The 2000 Acura TL uses Honda/Acura ATF DW-1 automatic transmission fluid.
The TL from this era is equipped with a 4-speed automatic transmission, and Honda/Acura specifies ATF DW-1 for this unit. Do not substitute Dexron III, Mercon, or other non-DW-1 fluids, as using the wrong fluid can cause poor shifting or transmission damage. If DW-1 is unavailable locally, consult a dealer or look for a product explicitly labeled as DW-1-compatible and approved by Honda/Acura. Always verify with your owner's manual or service advisor for your specific VIN if you have any doubt.
Recommended fluid and how to shop
Before you buy, keep in mind the following guidelines to ensure you select the correct transmission fluid and avoid compatibility issues.
- Use Honda/Acura ATF DW-1 for the 4-speed automatic in the 2000 TL. This is the official specification for this transmission.
- Do not use Dexron III, Mercon, or other non-DW-1 formulations unless explicitly approved by Honda/Acura for this model year.
- Source options include Honda/Acura dealerships, automotive parts stores, and reputable online sellers that stock ATF DW-1 or DW-1-compatible fluids.
- For service, you may perform a drain-and-fill or a full transmission flush. If performing a drain-and-fill, plan for multiple quarts of fluid; a complete flush may require more. Always follow the service manual for the exact capacity and procedure.
Note: Fluid capacity and service intervals vary by vehicle, VIN, and transmission history. Always refer to the owner's manual or a certified technician for the precise specification, capacity, and maintenance interval for your car.
Notes on transmission options
The 2000 TL was offered with a 4-speed automatic transmission in most markets; there is no factory manual transmission option for this model year in the U.S. If your vehicle has a different transmission configuration due to a swap or unusual specification, always confirm the correct fluid with the new trans manufacturer or a dealer.
Summary
For a 2000 Acura TL, the correct transmission fluid is Honda/Acura ATF DW-1. Use DW-1 only, avoid Dexron/Mercon substitutions, and follow your owner's manual or a dealer’s guidance for service intervals and capacity. Regular, proper fluid maintenance helps maintain smooth shifting and long transmission life.
