Hummer H3T (USA / CAN)

Automatic transmission fluid capacity & service interval

Hummer H3T (USA / CAN) automatic transmission fluid capacity is 4,7 liters. Service intervals are 80000 km or 24 months. The data covers 2 configurations.

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

TypeSpecifications
H3T 3.7 (2008-2010)
  • Use: Normal
  • Capacity 4,7 liter
  • Change 80000 km/ 24 months
  • Code: 4L60-E 4/1
H3T 5.3 V8 (2008-2010)
  • Use: Normal
  • Capacity 4,7 liter
  • Change 80000 km/ 24 months
  • Code: 4L60-E 4/1

Additional Notes

  • Both the 3.7-liter inline-five and the 5.3 V8 share an identical automatic transmission fluid capacity of 4.7 liters, which represents a service fill figure rather than a full overhaul or dry-fill quantity.
  • A service fill capacity reflects the amount of fluid needed when draining and refilling without disassembling the transmission, meaning residual fluid remains in the torque converter and passages during a standard drain procedure.
  • The Hummer H3T carries a change interval of 80,000 km or 24 months under normal use conditions, whichever comes first, applying equally across both the 3.7 and 5.3 V8 engine configurations for the 2008-2010 model years.
  • The 24-month time-based threshold in the interval specification means a fluid change is due at two years of elapsed time even when the 80,000 km distance has not been reached, a common provision for vehicles that accumulate low annual mileage.
  • The alignment of capacity and interval figures across two mechanically distinct engines, a five-cylinder and a V8, points to the use of a shared automatic transmission unit in the H3T platform for the 2008-2010 period.
