Additional Notes

  • The Reform Metrac 2003 and the Metrac 3003, S, and K variants from 1989-2000 share an identical transfer box capacity of 0.7 liter, placing them in the smallest capacity group across all listed configurations.
  • The Metrac 4004 and 4004 H from 1992-2000 both carry a transfer box capacity of 1.15 liters, a step up from the 0.7-liter figure of the earlier and lighter Metrac models in the same production era.
  • All 1989-2000 models follow a uniform service schedule: a fluid level check at 200 hours and a full fluid change at 600 hours or 24 months, whichever comes first. The 200-hour check interval reflects standard practice for monitoring fluid condition and level between full drain-and-fill services.
  • The H6 X and H7 X models from 2011-2013 reduce the check interval to 100 hours and the change interval to 300 hours or 24 months, a notably more frequent schedule than the 600-hour change interval applied to the 1989-2000 generation.
  • The 2011-2013 Metrac H6 X and H7 X both carry a 1.5-liter transfer box capacity, representing an increase over the 1.15-liter figure of the 4004-series models.
  • A first-change-only interval of 35 hours applies to the H6 X and H7 X from 2011-2013. An early fluid change at 35 hours is a break-in procedure intended to remove metal particles and contaminants generated during initial component wear-in, after which the standard 300-hour or 24-month schedule takes over.
  • The Metrac H7 X, 39D/1 and H8 X, 34D/7 configurations from 2016-2022 list a transfer box capacity range of 3.8-5.5 liters, a substantial increase over all earlier Metrac configurations. A capacity range rather than a fixed value typically reflects variation between dry-fill and service-fill quantities, or differences between sub-variants within the same model designation.
  • The 35-hour first-change-only interval carries over unchanged from the 2011-2013 H-series models to the 2016-2022 H7 X, 39D/1 and H8 X, 34D/7 configurations, even as the transfer box capacity increased significantly to the 3.8-5.5 liter range.
  • The 2016-2022 H7 X, 39D/1 and H8 X, 34D/7 share identical transfer box service specifications, including the 3.8-5.5 liter capacity, the 100-hour check interval, the 300-hour or 24-month change interval, and the 35-hour first change.
