Additional Notes

  • Across all four configurations of the Genesis G80 RG3 (USA), the automatic transmission fluid capacity is listed at 9.2 liters, a figure that reflects a full service fill rather than a partial drain-and-refill, which typically yields a lower recovered volume due to fluid retained in the torque converter.
  • The 60,000-mile change interval applies specifically under severe use conditions, meaning the interval is tied to more demanding operating circumstances rather than standard everyday driving cycles.
  • Both the 2.5 T-GDI and 3.5 T-GDI engine variants share an identical 9.2-liter transmission fluid capacity, indicating no variation in transmission fill volume between the turbocharged four-cylinder and turbocharged six-cylinder configurations.
  • The rear-wheel-drive and all-wheel-drive versions of each engine variant carry the same 9.2-liter automatic transmission fluid capacity, meaning the addition of AWD hardware does not alter the transmission's fluid fill specification.
  • All four configurations share a uniform 60,000-mile severe-use service interval, with no differentiation in change frequency between the 2.5 T-GDI, 2.5 T-GDI AWD, 3.5 T-GDI, and 3.5 T-GDI AWD variants.
