Additional Notes

  • Across all four configurations in the Mercedes-Benz C-Class W206/S206/V206 lineup, the automatic transmission dry fill capacity is rated at 10 liters. A dry fill figure represents the total fluid volume required when filling a completely drained or newly assembled transmission, as opposed to a partial service fill where residual fluid remains in the torque converter and cooler lines.
  • The C 300 (206.046/246) and C 300 4MATIC (206.047/247), both introduced from 2021, share an identical 10-liter dry fill capacity and a 77,500-mile change interval under normal use conditions.
  • The C 43 AMG 4MATIC (206.087/287), introduced from 2022, carries the same 10-liter dry fill capacity and 77,500-mile normal-use change interval as the C 300 variants, despite representing a higher-output AMG configuration.
  • The C 63 AMG S E Performance (206.080/280), introduced from 2023, also specifies a 10-liter dry fill and a 77,500-mile change interval under normal use conditions, consistent with the rest of the W206 range covered here.
  • The 77,500-mile change interval applies specifically to normal use conditions across all listed configurations. Normal use, in transmission service contexts, generally refers to standard on-road driving without sustained high loads, frequent towing, or extreme temperature exposure.
  • No service fill capacity distinct from the dry fill figure is listed for any of the four configurations, meaning the specifications do not separate a partial drain-and-fill volume from the full overhaul volume within the provided data.
