BYD L3

Manual transmission fluid capacity & service interval

BYD L3 manual transmission fluid capacity ranges from 1,6 to 2,1 liters. Service intervals include checks at 3000 km and 10000 km/6 months, and changes at 8000 km/3 months and 20000 km/12 months. The data covers 6 configurations.

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

Additional Notes

  • The BYD L3 manual transaxle fluid capacity differs between the two 1.5-liter engine variants. The 79 kW QCJ7153A unit carries a capacity range of 1.6–2.1 liters, while the 80 kW QCJ7153A5/A6/A7 and BYD7153A/A1 units carry a fixed capacity of 2.1 liters.
  • A capacity expressed as a range, such as the 1.6–2.1 liters listed for the 79 kW variant, typically reflects the difference between a drain-and-refill service fill and the full system volume, meaning actual fill quantity depends on how completely the transaxle was drained.
  • The fixed 2.1-liter capacity on the 80 kW variants represents a single specified fill volume, leaving no range for variation during a standard fluid service.
  • Both engine variants share an identical first-change-only interval of 8000 km or 3 months. A first-change-only interval is applied once after initial break-in, when metal particles and manufacturing residues are most likely to have accumulated in the fluid.
  • Following the first change, subsequent fluid changes for both variants are scheduled at 20000 km or 12 months, whichever comes first, representing a notably longer interval than the break-in service.
  • A fluid level check interval of 10000 km or 6 months applies to both variants under subsequent use conditions, running on a separate schedule from the full fluid change interval.
  • Under normal use conditions, both variants also specify an initial inspection check at 3000 km, which falls well before the first-change interval of 8000 km and serves as an early verification of fluid level and condition.
