Additional Notes

  • Both the G 550 (463.261) and G 63 AMG (463.277) share an identical transfer case fluid capacity of 2.8 liters, which represents a service fill volume typical of a sealed transfer box rather than a full overhaul drain.
  • The Mercedes-Benz G-Class W463B carries a transfer case fluid change interval of 74,500 miles under normal use conditions, applying equally across the 2019-2024 model years for both available configurations.
  • The 74,500-mile interval is tied specifically to normal use conditions, meaning operating environments classified as severe may warrant a different service schedule outside what these specifications address.
  • The capacity figure of 2.8 liters is consistent across the G 550 and G 63 AMG despite the latter using a higher-output AMG-tuned powertrain, indicating both variants share the same transfer box unit for the 2019-2024 period.
