Most Acura automatic transmissions currently use Honda/Acura ATF DW-1, while older models may require ATF Z1. For CVTs, Honda/Acura CVTF (HD/HCF-2 variants) is used. Always verify the exact specification in your owner’s manual or on the transmission dipstick.
Overview of Acura transmission fluids
Transmission fluid specifications in Acura vehicles vary by transmission type and model year. The most common fluids are DW-1 for traditional automatics and CVTF for continually variable transmissions. A smaller subset of models use transmissions sourced from other manufacturers and may require different fluids. The safest course is to follow the exact specification printed in the vehicle’s manual or on the transmission label.
Conventional automatic transmissions
The following fluids cover the typical needs of traditional automatic transmissions found in many Acura models. Use the grade specified by your model year.
- ATF DW-1 — Honda/Acura’s current standard for most modern automatic transmissions
- ATF Z1 — used in some older Honda/Acura automatic transmissions from earlier generations
Always confirm the exact specification for your vehicle, as using the wrong fluid can affect shifting performance and warranty coverage.
Continuously Variable Transmissions (CVTs)
CVTs in Acura vehicles rely on a dedicated CVT fluid. The current Honda/Acura CVTF specification is typically labeled HCF-2, and is designed for the unique needs of CVT systems.
- CVTF HCF-2 — the standard fluid for most Honda/Acura CVTs
If your vehicle uses a CVT but lists a different CVTF specification in the manual, follow that exact requirement. CVT fluids are not interchangeable with conventional ATF.
Special cases: ZF- and other manufacturer-supplied transmissions
Some Acura models may be equipped with transmissions supplied by other manufacturers (for example, ZF) that require their own branded fluids. These fluids are specified by the transmission supplier and the vehicle’s manual, and should not be substituted with DW-1 or CVTF unless explicitly approved by Acura.
- ZF Lifeguard fluids — used in certain ZF-based 8/9/10-speed transmissions; exact grade and compatibility depend on model/year
Always use the exact fluid grade and service interval recommended by the vehicle’s manufacturer. Using the wrong fluid can lead to shifting problems or transmission damage.
How to verify the correct fluid for your Acura
To ensure you’re using the right transmission fluid, follow these steps.
- Consult your owner’s manual for the exact ATF or CVTF specification and capacity.
- Check the transmission dipstick or service label under the hood or near the transmission for the recommended fluid type.
- Ask an Acura-certified technician or your dealer if you’re unsure about the transmission type and required fluid, especially after a transmission replacement.
- When performing a fluid change, use the specified grade exactly as listed; mixing fluids or using a substitute can cause shifting issues and warranty problems.
Note: If you have a transmission that isn’t clearly labeled or you’ve recently had maintenance, always recheck the latest manufacturer guidance or service bulletins for your specific model/year.
Summary
In most current Acura models, the standard automatic transmission fluid is ATF DW-1, while older automatics may require ATF Z1. CVTs use Honda/Acura CVTF such as HCF-2. A subset of models with non-Honda transmissions may require manufacturer-specific fluids (e.g., ZF Lifeguard fluids). Always verify the exact specification for your vehicle in the owner’s manual or with an Acura service professional to ensure optimal performance and warranty compliance.
What type of transmission fluid does Acura use?

What type of transmission fluid for Acura?
The type of transmission fluid you should use depends upon the make, model and year of your vehicle. For example, many General Motor cars will require a DEXRON fluid and Ford cars commonly specify a MERCON fluid. Always follow the vehicle manufacturer recommendation for proper fluid use and change interval.
Is 90,000 miles to late to change transmission fluid?
Most manufacturers recommend changing automatic transmission fluid every 30,000 to 60,000 miles. However, newer vehicles with synthetic fluids may last up to 100,000 miles under normal conditions.
Can low transmission fluid cause stuttering?
If shuddering occurs primarily between 30-45 mph, this suggests torque converter problems related to low fluid levels. This specific speed range often reveals transmission issues that might not be noticeable at other speeds.
