Additional Notes
- The Mercedes-Benz GL-Class X164 transfer case fluid capacity splits into two distinct values depending on the unit configuration: 0.5 liter for the standard transfer box and 1.5 liters when the dual range assembly is present.
- The 1.5-liter figure represents a threefold increase over the 0.5-liter standard capacity, reflecting the additional fluid volume required to lubricate the mechanical components of a dual range transfer case.
- Both the GL 450 4MATIC (164.871) and GL 550 4MATIC (164.886) share identical transfer case fluid capacities across all listed model year spans, with no variation between the two engine variants.
- The GL 450 4MATIC (164.871) carries transfer case fluid specifications across three consecutive production spans: 2006-2007, 2007-2009, and 2009-2012, each listing the same 0.5-liter and 1.5-liter dual range values.
- All transfer case fluid entries across the X164 lineup are designated for normal use conditions, with no separate severe-duty interval or capacity listed for any configuration.
- The GL 550 4MATIC (164.886) specifications begin with the 2007-2009 span, while the GL 450 4MATIC coverage starts from 2006, making the GL 450 the earlier-introduced variant within the X164 transfer case data.
