Parts for your 2008 Honda Cr-v-Transmission filter

2008 Honda CR‑V transmission filter: what owners should know

For the 2008 Honda CR‑V with the 5‑speed automatic, there isn’t a conventional, serviceable transmission filter to replace. Honda’s factory documentation for the 2007–2011 CR‑V generation specifies an internal strainer built into the transmission assembly, not an external filter. The Honda Electronic Parts Catalogue for this model also doesn’t list a replaceable ATF filter, and the Honda CR‑V Service Manual (Automatic Transmission section) describes the strainer as an internal component only accessed during an overhaul.

Because the filter isn’t a routine service item, transmission care on this model focuses on using the correct fluid and changing it at sensible intervals. Honda engineered these boxes with an internal mesh strainer and a magnetic drain plug to trap debris, so periodic fluid changes do the heavy lifting in terms of longevity. The owner’s manual and Service Manual call for Honda ATF DW‑1, and many vehicles will prompt for fluid service via the Maintenance Minder. In local conditions, plenty of workshops advise changing the ATF around 60,000–100,000 km, or sooner if the vehicle tows, sees hot climates, or lots of stop‑start driving.

On a drain‑and‑fill, expect roughly 3–3.5 litres to come out (not the full capacity), so some technicians like to do two or three drain‑and‑fills with short drives between to refresh more of the fluid without using a power flush machine. Avoid universal fluids and aggressive flushing, these transmissions respond best to genuine Honda DW‑1 and gentle service methods.

• No serviceable transmission filter: internal strainer only (overhaul access).
• Fluid: Honda ATF DW‑1 (don’t mix with non‑approved fluids).
• Method: drain‑and‑fill via the drain plug, consider repeating to increase renewal percentage.
• Interval: follow the Maintenance Minder, many workshops suggest 60,000–100,000 km depending on use.

FAQs

Does the 2008 Honda CR‑V have a replaceable transmission filter?
Not as a routine service item. It uses an internal strainer inside the transmission case, intended to be accessed only during a rebuild. Regular maintenance is centred on changing the ATF with Honda DW‑1.

How often should the transmission fluid be changed on a 2008 CR‑V?
Follow the Maintenance Minder where fitted. In Aussie and NZ conditions, many workshops recommend every 60,000–100,000 km, or sooner for towing, hot climates, or heavy city use. Always use Honda ATF DW‑1.

Should a flush machine be used on this transmission?
It’s generally better to do one to three gentle drain‑and‑fills rather than a power flush. This approach refreshes the fluid without shocking the system and aligns with Honda’s recommended service style.
