexron III equivalent) and set the level hot, engine idling, after cycling through the gears.

Every 100,000–150,000 km—or whenever there are symptoms—drop the pan, clean the magnets, fit a new gasket and inspect the strainer. Many techs replace the strainer as cheap insurance, if it’s the metal-mesh type in good nick, some workshops will clean it and refit with a fresh O-ring. Refit the pan evenly and torque the bolts to the workshop spec to avoid warping. Signs the strainer is overdue include delayed engagement, shift flare, slipping on hills, or ATF that smells burnt or looks glittery. If the vehicle is manual, none of this applies—there’s no filter, just periodic gearbox oil changes and magnet cleaning per the MT section.

• Best practice: fluid every 40–60,000 km, pan, magnets and strainer service around 100,000–150,000 km, sooner for heavy towing or dusty, hot conditions.
• Always match ATF to the spec in the service manual and verify level at operating temperature.

Does a 2002 Navara have a transmission filter?

Manual D22s don’t have one. Automatic D22s do—it’s an internal pan-mounted strainer inside the transmission sump. It’s serviced when the pan is removed, not as a quick external swap.

How often should the automatic transmission filter be serviced or replaced?

Change the ATF about every 40–60,000 km and plan a pan-drop with magnet clean and strainer inspect/replace roughly every 100,000–150,000 km. If the ute tows, works hard, or shows symptoms like delayed engagement or burnt fluid, bring that forward.

What transmission fluid should be used and how much does it take?

Use the fluid specified by Nissan for the D22 auto of this era (commonly Nissan Matic-D/Dexron III equivalent). A simple drain-and-fill will return about 3–4 litres, total capacity is around 8–9 litres, so multiple services or a full pan service may be needed to refresh most of the fluid. Set the level hot, engine idling, after shifting through all ranges.
