What kind of transmission fluid does a 2007 Honda Ridgeline take?
The 2007 Honda Ridgeline uses Honda ATF DW-1 automatic transmission fluid.
For owners, this means using the fluid specified by Honda to ensure smooth shifting, proper lubrication, and long-term reliability of the Ridgeline’s 5-speed automatic transmission. Below, we explain the DW-1 specification, why it matters, and practical maintenance guidance.
Transmission fluid specification
Understanding the DW-1 spec helps ensure you choose the right fluid and avoid issues that can arise from using non-Honda fluids in your transmission.
- Official specification for the Ridgeline’s 5‑speed automatic is Honda ATF DW-1 (also listed as ATF DW-1/DW1 in service literature).
- Avoid Dexron family fluids (Dexron II/III/VI) unless explicitly approved for your vehicle—using them can affect shifting and long‑term reliability.
- Many brands label and market “DW-1” or “DW-1 compatible” ATF; always verify the label and that it meets the DW-1 specification.
- Following Honda’s spec helps preserve warranty coverage and the transmission’s designed friction characteristics.
When in doubt, refer to your owner’s manual or contact a Honda dealer to confirm the exact fluid grade for your VIN, as there can be minor changes across production runs.
Maintenance and practical guidance
The following guidance covers checking level, topping up, and scheduling changes to keep the transmission performing well.
- Check the owner's manual for service intervals and whether your vehicle is equipped with a dipstick for transmission fluid level checks. If your Ridgeline has a dipstick, check with the engine running and in Park or Neutral, following the manual’s temperatures and procedures.
- Use the correct DW-1 fluid when topping up or replacing fluid; do not substitute with Dexron fluids.
- When performing a pan drain and fill, consider replacing the transmission filter if your service procedure calls for it.
- Store and handle ATF DW-1 properly; avoid contamination and store in a sealed container away from heat.
Regular adherence to the specified fluid and maintenance procedure helps maintain smooth engagement and shift quality over the vehicle’s lifespan.
Summary
For a 2007 Honda Ridgeline, the transmission fluid required is Honda ATF DW-1. Always use DW-1 labeled ATF, avoid Dexron-based fluids, and consult the owner's manual or a dealer for service intervals specific to your VIN. Proper fluid selection and routine maintenance support reliable shifting and long-term transmission health.
