Mercedes-AMG GT 63 AMG 4MATIC+, 192.378 (2023- )
  • Use: Normal
  • Capacity 0,65-0,68 liter
  • Change 49500 miles/ 36 months

Additional Notes

  • The Mercedes-AMG GT C192 transfer case fluid capacity is specified as a range of 0.65 to 0.68 liter. A fill range rather than a single fixed value typically reflects the need to verify the correct level at the fill plug rather than relying on a measured pour alone.
  • Both the GT 55 AMG 4MATIC+ (192.380) and the GT 63 AMG 4MATIC+ (192.378) share an identical capacity range of 0.65 to 0.68 liter, indicating no variation in transfer case size between the two engine variants within the C192 platform.
  • The service interval for both configurations is 49,500 miles or 36 months under normal use conditions, meaning the time-based threshold of 36 months may trigger a fluid change before the mileage limit is reached in lower-mileage driving patterns.
  • A 36-month time interval alongside a 49,500-mile mileage interval reflects a dual-trigger service schedule, where whichever limit is reached first governs when the fluid change is due.
  • The 49,500-mile interval is a relatively extended drain interval for a transfer case, which is consistent with modern sealed or low-maintenance transfer unit designs that use long-life synthetic fluids.
