Additional Notes

  • The Lexus LX 600 AWD transfer case holds 1.79 liters of fluid, a figure that applies to both the Canadian and U.S. market configurations.
  • The Canadian specification calls for a fluid check at 16,000 km or 12 months under normal use conditions, rather than a full fluid change.
  • The U.S. specification assigns a change interval of 30,000 miles or 36 months, and I note this interval is tied specifically to severe use conditions.
  • A check interval and a change interval represent meaningfully different service actions. The Canadian normal-use schedule requires only verifying fluid level and condition, while the U.S. severe-use schedule requires a complete fluid replacement.
  • The 36-month time limit on the U.S. change interval means the fluid is due for replacement at whichever threshold arrives first, whether the mileage or the calendar limit.
  • Both market rows carry the notation "transferbox," identifying the fluid capacity as specific to the transfer case assembly rather than a combined drivetrain fill figure.
