GAC GS4
Manual transmission fluid capacity & service interval
The GAC GS4 manual transmission fluid capacity ranges from 2.2 to 2.7 liters depending on the fill type and configuration. Two configurations are covered in the data.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| GS4 1.5T (2024- ) |

| GS4 1.5T (2016- ) |

Additional Notes
- The GAC GS4 1.5T manual transaxle introduced from 2016 carries a dry fill capacity ranging from 2.5 to 2.7 liters, which reflects the total volume required when filling a completely drained or newly assembled unit.
- Service fill capacity for the same 2016 1.5T manual transaxle is 2.3 liters, a lower figure that accounts for residual fluid remaining in the unit during a standard drain and refill procedure.
- The gap between the dry fill range of 2.5-2.7 liters and the service fill of 2.3 liters on the 2016 1.5T transaxle is consistent with typical manual transmission servicing, where some fluid is retained in passages and the torque converter area even after draining.
- The 2024 1.5T manual transaxle carries a single listed capacity of 2.2 liters, which is lower than both the service fill and the dry fill values associated with the earlier 2016 variant, pointing to a revised or redesigned transaxle unit.
- Both configurations are specified under normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty or high-stress driving cycles.
