Parts for your 1999 Nissan Navara-Transmission fluid

1999 Nissan Navara transmission fluid

Transmission fluid is relevant to the 1999 Nissan Navara when it’s fitted with the automatic gearbox. According to the Nissan D22 Factory Service Manual (A/T section) and owner’s literature for this model, the 4-speed Jatco/Nissan automatic (RE4R01A) specifies Nissan Matic D or Dexron III–spec ATF. Manual D22 Navaras, by contrast, use manual transmission gear oil (API GL-4 75W-90) as noted in the Transmission (TM) section of the same service documentation, not automatic transmission fluid.

On an automatic 1999 Navara, the transmission fluid does a lot of heavy lifting: it lubricates moving parts, cools the transmission under load, and provides the hydraulic pressure that makes smooth shifts happen. Fresh, correct-spec ATF helps the ute shift cleanly, reduces wear on clutches and bands, and keeps heat in check when towing, off-roading or slogging through stop–start traffic.

For routine servicing, a sensible interval in Aussie and Kiwi conditions is every 40,000–60,000 km or 2–4 years, earlier if the vehicle tows, works hard, or sees dusty or hilly routes. Nissan’s period guidance for the D22 platform supports regular inspection and replacement under severe use. Use a quality Dexron III ATF (Nissan Matic D equivalent) for the RE4R01A, later Matic fluids (like Matic S) aren’t the right match for this older box.

Good workshop practice on a drain-and-fill includes replacing the pan gasket, cleaning the magnet, and servicing the filter/strainer where applicable. A single drain typically replaces only part of the total capacity, so some owners choose two or three drain-and-fills spaced a short drive apart to refresh more of the fluid. Always check the level hot, on level ground, with the selector cycled through the gears as per the factory procedure, and avoid overfilling. Pink/red, clean-smelling fluid is healthy, dark, burnt-smelling ATF points to overdue service or a potential fault.

Manual 1999 Navaras are different: they use GL-4 gear oil, not ATF. Using the wrong fluid in either transmission can cause shift problems and premature wear, which is exactly what proper spec fluid helps prevent. Sticking to the recommended fluid and regular changes keeps this D22 shifting sweetly and working hard for years.

• Watch for symptoms: delayed or harsh shifts, shudder, or dark/burnt fluid.
• Confirm the transmission type (auto vs manual) before buying fluid.
• After service, road-test and recheck the level warm.

Popular questions about 1999 Nissan Navara transmission fluid

What transmission fluid does a 1999 Nissan Navara automatic use?
Most 1999 D22 automatics (RE4R01A) call for Nissan Matic D or a high-quality Dexron III ATF. That’s the spec referenced in Nissan’s D22 service information for the automatic section. Manual gearboxes need GL-4 75W-90 gear oil instead, so don’t use ATF in a manual.

How often should the ATF be changed on a 1999 Navara?
As a rule of thumb for local conditions, every 40,000–60,000 km or 2–4 years is a safe bet, sooner for heavy towing, hot climates or off-road use. Nissan’s D22 guidance recommends more frequent service under severe conditions, so many workshops treat ATF as a regular maintenance item.

How much ATF does it take?
Total capacity is typically around 8–9 litres for the RE4R01A, but a standard drain-and-fill only replaces about 3–4 litres. Multiple drain-and-fills can refresh more of the system without using a machine flush. Always measure what comes out and refill gradually to the correct hot level.
