Hummer H2 SUT (USA / CAN)

Transfer case fluid capacity & service interval

Hummer H2 SUT (USA / CAN) requires transfer case fluid with a capacity of 1,4 liters. Service intervals include checking every 12 months and changing at 80000 km or 83000 km. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Change 80000 km
H2 SUT 6.0 V8 (2003-2007)
  • Use: Normal
  • Capacity 1,4 liter
  • Check 12 months
  • Change 83000 km

Additional Notes

  • All three configurations of the Hummer H2 SUT share an identical transfer case fluid capacity of 1.4 liters, which is consistent with a service fill rather than a full overhaul quantity.
  • The 6.0 V8, covering model years 2003-2007, carries a fluid change interval of 83,000 km under normal use conditions.
  • Both the 6.2 V8 and the 6.2 V8 Flex-power configurations, spanning 2007-2010 and 2008-2010 respectively, share a slightly shorter change interval of 80,000 km under normal use conditions.
  • The 6.0 V8 specification includes a dedicated fluid check interval of every 12 months, a detail absent from the 6.2 V8 and 6.2 V8 Flex-power rows.
  • The 3,000 km difference in change intervals between the 6.0 V8 at 83,000 km and the two 6.2 V8 variants at 80,000 km represents a minor but distinct variation across engine generations.
  • The Flex-power designation on the 6.2 V8 variant, which refers to flex-fuel capability allowing operation on ethanol-blended fuels, does not alter the transfer case fluid capacity or change interval relative to the standard 6.2 V8.
