Additional Notes

  • The Hyundai Sonata NF (USA) automatic transaxle fluid capacity differs between the 2.4-liter and 3.3-liter engines, with the 2.4 ranging from 7.8 to 9.5 liters depending on model year, while the 3.3 holds 10.9 liters across all listed years.
  • The 2.4-liter engine in the 2006-2008 model years carries a transaxle fluid capacity of 7.8 liters, which is a total system fill figure representing the full volume of fluid the transaxle holds including the torque converter.
  • For the 2.4-liter engine in 2009-2010, the transaxle capacity increases to 9.5 liters, a notable jump of 1.7 liters over the earlier 2006-2008 specification for the same engine displacement.
  • The 3.3-liter engine carries a 10.9-liter transaxle fluid capacity across all listed years from 2006-2010, making no distinction between the 2006-only entry and the subsequent 2007-2008 and 2009-2010 groupings in terms of fluid volume.
  • Under normal use conditions, all configurations share an identical check interval of every 15,000 miles or 12 months, whichever comes first, alongside a change interval of 105,000 miles or 84 months.
  • The 84-month time limit on the normal-use change interval works out to seven years, meaning time elapsed can trigger a fluid change before the mileage threshold is reached in lower-mileage driving situations.
  • Under severe use conditions, all configurations across both engine types and all listed model years specify a fluid change interval of 30,000 miles, with no time-based interval listed alongside the mileage figure.
  • The severe-use change interval of 30,000 miles represents roughly 28.6% of the 105,000-mile normal-use change interval, reflecting the substantially greater stress placed on automatic transmission fluid under demanding operating conditions.
