Additional Notes

  • The Mercedes-Benz GLB-Class X247 automatic transmission fluid specifications cover a semi-automatic transaxle configuration across all listed variants, including the GLB 250, GLB 250 4MATIC, and GLB 35 AMG 4MATIC.
  • A semi-automatic transaxle combines the transmission and drive axle into a single housing, which is why the fluid capacity figure represents the entire integrated unit rather than a standalone gearbox.
  • Every listed variant carries a fluid capacity of 5.5 liters, meaning no configuration in the X247 lineup deviates from a uniform fill volume for the transaxle.
  • The 5.5-liter figure is a service fill capacity, reflecting the amount of fluid required during a standard drain-and-fill procedure rather than a full overhaul or complete disassembly of the unit.
  • All configurations specify a change interval of 77,500 miles under normal use conditions, placing the X247 in a long-drain service category by conventional standards.
  • The normal use condition tied to the 77,500-mile interval applies uniformly across the GLB 250 247.646, GLB 250 4MATIC 247.647, and GLB 35 AMG 4MATIC 247.651 variants.
  • The GLB 35 AMG 4MATIC 247.651 shares the same 5.5-liter capacity and 77,500-mile interval as the non-AMG variants, indicating no differentiation in transmission service requirements for the performance-oriented trim within the X247 range.
  • The GLB 250 247.646 and GLB 250 4MATIC 247.647 each appear under two separate year-range entries, with the 2019-2023 entries and the 2023-onward entries carrying identical capacity and interval values of 5.5 liters and 77,500 miles respectively.
