What is Honda ATF DW-1?
Honda ATF DW-1 is the official automatic transmission fluid specification endorsed by Honda for most of its automatic transmissions.

Who makes Honda transmission fluid DW-1?
Honda’s own line is marketed as Honda Genuine ATF DW-1.

What matters to consumers is that the product meets Honda’s DW-1 specification and is labeled accordingly.
- Honda Genuine ATF DW-1 is the official fluid for Honda and Acura automatic transmissions.
- The actual manufacturing of DW-1 fluid is handled by contract suppliers chosen by Honda; specific supplier names are not always disclosed publicly.
- Some third-party brands sell fluids marketed as meeting the DW-1 specification. These should only be used if they explicitly state compatibility with Honda DW-1 and are recognized as meeting Honda’s standard.
Before listing the key points, note that DW-1 is a specification, not a single company name. Here are the core takeaways:
In short, use Honda Genuine ATF DW-1 or a vetted third-party fluid that is clearly labeled as meeting the DW-1 specification and approved for Honda transmissions.
Choosing the right fluid and where to buy
To ensure proper performance and avoid compatibility issues, follow these guidelines when selecting transmission fluid for your Honda or Acura:
- Check your owner’s manual for the recommended specification (DW-1 for most Honda/Acura automatics).
- Look for fluids labeled either Honda Genuine ATF DW-1 or third-party fluids explicitly stating that they meet the DW-1 specification.
- Verify the product data sheet or label to confirm DW-1 compliance and suitability for your vehicle model year.
- Purchase from reputable retailers or authorized dealers to avoid counterfeit or mislabeled products.
Following these steps helps ensure you’re using the correct fluid and protecting your transmission over the long term.
Common questions about compatibility
Is Dexron VI or Mercon acceptable for Honda transmissions that require DW-1? In general, no. Honda specifies DW-1 for its automatic transmissions, and using Dexron VI or Mercon is not recommended unless a dealer or service bulletin explicitly approves it for a particular model and year. Always prioritize the DW-1 specification to maintain shifting quality and avoid potential warranty issues.
Where can I buy Honda ATF DW-1? You can purchase Honda Genuine ATF DW-1 at Honda dealerships, some automotive parts stores, and reputable online retailers. When buying third-party fluids that claim DW-1 compatibility, ensure the product is clearly labeled with DW-1 provision and is from a trusted brand or supplier.
Summary
Honda’s transmission fluid brand is Honda Genuine ATF DW-1, the official specification for most Honda and Acura automatics. The fluid is produced under contract by manufacturers selected by Honda, though exact suppliers are not publicly disclosed. While third-party fluids may claim DW-1 compatibility, the safest choice is Honda Genuine ATF DW-1 or a clearly labeled DW-1 fluid from a reputable source. Always consult your manual and follow proper maintenance intervals to keep your transmission operating smoothly.
