Hummer H3T (USA / CAN)

Automatic transmission fluid capacity & service interval

Hummer H3T (USA / CAN) requires automatic transmission fluid with a capacity of 4,7 liters. Service intervals occur every 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 (Service fill)
  • Change 80000 km/ 24 months
  • Code: 4L60-E 4/1
H3T 5.3 V8 (2008-2010)
  • Use: Normal
  • Capacity 4,7 liter (Service fill)
  • Change 80000 km/ 24 months
  • Code: 4L60-E 4/1

Additional Notes

  • The Hummer H3T automatic transmission service fill capacity is 4.7 liters across both available engine configurations for 2008-2010.
  • A service fill capacity reflects the amount of fluid needed when servicing the transmission without a full disassembly, typically involving a pan drop and filter replacement rather than a complete overhaul.
  • The 3.7-liter inline-five and the 5.3 V8 share an identical 4.7-liter service fill capacity, indicating both engine variants use the same automatic transmission fluid volume for routine service.
  • The specified change interval for both configurations is 80,000 km or 24 months, whichever comes first, under normal use conditions.
  • Normal use conditions, as tied to the 80,000 km / 24-month interval here, generally represent standard driving patterns without the added stress of towing, off-road operation, or extreme temperatures.
  • The 24-month time-based interval means a fluid change is due after two years of operation even if the 80,000 km mileage threshold has not been reached.
