Hyundai Sonata, Y3 (EU)

Automatic transmission fluid capacity & service interval

Hyundai Sonata, Y3 (EU) uses automatic transmission fluid with a capacity range of 5,8 to 7,5 liters. Service intervals occur every 30000 km or 24 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Hyundai Sonata Y3 (EU) automatic transaxle fluid capacity varies across engine variants, ranging from 5.8 liters in the 1.8i and 2.0i to 7.5 liters in the 3.0i V6, reflecting the greater fluid volume demands of a larger displacement engine paired with a more substantial transmission assembly.
  • The 1.8i and 2.0i variants share an identical automatic transaxle fluid capacity of 5.8 liters across the 1994-1998 model years, indicating both engines use the same transaxle unit or one with equivalent fluid volume requirements.
  • The 2.0i 16V carries a slightly higher capacity of 6.1 liters compared to the standard 2.0i at 5.8 liters, a difference of 0.3 liters that points to a distinct transaxle configuration associated with the higher-output 16-valve engine variant.
  • At 7.5 liters, the 3.0i V6 automatic transaxle holds nearly 1.4 liters more fluid than the 2.0i 16V and nearly 1.7 liters more than the base 2.0i, a gap consistent with the larger physical size of a V6-matched transaxle.
  • All four engine variants share the same service interval of 30,000 km or 24 months under normal use conditions, meaning the change frequency is uniform regardless of engine displacement or transaxle fluid capacity.
  • The 24-month time limit paired with the 30,000 km distance interval means a fluid change is due when either threshold is reached first, which is standard practice for time-and-distance service scheduling.
  • All capacity figures listed represent transaxle fill volumes, which in automatic transmission service typically account for the fluid held within the torque converter, valve body, and transmission case collectively rather than a partial drain-and-fill quantity.
