Hummer H2 SUT (USA / CAN)

Automatic transmission fluid capacity & service interval

Hummer H2 SUT (USA / CAN) requires automatic transmission fluid with a capacity range of 4,7 to 5,7 liters. Service intervals include changes at 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 SUT 6.0 V8 (2003-2007) carries an automatic transmission fluid capacity of 4.7 liters, which represents a service fill volume typical of a partial drain-and-refill procedure rather than a full overhaul capacity.
  • Moving to the 6.2 V8 configuration (2007-2010), the automatic transmission fluid capacity rises to 5.7 liters, a full liter more than the 6.0 V8 — a difference that reflects the larger transmission unit paired with the higher-displacement engine.
  • The 6.2 V8 Flex-power variant (2008-2010) shares the same 5.7-liter automatic transmission fluid capacity as the standard 6.2 V8, indicating no capacity difference between the conventional and flex-fuel versions of that engine.
  • Under normal use conditions, all three configurations specify a 160,000 km automatic transmission fluid change interval, which is a relatively extended drain cycle consistent with modern long-life fluid formulations.
  • Under severe use conditions, the change interval for all three configurations is halved to 80,000 km. Severe use typically encompasses operating conditions such as frequent towing, trailer hauling, or sustained low-speed high-load driving that accelerates fluid degradation.
  • The 6.0 V8 and 6.2 V8 configurations share identical service intervals — 160,000 km for normal use and 80,000 km for severe use — despite the difference in fluid capacity between the two engine families.
