Parts for your 2002 Nissan Serena-Transmission filter

2002 Nissan Serena transmission filter — is it used?

For the 2002 Nissan Serena (C24), a replaceable transmission filter generally isn’t a thing. On the CVT-equipped models common to this year, Nissan/Jatco designed the RE0F06A “Hyper CVT” with an internal metal-mesh strainer and magnets inside the pan, and there’s no scheduled filter replacement. The factory information treats the strainer as a non-serviceable component, so a separate “transmission filter” part isn’t listed for routine servicing.

This isn’t an oversight — it’s how the transmission is engineered. The CVT’s high-pressure hydraulic circuits don’t like restriction, so rather than a paper filter that could clog, Nissan relies on a coarse internal screen, strong pan magnets to catch wear debris, and correct CVT fluid (NS-2) changes to keep things clean. If contamination is found, the service path in the manual is pan-off inspection/cleaning and, if necessary, repair or overhaul — not a simple filter swap.

There is a wrinkle: some C24 Serena variants in certain markets used a conventional 4-speed automatic (RE4F04B). Those have a pan strainer that can be replaced during a pan-drop service. If the transmission ID plate reads RE4F04B, a strainer and pan gasket are relevant. If it reads RE0F06A (CVT), there’s no external/replaceable filter in normal servicing.

Practical care for a 2002 Serena CVT that doesn’t use a serviceable filter looks like this:

• Use only Nissan CVT Fluid NS-2. Don’t mix fluids.
• Perform drain-and-fill intervals around 40–60,000 km (or sooner if towing, hot climate, or stop–start use).
• When appropriate, remove the pan, clean the magnets and pan, inspect the internal screen, and renew the pan gasket/O-rings.
• Check the cooler lines and radiator cooler for condition and cleanliness, flow restrictions are bad news for CVTs.
• If an aftermarket inline cooler filter has been added, maintain/replace that per the kit maker — it’s not an OE part.

Technical references that support this include: Nissan Serena (C24) Factory Service Manual — AT/CVT sections specifying the RE0F06A internal strainer as non-serviceable and showing no periodic filter replacement, Nissan FAST electronic parts catalogue listings that omit a service filter for CVT variants while listing a pan strainer for RE4F04B, and Jatco RE0F06A service information describing internal mesh screening and magnetic debris control rather than a replaceable filter.

FAQs

Does the 2002 Nissan Serena have a replaceable transmission filter?
Most 2002 Serena C24 models with the RE0F06A CVT don’t have a replaceable filter. They use an internal strainer and pan magnets. Some 4-speed auto (RE4F04B) variants do have a serviceable pan strainer — check your transmission ID tag to be sure.

How should the transmission be serviced if there’s no filter?
Stick to CVT Fluid NS-2, do periodic drain-and-fills (about every 40–60,000 km under normal Aussie/NZ use), and when needed, remove the pan to clean magnets and inspect the internal screen. Also ensure the cooler lines and radiator cooler aren’t restricted.

What fluid does the 2002 Serena CVT use and how much?
It uses Nissan CVT Fluid NS-2. A basic drain-and-fill typically replaces a portion of the total capacity — the amount varies with procedure, but expect several litres. For exact specs and refill procedures, follow the factory manual for the RE0F06A and measure fluid temperature when setting the level.
