Additional Notes

  • The BAIC Senova BJ40 manual transaxle fluid capacity is 2.6 liters across all five power variants — 150 kW, 160 kW, 165 kW, 170 kW, and 184 kW — in the 2023 model year.
  • A transaxle is a combined unit housing the transmission and axle differential in a single assembly, and the 2.6-liter figure represents a service fill capacity rather than a full overhaul or dry-fill volume.
  • The fluid change interval is specified at 40,000 km or 24 months, whichever comes first, and applies under normal use conditions for all five power variants.
  • The dual-trigger interval structure — distance and time — means a vehicle covering low annual mileage would still require a fluid change at the 24-month mark under normal use conditions before reaching 40,000 km.
  • The uniform 2.6-liter capacity across the 150 kW through 184 kW variants indicates a shared transaxle housing design despite the spread of 34 kW between the lowest and highest output configurations.
  • The identical 40,000 km / 24-month change interval across all five power variants reflects a single service schedule applied regardless of output level under normal use conditions.
