Honda ATF DW-1 Automatic Transmission Fluid — 2-Quart OEM Bottle for Honda/Acura, Maintains Shift Quality

Genuine Honda 08200-9008 ATF DW-1 (ATF-Z1) is a factory-formulated automatic transmission fluid supplied in a 2-quart pack for Honda and Acura transmissions that require the DW-1/Z1 specification.

If you maintain a Honda or Acura vehicle that specifies ATF DW-1 (also referred to as ATF-Z1), using the exact OEM fluid helps ensure correct hydraulic performance, shift quality and torque-converter operation. This product is the genuine Honda item packaged in two-quart quantities for topping off or performing a fluid service without mixing with incompatible formulas.

Which vehicles and transmissions use Honda ATF DW-1?

This fluid is intended for Honda and Acura automatic transmissions and some power-steering systems that call specifically for the DW-1/ATF-Z1 specification. Always check your owner's manual or the transmission fill label to verify the required fluid type before adding or replacing fluid.

• OEM part number: 08200-9008 — factory-specified for compatible models
• Common in older Honda/Acura autos and some early-2000s models
• Also used in certain manual-hydraulic applications where DW-1 is listed

How does genuine Honda ATF DW-1 affect shift feel and transmission performance?

Honda-formulated ATF DW-1 is engineered to maintain the friction characteristics and hydraulic properties the transmission was designed for. Using the correct OEM fluid helps preserve gear engagement smoothness and consistent line pressures across temperature ranges.

• Maintains intended clutch friction for crisp, consistent shifts
• Stabilizes viscosity over typical operating temperatures
• Reduces the risk of shift delays caused by mismatched fluids

What practical steps should I follow when changing or topping off this fluid?

When servicing your transmission, drain and refill according to the vehicle manufacturer’s intervals and procedures. For topping off, add small increments and verify fluid level at the correct operating temperature and with the car level, following the factory checklist.

• Refer to the service manual for correct fill level and temperature procedure
• Use one product type—avoid mixing different ATF formulations
• Dispose of used fluid responsibly at an approved recycling center

How should I store unopened Honda ATF DW-1 and what is its shelf life?

Store the two-quart bottle in a cool, dry place away from direct sunlight and extreme temperature swings. Unopened OEM fluids typically retain usability for several years if kept sealed and protected from contamination.

• Keep the cap sealed and bottle upright to avoid leaks
• Avoid freezing or prolonged exposure to heat above recommended storage ranges
• Check the container for manufacturer date codes if extended storage is expected

Who is this for: This product suits DIY technicians, independent service shops and Honda/Acura owners who prefer factory-specified fluids. Choose the genuine 08200-9008 ATF DW-1 when the vehicle manufacturer explicitly lists DW-1/ATF-Z1 as the required fluid to maintain correct transmission operation and to prevent compatibility issues that can arise from aftermarket or mismatched fluids.
