Additional Notes

  • The GMC Envoy automatic transmission fluid capacity is 4.7 liters across all listed configurations, spanning both the 4.2 24V inline-six and the 5.3 V8 engine variants from 2001-2009. A 4.7-liter figure typically represents a service fill rather than a full overhaul or dry fill capacity, meaning the value reflects the amount of fluid exchanged during a standard drain-and-refill procedure.
  • All configurations share a 12-month check interval regardless of engine type, model year group, or use condition. A periodic check interval separate from the change interval indicates that fluid level and condition are monitored on a recurring annual basis between full service events.
  • Under normal use conditions, the change interval for automatic transmission fluid is 100,000 miles across every listed configuration, covering both the 4.2 24V and 5.3 V8 engines in both the 2001-2005 and 2006-2009 model year groups.
  • Under severe use conditions, the change interval is reduced to 50,000 miles across all configurations. Severe use conditions generally refer to operating environments that place greater thermal and mechanical stress on transmission fluid, such as frequent towing, stop-and-go driving, or extreme temperatures, which accelerate fluid degradation relative to normal use.
  • The severe-use change interval of 50,000 miles represents exactly half the 100,000-mile normal-use interval, a relationship that holds consistently across all eight listed specification rows without variation by engine or model year group.
  • The 5.3 V8 engine variant first appears in the specifications beginning with the 2003 model year, while the 4.2 24V configurations are listed from 2001. Despite the difference in displacement and cylinder count, both engines share identical transmission fluid capacity and service interval values throughout their respective listed ranges.
  • The transition from the 2001-2005 model year group to the 2006-2009 group produces no change in any transmission fluid specification for either engine variant. Capacity remains at 4.7 liters, the check interval remains at 12 months, and both the normal and severe change intervals remain at 100,000 and 50,000 miles respectively.
