Additional Notes

  • The Honda Odyssey RL6 3.5 V6 automatic transaxle carries a service fill capacity of 3.3 liters, which represents the amount of fluid exchanged during a routine drain-and-fill procedure rather than a full system overhaul.
  • A separate capacity figure of 4.3-4.5 liters is listed for the flexible on-board maintenance system interval, indicating a larger fill volume that accounts for a more thorough fluid exchange or total system capacity when the transaxle is fully drained including the torque converter.
  • Under severe use conditions, the automatic transaxle fluid change interval is set at 30,000 miles or 24 months, paired with the 3.3-liter service fill capacity.
  • A distinct interval applies specifically to the first change under severe use conditions, extending to 60,000 miles or 36 months, also with a 3.3-liter capacity. The "first change only" designation means the 60,000-mile or 36-month interval governs only the initial fluid service, after which the standard severe-use schedule of 30,000 miles or 24 months takes over.
  • The flexible on-board maintenance system interval does not carry a fixed mileage or time figure in the specifications, as the vehicle's onboard system determines when service is due based on operating conditions rather than a preset schedule.
