Additional Notes

  • The Honda Odyssey RL1 3.5 V6 automatic transaxle carries an overhaul capacity of 7.6 liters for 1999-2000 models across both USA and CAN markets. Overhaul capacity represents the total fluid volume required when the transmission is fully disassembled and refilled from dry, as opposed to a routine drain-and-fill procedure.
  • Service fill capacity for 1999-2000 models is 3.1 liters, which reflects only the volume displaced during a standard fluid drain. The gap between the 3.1-liter service fill and the 7.6-liter overhaul figure indicates that a significant portion of fluid remains in the torque converter and valve body during a routine service.
  • For 2001-2002 models, both overhaul and service fill capacities are expressed as ranges rather than fixed values — 7.6 to 8.3 liters for overhaul and 3.1 to 3.5 liters for service fill. This range applies equally to both the USA and CAN specifications for those years.
  • By 2003-2004, the overhaul capacity settles at a fixed 8.3 liters and the service fill at 3.3 liters for both markets, replacing the variable range seen in 2001-2002 units.
  • Canadian market specifications carry a single change interval of 30,000 miles or 24 months across all model years from 1999-2004, with no differentiation between use conditions.
  • USA market specifications distinguish between normal and severe use conditions for all model years covered. Under normal use, the change interval is 45,000 miles or 36 months, while severe use shortens that interval to 30,000 miles or 24 months — matching the single interval applied to all Canadian models.
  • The fluid check interval of 15,000 miles or 12 months is consistent across all configurations, model years, and both markets, regardless of use condition or regional specification.
  • The severe use change interval for USA models (30,000 miles / 24 months) is 15,000 miles and 12 months shorter than the normal use interval, representing a 33 percent reduction in the mileage threshold between drain cycles.
