Additional Notes

  • The Honda Power Carrier HP series transfer case fluid capacity is 2 liters across both the HP250 and HP400 configurations, representing a full service fill for the transferbox.
  • The HP250, covering serial numbers NA1-2000001 through 2599999, carries a transfer case fluid change interval of 300 hours or 12 months under normal use conditions, whichever comes first.
  • The HP400, covering serial numbers NAA-2000001 through 2799999, shares the same 300-hour or 12-month change interval under normal use conditions as the HP250.
  • The dual-format interval of 300 hours or 12 months means the service trigger is whichever threshold is reached first, accounting for both high-use and low-use operating patterns within a calendar year.
  • Despite differences in model designation and serial number ranges between the HP250 and HP400, the transferbox fluid capacity of 2 liters remains identical across both configurations.
