In most modern Honda and Acura vehicles, Honda specifies Honda CVT Fluid Type H as the official transmission fluid for CVTs. Using this exact formulation helps ensure smooth operation and warranty coverage.
Honda's CVT fluid specification is published in owner's manuals and service bulletins. For most models, Type H is the recommended fluid; if a model has unique transmission software or a hybrid variant, verify the exact spec in the manual or with a dealer. Substituting a non-OEM CVT fluid can affect shifting performance and may affect warranty coverage.
What is Honda CVT Fluid Type H?
Honda CVT Fluid Type H is a synthetic CVT transmission fluid formulated to meet Honda's friction, viscosity, and heat-management requirements for its CVTs. It is designed to provide stable shifting, protection against wear, and effective temperature control under normal driving conditions. This fluid is what Honda specifies for most of its CVT-equipped vehicles, including many Civics, Accords, CR-Vs, and hybrids.
While there are other CVTF products on the market, Honda's official guidance centers on Type H for its current CVT lineup. If your vehicle's manual indicates a different specification due to a specific transmission code or market variant, follow that guidance.
Practical guidelines for use
Before listing the key points, note that Honda's official guidance emphasizes using the exact fluid specified in your manual. The following bullets summarize the typical expectations for most CVT-equipped Honda models.
- Avoid substituting with standard automatic transmission fluids or other CVT fluids unless explicitly approved for your model and year.
- Consult the owner's manual or dealer for model-year-specific requirements, as some variants may have unique specs.
- During a CVT fluid change, refill to the manufacturer's specified capacity and use a fluid that meets Type H requirements.
Use Honda CVT Fluid Type H as the default fluid for most Honda and Acura CVTs.
Following these guidelines helps maintain CVT performance and avoids warranty issues related to improper fluid use.
Model-specific considerations
Most Honda CVTs, including those in the Civic, CR-V, and many hybrids, are designed to operate with Honda CVT Fluid Type H. Acura models that use CVTs generally align with the same Type H specification, but service bulletins may note exceptions for particular transmissions or markets. Always confirm with the exact service bulletin or owner's manual for your VIN.
When in doubt, contact a Honda/Acura dealer or a certified shop to confirm the precise fluid specification for your vehicle's transmission code and model year.
Summary
Honda's standard CVT fluid for most modern CVTs is Honda CVT Fluid Type H. Use this fluid unless the owner's manual or a service bulletin specifies a different formulation for your vehicle's transmission. Always verify the exact requirement for your model year and VIN with official sources.
