Additional Notes

  • The Kia Forte YDm 1.6 T-GDI carries a transaxle fluid capacity of 1.9–2 liters for its semi-automatic unit, a notably small volume that reflects the compact internal design of a dual-clutch or automated manual-style transaxle rather than a conventional torque-converter automatic.
  • The 2.0 GDI and 2.0 MPI variants use a conventional automatic transaxle with a fluid capacity of 6.7 liters, a figure more than three times that of the 1.6 T-GDI semi-automatic, consistent with the larger sump and torque converter volume found in traditional step-gear automatics.
  • Across the 1.6 T-GDI configurations covering 2016-2018, a fluid check interval of 37,500 miles or 30 months applies under both normal and severe use conditions, meaning the inspection schedule remains constant regardless of driving environment.
  • Under severe use conditions, the 1.6 T-GDI semi-automatic transaxle carries a fluid change interval of 75,000 miles. No fluid change interval is listed for normal use, indicating that under normal conditions a periodic check rather than a scheduled replacement is specified.
  • The 2.0 GDI and 2.0 MPI automatic transaxles share an identical 60,000-mile fluid change interval under severe use conditions across both the 2016-2017 and 2017-2018 model year groupings, with no change interval listed for normal use.
  • The 1.6 T-GDI specifications appear under two overlapping model year groupings, 2016-2017 and 2017-2018, with identical capacity and interval values in each. The 2017 model year is therefore covered by both groupings simultaneously.
  • The same overlap pattern applies to the 2.0 GDI and 2.0 MPI engines, where 2016-2017 and 2017-2018 groupings carry identical 6.7-liter capacity figures and 60,000-mile severe-use change intervals, with 2017 appearing in both ranges.
  • The 2.0 GDI and 2.0 MPI engines share the same automatic transaxle fluid capacity of 6.7 liters and the same service intervals across all listed configurations, reflecting the use of a common transmission unit despite differing fuel delivery systems between the two engines.
