Hummer H3 (USA / CAN)

Automatic transmission fluid capacity & service interval

Hummer H3 (USA / CAN) uses automatic transmission fluid with a capacity of 4,7 liters. Service intervals include 80000 km/ 24 months, 160000 km, and 80000 km. The data covers 4 configurations.

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

Additional Notes

  • Across all engine configurations in the Hummer H3 (USA / CAN) lineup, the automatic transmission service fill capacity is 4.7 liters, meaning the figure applies to a drain-and-refill service rather than a complete overhaul, which would require a higher total volume to account for fluid retained in the torque converter and passages.
  • The 3.5-liter engine, covering model years 2005-2007, carries a service interval of 80,000 km or 24 months under normal use conditions, whichever comes first.
  • The 3.7-liter engine, introduced for 2007 and continuing through 2010, shares the same 4.7-liter service fill capacity and the same 80,000 km / 24-month normal-use interval as the earlier 3.5-liter variant.
  • The 5.3 V8, available from 2008-2010, has a notably longer normal-use service interval of 160,000 km, which is double the interval specified for both four-cylinder configurations.
  • Under severe use conditions, the 5.3 V8 interval drops to 80,000 km, aligning with the four-cylinder normal-use interval and reflecting the additional thermal and mechanical stress associated with demanding operating conditions.
  • The 5.3 V8 is the only configuration in the H3 lineup for which a separate severe-use interval is specified, with the 80,000 km severe interval carrying no time-based component, unlike the 24-month qualifier attached to the four-cylinder normal-use schedule.
