Additional Notes

  • The GAC GS3 1.3T and 1.5 variants covering 2017-2022 share an identical automatic transaxle capacity of 6.7 liters, with no separate dry fill or service fill distinction listed, meaning the single figure applies to normal use conditions.
  • The GS3 EMZOOM 1.5T carries two distinct capacity values for its semi-automatic transaxle: a dry fill of 6.9 liters and a service fill of 5 liters. The dry fill represents the total fluid volume required when filling a completely empty or overhauled unit, while the service fill reflects the smaller volume needed when fluid is replaced during routine maintenance with residual fluid remaining in the system.
  • The 1.9-liter difference between the EMZOOM 1.5T dry fill and service fill figures indicates that nearly 1.9 liters of fluid is retained within the transaxle during a standard drain-and-fill service, a common characteristic of sealed or torque-converter-equipped units where full drainage is not achieved without disassembly.
  • Both output variants of the GS3 Power 1.5T, rated at 110 kW and 117 kW respectively, share the same automatic transaxle capacity of 6.6 liters under normal use conditions, despite differing in power output.
  • Each GS3 Power 1.5T variant is listed with two separate transaxle entries: one for the automatic unit at 6.6 liters and one for a semi-automatic DCT unit at 2 liters. A dual-clutch transmission typically holds less fluid than a conventional automatic, which aligns with the notably lower 2-liter figure recorded for the DCT transaxle.
  • The 2-liter DCT capacity across both GS3 Power 1.5T output variants is considerably lower than the automatic transaxle figures listed elsewhere in the specifications, reflecting the fundamentally different internal architecture of a dual-clutch unit compared to a traditional torque-converter automatic.
  • Across the full 2017-2022 model range, automatic transaxle capacities fall within a relatively narrow band of 6.6 to 6.9 liters for dry or single-figure fills, while the DCT service fill stands apart at 2 liters, representing the widest capacity variation across all listed configurations.
