Additional Notes

  • Across all configurations of the Mercedes-Benz GL-Class X164 covered here, the automatic transmission fluid capacity is uniformly 9 liters, applying to both the GL 450 4MATIC (164.871) and the GL 550 4MATIC (164.886).
  • The GL 450 4MATIC entries for 2006-2007 list a 9-liter capacity without the dry fill designation, while the 2007-2009 and later entries carry an explicit dry fill label, indicating the figure represents a complete fill from an empty transmission rather than a partial service top-up.
  • A dry fill capacity of 9 liters is a relatively large volume for a passenger vehicle automatic transmission, reflecting the size and complexity of the multi-speed unit used in a full-size SUV platform.
  • All intervals across every row are classified under normal use conditions, meaning none of the listed specifications carry a severe-use or first-change-only interval distinction.
  • For the GL 450 4MATIC 164.871 covering 2009-2012, the specifications split into two separate entries based on production number: units from production number 2834527 onward carry equipment code a89, while units up to production number 2834526 do not, though both retain the same 9-liter dry fill capacity.
  • The same production number boundary of 2834527 and the associated code a89 distinction also applies to the GL 550 4MATIC 164.886 for the 2009-2012 period, with both variants again sharing the 9-liter dry fill figure.
  • The use of a production number cutoff rather than a model year boundary for the 2009-2012 GL 450 and GL 550 entries indicates a mid-cycle engineering change that does not alter the fluid volume requirement but does differentiate the transmission configuration for service identification purposes.
