Additional Notes

  • The Toyota Avalon XX50 transfer case fluid capacity is 0.45 liter across all listed configurations, covering both the 2.5 hybrid AWD and the 3.5 V6 AWD variants. A capacity this small is characteristic of a compact transfer unit rather than a traditional four-wheel-drive transfer case.
  • Under normal use conditions, the 2.5 AWD (2020-2021) transfer case calls for an inspection interval of 15,000 miles or 18 months, whichever comes first, rather than a fluid change.
  • Under severe use conditions, the same 2.5 AWD (2020-2021) transfer case shifts from an inspection to an actual fluid change at the same 15,000-mile or 18-month interval. The mileage and time threshold stays identical, but the required service action differs based on operating conditions.
  • The 3.5 V6 AWD (USA) follows the same pattern as the 2.5 AWD: a fluid check at 15,000 miles or 18 months under normal conditions, and a full fluid change at the same interval under severe conditions.
  • The 3.5 V6 AWD (USA) appears across two overlapping year groupings in the specifications, one covering 2019-2021 and another covering 2021-2022, both sharing the identical 0.45-liter capacity and the same 15,000-mile or 18-month service intervals under both normal and severe conditions.
  • The 18-month time-based interval listed alongside the 15,000-mile mileage threshold means service is due when either limit is reached first, which is relevant for low-mileage vehicles that may not accumulate 15,000 miles within a year and a half.
