Parts for your 2005 Honda Fit-Transmission filter

2005 Honda Fit (Jazz) transmission filter – what’s actually fitted

For the 2005 Honda Fit (known as the Jazz in Australia and New Zealand), a traditional, user‑replaceable transmission filter isn’t part of normal servicing. Two gearboxes were common in AU/NZ: the 5‑speed manual and Honda’s CVT. The manual uses no filter at all, and the CVT uses an internal strainer and magnets rather than a replaceable external filter.

Technical references back this up. The Honda Fit/Jazz GD service manual (2002–2008) covers CVT fluid changes and overhauls, showing a fine‑mesh internal strainer and a magnetic drain plug to capture wear debris, with no external filter change step. Honda’s parts catalogues for GD1/GD3 likewise list a CVT strainer inside the case and do not show a separate, replaceable transmission filter for routine service. Honda service literature for HMMF/CVT‑F also focuses on correct fluid type and drain‑and‑fill intervals rather than filter replacement.

Why Honda didn’t use a serviceable filter here comes down to design and reliability. The CVT’s hydraulic circuits are sensitive to pressure and flow, adding an external filter can introduce restriction and aeration risk. Instead, Honda relies on an internal pickup screen to protect the pump and valve body, plus magnets that trap metallic fuzz. When paired with regular fluid changes using the specified CVT fluid, this setup keeps the unit clean without the need for a field‑serviceable filter. The manual gearbox is even simpler: quality MTF and case magnets do the housekeeping, there’s no filter by design.

What should owners do instead of a filter change? Keep on top of fluid service:

• CVT: Use the Honda‑specified CVT fluid (HMMF/CVT‑F as per the GD spec and local parts guidance). Many workshops in AU/NZ recommend a drain‑and‑fill every 40,000–60,000 km or 2–3 years, sooner if the car tows, does lots of short trips, or lives in hot city traffic.
• If the fluid comes out dark or the CVT shudders on take‑off, consider repeating a drain‑and‑fill after a few hundred kilometres to dilute old fluid further. Avoid power flushing.
• Manual: Replace MTF at the recommended interval, there’s no filter to change.

If contamination is severe or there are drivability issues that fresh fluid doesn’t fix, the internal strainer can be inspected or replaced during transmission repair—but that’s a workshop‑level job, not normal maintenance.

FAQs

Does a 2005 Honda Fit/Jazz have a replaceable transmission filter?
No. The manual has no filter, and the CVT uses an internal strainer and magnets. Routine service is fluid drain‑and‑fill with the correct Honda CVT fluid.

How often should the CVT fluid be changed on a 2005 Fit/Jazz?
A practical AU/NZ guideline is every 40,000–60,000 km or 2–3 years, sooner in heavy city use, hot climates, or with towing. Always use the Honda‑specified CVT fluid for the GD model.

Can an aftermarket inline filter be added to the CVT?
It’s not recommended. Extra restriction can upset CVT line pressure and flow, and may create new problems. Stick with regular fluid service and the factory design.
