Additional Notes
- The BYD Song Pro transaxle holds 2 liters of manual transmission fluid under normal use conditions, which is a typical service fill volume for a compact front-wheel-drive manual transaxle where the gearbox and differential share a common housing.
- The 2-liter capacity figure represents a service fill rather than an overhaul fill, meaning the measurement accounts for fluid retained in the transaxle during a standard drain-and-refill procedure rather than a fully dry assembly.
- Under normal use conditions, the manual transaxle fluid change interval is set at 40,000 km or 24 months, whichever comes first, reflecting a dual-trigger maintenance schedule based on both distance and elapsed time.
- The 24-month time-based interval runs alongside the 40,000 km distance trigger, which means a vehicle driven infrequently enough to avoid reaching the mileage threshold would still require a fluid change once two years have passed.
