Refilling with Fresh ATF

  1. Locate the Fill Hole/Dipstick Tube: For most Honda Accords, you will add new fluid through the transmission dipstick tube. Remove the dipstick.
  2. Insert Funnel: Place a long-neck funnel into the dipstick tube.
  3. Add New Fluid: Slowly pour the measured amount of new Honda ATF-DW1 fluid into the funnel. Add a little less than what you drained initially, as you’ll fine-tune the level shortly.
  4. Reinsert Dipstick: Remove the funnel and reinsert the transmission dipstick.

Checking Fluid Levels and Test Drive

  1. Lower Vehicle: Carefully raise the car off the jack stands, remove them, and lower the vehicle completely to the ground.
  2. Start Engine: Start the engine and let it run for a few minutes.
  3. Cycle Gears: With your foot on the brake, cycle the transmission through all gear selections (P, R, N, D, L/S) for a few seconds in each, then return to Park. This helps circulate the new fluid.
  4. Check Fluid Level (Warm): With the engine still running and warmed up, pull the dipstick, wipe it clean, reinsert it fully, and pull it out again. The fluid level should be between the “min” and “max” marks on the dipstick.
  5. Adjust as Needed: If the level is low, add small amounts of fluid (about 1/4 quart at a time), recheck, and repeat until the level is correct. Do not overfill.
  6. Test Drive: Take your Accord for a short, gentle test drive. Pay attention to how the transmission shifts. It should feel smoother and more responsive.
  7. Final Check: After the test drive, recheck the fluid level and inspect the drain plug area for any leaks.
