Parts for your 2000 Nissan Navara-Transmission filter

2000 Nissan Navara transmission filter — what’s fitted and what to service

For the 2000 Nissan Navara (D22), whether a transmission filter is relevant depends on the gearbox. Factory technical references confirm that manual gearboxes (FS5W71 series) have no serviceable transmission filter, relying instead on magnetic drain plugs and periodic oil changes. In contrast, the 4‑speed automatic used in many D22s (Jatco/Nissan RE4R01A) does have an internal oil strainer and pan gasket. This is documented in the Nissan D22/Frontier Factory Service Manual (automatic transmission section) and in Jatco RE4R01A service literature, both of which depict a replaceable strainer inside the transmission pan. Nissan dealer schedules in AU/NZ also note fluid inspection/replacement for the auto, with the strainer serviced when the pan is off or if contamination is present.

For owners of an automatic 2000 Navara, the transmission filter (often called a strainer) plays a quiet but crucial role. It sits inside the transmission pan and screens out clutch material, fine metal and debris from the ATF so the hydraulic control system and torque converter can do their jobs smoothly. A healthy strainer helps prevent shift flare, harsh engagement and premature wear of the valve body and pump.

While many factory schedules don’t list a strict interval for changing the strainer, real‑world servicing in Australia and New Zealand treats it as a pan‑off service item. That’s the ideal time to replace the pan gasket, clean the magnets, inspect the sediment, and fit a new strainer if it’s dirty, damaged or restricted. If the ATF is dark, smells burnt, or there are shifting niggles, it’s a strong cue to drop the pan rather than just doing a quick drain-and-fill.

A sensible plan for the auto D22 is to refresh the ATF every 40,000–60,000 km if it tows, sees hot climates, beach work or stop‑start duties, and to schedule a pan‑off service (with strainer and gasket) around 80,000–100,000 km or sooner if contamination is found. Always use the specified ATF type for the RE4R01A era (commonly Dexron III/Matic‑D equivalent), and avoid power flushing on high‑km units with unknown history—multiple gentle drain‑and‑fills are kinder.

Handy tips when the pan’s off:

• Replace the pan gasket, torque bolts evenly, and clean magnets thoroughly.
• Check the old strainer for debris load, heavy sediment suggests more frequent ATF changes.
• Reset fluid level hot and idling, on level ground, following the FSM procedure.

Manual D22 owners can ignore filters entirely, just use the correct manual gearbox oil and change it on time—those magnets do the catching.

Popular questions

Does a manual 2000 Navara have a transmission filter?
Manual D22 gearboxes don’t use a serviceable transmission filter. They rely on the correct gear oil and a magnetic drain plug to capture fine metal. Stick to the recommended oil and change intervals and it’ll be happy.

How often should the automatic Navara’s transmission filter be changed?
There’s usually no fixed interval in the factory schedule, but it’s wise to replace the strainer whenever the pan is removed for service. Many workshops in AU/NZ plan a pan‑off service with strainer and gasket at roughly 80,000–100,000 km, or sooner if the ATF is discoloured or there are shifting issues.

What ATF should be used in the 2000 Navara auto?
The RE4R01A automatic of that era typically specifies Dexron III/Matic‑D type fluid. Use a quality equivalent that meets those specs. After any pan‑off service, set the level carefully at operating temperature as per the Nissan FSM.
