The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
  • Yuan 1.5T (2016-2019)
  • DCT
  • Use: Normal
  • Capacity 1,8 liter
  • Change 60000 km
  • Code: 6DT25 6/1

Additional Notes

  • The BYD Yuan 1.5T carries an automatic transmission fluid capacity of 1.8 liters, a figure consistent with a service fill in a compact dual-clutch transaxle rather than a full overhaul quantity, which would typically be higher due to torque converter volume in conventional automatics.
  • The 1.5T unit is noted as a semi-automatic DCT transaxle, meaning the gearbox combines a dual-clutch mechanism with an integrated differential and final drive assembly, all sharing the same fluid volume of 1.8 liters.
  • The 60,000 km change interval applies under normal use conditions for the 2016-2019 Yuan 1.5T, placing the service frequency in a range commonly associated with moderate driving without sustained high-load or high-temperature operation.
