Additional Notes

  • The Hyundai Elantra GT, PD (USA) manual transaxle capacity is specified as 1.7–1.8 liters across all engine configurations in the 2017-2020 range, a figure typical of a service fill rather than a full overhaul drain, where residual fluid in passages and cooler lines is not fully recovered.
  • The 1.6 T-GDI and 2.0 GDI engines share the same 1.7–1.8 liter capacity range, meaning the manual transaxle fill volume does not differ between the turbocharged and naturally aspirated variants.
  • Under normal use conditions, neither the 1.6 T-GDI nor the 2.0 GDI specifies a fluid change interval, only a fluid level check, which means the service action at each scheduled interval is inspection rather than replacement.
  • The 1.6 T-GDI check interval under normal use is set at 24,000 miles or 48 months, while the 2.0 GDI check interval under the same condition is 30,000 miles at the same 48-month time limit, placing the turbocharged engine on a shorter mileage-based inspection schedule.
  • Under severe use conditions, the 1.6 T-GDI carries a fluid change interval of 72,000 miles, whereas the 2.0 GDI is assigned a 75,000-mile change interval, a difference of 3,000 miles between the two engine variants.
  • The severe use check intervals mirror the normal use intervals for each engine: 24,000 miles or 48 months for the 1.6 T-GDI and 30,000 miles or 48 months for the 2.0 GDI, with the fluid change requirement added on top of the existing check schedule.
  • The 1.6 T-GDI specifications appear across two overlapping year groupings, 2017-2018 and 2018-2020, with identical capacity and interval values in both, indicating no specification revision occurred between those groupings for the turbocharged engine.
  • The same pattern of overlapping year groupings with unchanged values applies to the 2.0 GDI, where the 2017-2018 and 2018-2020 entries carry identical capacity and interval figures across both normal and severe use conditions.
