Additional Notes

  • The BYD Song 1.5T automatic transaxle holds 4.3 liters of fluid, a figure consistent with a service fill rather than a full overhaul capacity.
  • The semi-automatic DCT transaxle in the Song 1.5T carries a notably larger fluid capacity of 7.2 liters, which reflects the dual-clutch unit's additional hydraulic circuit and clutch pack lubrication demands compared to the conventional automatic transaxle.
  • A change interval of 60,000 km or 36 months is specified for the automatic transaxle under normal use conditions, pairing a distance-based and a time-based threshold so whichever is reached first governs the service point.
  • No change interval appears in the specifications for the 1.5T DCT transaxle, whereas the conventional automatic transaxle carries a defined 60,000 km or 36-month interval under normal use.
