Additional Notes

  • The BYD Song Max, across both the 113 kW and 118 kW variants spanning 2018-2022, shares an identical automatic transmission fluid capacity of 7.2 liters, applying to the transaxle in each case.
  • A 7.2-liter fill is a relatively substantial capacity for a dual-clutch transaxle, which is consistent with a full-system service volume rather than a partial drain-and-fill figure.
  • Both the 113 kW and 118 kW configurations are noted as semi-automatic DCT (dual-clutch transmission) units, meaning the fluid serves both the clutch packs and the gear-set lubrication circuits within a single transaxle housing.
  • The capacity specification for both Song Max variants is listed under normal use conditions, meaning the 7.2-liter figure applies to standard operating environments rather than severe-duty cycles.
  • The 113 kW and 118 kW Song Max variants carry the same 7.2-liter transaxle capacity across the full 2018-2022 model year span, indicating no revision to the fluid volume requirement between those two power outputs.
