Additional Notes

  • The Mercedes-AMG GT C192 automatic transmission fluid capacity is specified as a range of 10 to 11 liters, which reflects a service fill figure rather than a total system or overhaul capacity. A range rather than a fixed value accounts for fluid retained in the torque converter and passages during a drain-and-fill procedure.
  • Both the GT 55 AMG 4MATIC+ (192.380) and the GT 63 AMG 4MATIC+ (192.378) share the same 10-11 liter capacity specification, indicating no variation in transmission fluid volume between the two engine configurations for the 2023 model year.
  • The change interval for both configurations is 37,500 miles or 36 months, whichever comes first, under normal use conditions. The 36-month time limit means a fluid change is due regardless of mileage if three years elapse before the distance threshold is reached.
  • A 37,500-mile automatic transmission fluid interval is relatively short by modern standards, where many manufacturers specify intervals of 60,000 miles or longer. The normal use designation here applies to both the 192.380 and 192.378 without a separate severe-use interval listed in the specifications.
