Most Acura models use DW-1 Automatic Transmission Fluid (ATF) for their automatic transmissions. Some CVT-equipped or hybrid configurations may require different fluids such as CVT fluid (commonly HCF-2). Always confirm the exact specification for your model and year by checking the owner's manual or consulting an Acura dealer.
Common fluids for Acura automatic transmissions
Here are the fluids most likely to apply to Acura automatics, depending on model year and transmission type.
- DW-1 Automatic Transmission Fluid (ATF DW-1): The standard fluid for most Acura automatics, including many J-series and newer transmissions. It is designed to support proper shifting, temperature control, and overall transmission longevity.
- OEM/Honda/Acura variants of DW-1: Some service kits or dealer-supplied fluids are DW-1 variants; using the exact OEM DW-1 is recommended when servicing at a dealer or independent shop.
Note: The exact fluid specification can vary by model and year; always check the owner's manual or a dealer for the precise specification.
CVT and alternative transmissions
ACURA's current mainstream lineup largely uses conventional automatics, but a few older or specialty configurations and hybrids may have different fluid requirements. For CVT-equipped Hondas and Acuras, the fluid specification is typically a Honda CVT fluid (often labeled HCF-2) or an equivalent as specified for the model, and DW-1 is not used in those CVTs.
- CVT fluid: Honda/Acura CVT Fluid (HCF-2) or equivalent as specified for your model
- Specialty transmissions or hybrids: Some hybrids may have unique fluid requirements per the service manual
Always verify the fluid type and change intervals in your owner's manual or with an Acura dealer, as misusing fluids can affect transmission performance and longevity.
How to verify the correct fluid for your Acura
Because model-year nuances matter, follow these steps to confirm the proper fluid:
- Check the owner's manual or the Maintenance Schedule booklet for the exact ATF specification (DW-1, HCF-2, etc.).
- Look up the exact transmission type for your VIN on Acura's official site or in the service manual.
- Consult your local Acura dealership or trusted independent shop if you're unsure.
Using the correct fluid is essential for performance and longevity; if you can't locate the manual, ask a dealer for the exact specification by model and year.
Summary
In short, Acura's most common transmission fluid for automatic transmissions is ATF DW-1. Some CVT or hybrid configurations may require CVT fluid such as HCF-2, or other specialty fluids. Always verify the exact specification for your model and year to ensure optimal shifting, protection, and warranty compliance.
