Mercedes-Benz G-Class, W463B (EU)

Additional Notes

• The dry fill capacity across all four W463B configurations — G 350 d, G 400 d, G 500, and G 63 AMG — is listed at 10-11 liters. A dry fill figure represents the total fluid volume required when filling a completely drained or newly assembled transmission, as opposed to a service fill, which accounts for residual fluid remaining after a drain.
• The 1-liter spread in the dry fill capacity (10-11 liters) is a standard tolerance range, reflecting minor variation that can occur depending on how thoroughly the unit is drained and whether the torque converter is emptied during the procedure.
• All four variants share an identical fluid change interval of 120,000 km under normal use conditions. Normal use, in this context, refers to everyday driving patterns that fall outside of severe or demanding operating environments.
• The Mercedes-Benz G-Class W463B applies the same 120,000 km interval and 10-11 liter dry fill specification uniformly across both diesel variants (G 350 d and G 400 d) and petrol variants (G 500 and G 63 AMG), indicating no differentiation in automatic transmission fluid service requirements between the two fuel types in the 2019-2024 model range.
• The G 63 AMG (463.277) carries the same 10-11 liter dry fill capacity as the non-AMG variants despite housing a higher-output engine, suggesting the transmission unit itself is dimensionally consistent across the lineup rather than being a larger-capacity AMG-specific unit.
