Additional Notes
- The GMC Envoy (USA / CAN) transfer case holds 1.8 liters of fluid across all listed configurations, spanning the 4.2 24V inline-six and the 5.3 V8 engines.
- A 1.8-liter transfer case capacity is a relatively modest fill volume, consistent with the compact internal dimensions typical of part-time and active transfer cases used in mid-size SUV platforms.
- The 4.2 24V configuration carries the same 1.8-liter capacity across both the 2001-2005 and 2006-2009 model year groups, indicating no change in transfer case fluid volume between those two production periods.
- The 5.3 V8 configuration, available from 2003-2009, also shares the 1.8-liter capacity, meaning the engine displacement difference between the inline-six and V8 variants did not result in a different transfer case fluid requirement.
- Under normal use conditions, all four configurations specify a fluid check interval of 12 months, meaning the transfer case is to be inspected on an annual basis regardless of mileage accumulation.
- The fluid change interval for all listed configurations under normal use is 50,000 miles, a figure that applies uniformly across both engine types and both model year ranges covered in the specifications.
