Additional Notes

  • The Proton X90 1.5T, from 2023, carries an automatic transmission fluid capacity of 4 liters, which is consistent with a service fill volume for a dual-clutch transaxle unit rather than a full overhaul quantity.
  • The 4-liter figure applies specifically to the DCT transaxle configuration, meaning the fluid volume accounts for the dual-clutch assembly housed within the transaxle casing rather than a conventional torque converter arrangement.
  • The listed capacity is tied to normal use conditions, indicating the 4-liter service fill is the standard interval quantity under everyday driving circumstances.
