The 2020 Acura TLX V6 requires Honda/Acura ATF DW-1 transmission fluid. This specification applies to the TLX’s 9‑speed automatic transmission and should be used for any fluid changes.
The TLX V6 pairs a 3.5-liter V6 engine with a 9‑speed automatic transmission, and Acura’s service information specifies ATF DW‑1 as the correct fluid. Using fluids other than DW‑1 (or an approved equivalent) can affect shifting performance and transmission longevity. Always verify the exact specification in your owner's manual or with an Acura dealer, since some bulletins can update recommendations.
Fluid specification and compatibility
ATF DW‑1 is Acura’s designated transmission fluid for this transmission. It is formulated to provide the proper friction characteristics, heat resistance, and wear protection required by the 9‑speed automatic. When replacing fluid, use DW‑1 or a fluid that is explicitly rated to meet the DW‑1 specification. Do not substitute with older Dexron/Mercon fluids unless your manual explicitly approves it.
How to confirm the correct fluid for your vehicle
Check your owner's manual under the transmission section for the exact specification. Some TLX models may have a label on the transmission fill plug or related service info indicating ATF DW‑1. If you’re unsure, contact a certified Acura dealer or a qualified technician and reference your vehicle’s VIN to confirm current recommendations.
Maintenance considerations
Transmission fluid maintenance intervals vary by model year, driving conditions, and climate. Refer to the owner’s manual for the official service schedule. If you plan a DIY drain-and-fill, ensure you have the correct DW‑1 fluid and follow proper disposal guidelines for used fluid.
Bottom line
For a 2020 Acura TLX V6, use ATF DW‑1 (or an approved equivalent that meets the DW‑1 specification). This ensures proper shifting performance and transmission longevity. When in doubt, consult the owner’s manual or your local Acura service department.
Summary
The TLX V6 uses Honda/Acura ATF DW‑1 transmission fluid. Always verify with the owner’s manual and use DW‑1 or an approved equivalent to maintain optimal transmission performance.
