Additional Notes

  • The Toyota Highlander XU70 transfer case fluid capacity varies by engine, with the 2.4 AWD configuration holding 0.39 liter and the 3.5 V6 24V 4WD configuration holding 0.8 liter — a difference of more than double between the two drivetrains.
  • The 0.39-liter capacity of the 2.4 AWD transfer case is a relatively small fill volume, consistent with a compact, electronically controlled transfer unit rather than a traditional gear-driven transfer case assembly.
  • The 0.8-liter capacity on the 3.5 V6 24V 4WD reflects a larger transfer case unit, which typically requires a greater fluid volume to maintain adequate lubrication across its internal components.
  • Under normal use conditions, the 2.4 AWD transfer case follows a two-stage service schedule: a fluid check at 15,000 miles or 18 months, followed by a full fluid change at 30,000 miles or 36 months.
  • Under severe use conditions, the 2.4 AWD transfer case requires a fluid change at 15,000 miles or 18 months — the same interval at which only a check is called for under normal conditions, reflecting the accelerated wear associated with demanding operating environments.
  • The 3.5 V6 24V 4WD transfer case, across both the 2019-2021 and 2021-2022 model year groupings, specifies only a fluid check at 15,000 miles or 18 months under normal use conditions, with no change interval listed for that use category.
  • Under severe use conditions, the 3.5 V6 24V 4WD transfer case calls for a fluid change at 15,000 miles or 18 months, aligning with the same severe-use interval applied to the 2.4 AWD configuration.
  • The 3.5 V6 24V 4WD specifications appear across two overlapping model year ranges — 2019-2021 and 2021-2022 — with identical capacity and interval values in both, indicating no change in transfer case service requirements between those groupings despite the separate entries.
