Hongqi H9
Automatic transmission fluid capacity & service interval
Specifications cover Hongqi H9 automatic transmission fluid with capacities of 6.5 liters and 8.5 liters (dry fill). Four configurations of the model are included in the data.

Additional Notes
- The Hongqi H9 automatic transmission fluid capacity splits into two distinct values: 6.5 liters for a service fill and 8.5 liters for a dry fill, the latter representing the total volume required when filling a completely drained or rebuilt unit with no residual fluid remaining.
- The 2.0 liter difference between the service fill and dry fill figures across all H9 configurations reflects the volume of fluid that typically remains trapped in the torque converter and transmission passages during a standard drain, making the 6.5-liter figure the practical refill amount in most service scenarios.
- The 2.0T, 2.5T, and 3.0T variants of the H9 share identical automatic transmission fluid capacities of 6.5 liters (service) and 8.5 liters (dry fill), indicating no variation in transmission fluid volume requirements across the three engine displacements available from 2024 onward.
- The H9+ 3.0T uses a semi-automatic dual-clutch transmission (DCT) rather than a conventional automatic, yet carries the same 6.5-liter service fill and 8.5-liter dry fill capacities as the fully automatic units in the standard H9 lineup.
- All four configurations listed carry a normal use condition designation, meaning the stated capacities and any associated service parameters apply to standard operating conditions rather than severe or heavy-duty use cycles.
