Hummer H2 (USA / CAN)

Automatic transmission fluid capacity & service interval

Hummer H2 (USA / CAN) requires automatic transmission fluid with a capacity range of 4,7 to 5,7 liters. Service intervals for fluid changes are 80000 km and 160000 km. The data covers 6 configurations.

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

Additional Notes

  • The Hummer H2 6.0 V8 (2002-2007) carries a 4.7-liter automatic transmission fluid capacity, which represents a service fill figure rather than a full overhaul or dry fill amount.
  • The 6.2 V8 and 6.2 V8 Flex-power configurations both hold 5.7 liters of automatic transmission fluid, a notably larger capacity than the 4.7 liters specified for the earlier 6.0 V8.
  • Across all six configurations, the normal-use service interval is set at 160,000 km, meaning fluid changes are expected at relatively extended mileage under standard operating conditions.
  • Under severe use conditions, the change interval for all configurations drops to 80,000 km, exactly half the normal-use figure, reflecting the increased thermal and mechanical stress placed on the fluid in demanding driving situations.
  • The 6.0 V8 covers model years 2002-2007, while the 6.2 V8 and 6.2 V8 Flex-power configurations begin with the 2007 and 2008 model years respectively, meaning 2007 represents a transition year between the two engine displacements.
  • The 6.2 V8 Flex-power variant, spanning 2008-2010, shares identical fluid capacity and service interval values with the standard 6.2 V8, indicating no transmission servicing differences between the two despite the Flex-power designation.
