Additional Notes

  • The Lexus GX 470 (UZJ120) transfer case holds 1.4 liters of fluid across all model years and markets covered in the specifications, indicating a consistent service fill capacity for the transferbox throughout the 2003-2009 production span.
  • For the Canadian-market GX 470 (UZJ120), the transfer case fluid change interval is set at 64,000 km under normal use conditions, applying equally to both the 2004-2005 and 2006-2009 model year groups.
  • The Canadian-market specifications also include a fluid level check interval of 16,000 km under normal use, which is separate from and more frequent than the 64,000 km change interval.
  • For the 2003 USA-market GX 470 (UZJ120), the normal use condition specifies a fluid check at 30,000 miles or 24 months, while severe use conditions call for a full fluid change at that same 30,000-mile or 24-month threshold.
  • The 2004-2005 USA-market UZJ120 extended the time-based component of the interval from 24 months to 36 months compared to the 2003 model year, while retaining the 30,000-mile mileage threshold for both normal and severe use conditions.
  • For the 2006-2009 USA-market GX 470 under severe use conditions, the transfer case fluid change interval is 15,000 miles or 18 months, which is half the distance and half the time of the severe-use change interval specified for the 2004-2005 model years.
  • The 2006-2009 USA-market normal use condition retains the 30,000-mile or 36-month check interval established for the 2004-2005 years, meaning the divergence between model year groups under USA specifications is confined to the severe use change schedule.
