What kind of transmission fluid do Hondas take?
The short answer is: it depends on your Honda’s transmission type and model year. Most newer Hondas with automatic transmissions use ATF DW-1, CVTs require Honda CVT Fluid, and manual transmissions use Honda MTF or the GL-4 gear oil specified in the owner’s manual. Always verify the exact specification for your vehicle with the owner's manual or a Honda dealer.
Understanding Honda’s fluid requirements starts with the transmission type. Honda has several fluid families that apply to different drivetrain configurations, and using the wrong fluid can affect shifting behavior and long-term reliability. Below is a detailed look at current guidance, along with practical steps to confirm the right choice for your model.
Automatic transmissions
Most modern Honda automatic transmissions are designed to run on Honda’s own specification for automatic transmission fluid. There are historical variations, so it’s important to identify whether your car uses the newer DW-1 specification or an older Z1 specification, and to confirm compatibility with your specific model year.
Key points for automatics
In general, newer Honda automatics favor ATF DW-1. Older models that date from the late 1990s to the mid-2000s often used ATF-Z1. Do not mix fluid types, and do not substitute generic Dexron/Mercon fluids unless explicitly approved by Honda for your model. The exact specification can vary by transmission family (e.g., conventional automatics vs. newer 9- or 10-speed implementations), so checking the owner’s manual or a dealer bulletin for your VIN is essential.
Continuously Variable Transmissions (CVT)
Honda CVTs use a dedicated CVT fluid rather than traditional ATF. The recommended fluid type is specified by Honda for each CVT design, and it may be marketed simply as Honda CVT Fluid or by a code used in service literature. Using the exact Honda CVT fluid specified for your model year and CVT variant is important for maintaining smooth operation and preventing clutch or pulley wear.
What to use for CVTs
For most Honda CVTs, use Honda’s CVT fluid as specified in the owner’s manual. Do not substitute standard ATF or fluids labeled for non-CVT automatics, as CVT systems rely on different viscosity and friction characteristics. If your CVT is part of a hybrid or a newer platform, the fluid specification may be updated by Honda, so verify against the VIN and current service bulletin for your vehicle.
Manual transmissions
Manual transmissions in Hondas generally require a dedicated manual transmission fluid or gear oil rather than automatic transmission fluid. The exact specification—such as Honda MT-F or GL-4 75W-90 gear oil—depends on the model and year. Some Hondas use a dedicated MT-F (manual transmission fluid) from Honda, while others specify a GL-4 gear oil meeting certain viscosity standards. Always consult the owner’s manual for the correct product name and viscosity.
What to use for manuals
In practice, many recent Hondas use Honda MTF (manual transmission fluid), while some older or specific models call for a GL-4 75W-90 gear oil. Mixing fluids or using an unsuitable oil can lead to harder shifting or wear. If you’re unsure, reference the exact transmission code in your manual or contact a Honda service advisor for the precise specification for your VIN.
Practical tips for choosing and changing transmission fluid
Before you buy or replace transmission fluid, consider these guidance points to avoid common mistakes and ensure compatibility with your vehicle.
Always use the exact fluid type specified by Honda for your model and transmission. Fluid names and codes can vary by year and transmission family, even within the same model line.
Avoid mixing fluids from different families (for example, ATF DW-1 with ATF-Z1 or CVT fluid with ATF). If you’re unsure, err on the side of using a new fluid that matches the manual’s specification rather than attempting a partial flush with a substitute product.
When in doubt, consult your Honda dealer or a trusted service technician with access to VIN-specific service information. They can confirm the exact specification and advise on fluid change intervals based on operating conditions and climate.
What to do if you’re unsure about your vehicle
If you don’t have immediate access to your owner’s manual, use your vehicle identification number (VIN) to look up the exact fluid specification on Honda’s official site or call a dealership. Many newer Hondas also include a maintenance alert that can guide you to the correct fluid type. For hybrid or newer e-CVT designs, the fluid chemistry can differ from standard CVTs, so VIN-based confirmation is especially important.
Summary
Transmission fluid decisions for Hondas break down primarily by transmission type: automatic transmissions generally use ATF DW-1, CVTs require Honda CVT Fluid, and manual transmissions require Honda MT-F or a compatible GL-4 gear oil as specified. Always verify the exact specification for your vehicle in the owner’s manual or with a Honda service professional, and avoid mixing fluids. Proper fluid selection helps maintain smooth shifting and long-term transmission health.
