Additional Notes
- The Hongqi LS7/Guoyao transfer case fluid capacity of 1.15 liters applies to both the LS7 4.0T and the Guoyao 4.0T under normal use conditions.
- A transfer case fill volume of 1.15 liters is characteristic of a compact transfer unit, consistent with the relatively small fluid volumes typical of modern electronically controlled transfer cases in full-size SUV platforms.
- The LS7 4.0T covers model years 2022-2024, while the Guoyao 4.0T carries a starting year of 2024, yet both share the identical 1.15-liter transfer case capacity under normal use conditions.
- The capacity figure listed for both configurations represents a service fill level, meaning the volume of fluid required when refilling the transfer case during routine maintenance rather than a complete overhaul or dry-fill scenario.
- Both configurations are noted specifically as transferbox applications, distinguishing the transfer case fluid service from other drivetrain fluid services such as front or rear differential fills.
