Additional Notes

  • The Toyota Avalon XX40 3.5 V6 24V automatic transaxle holds 6.5 liters of fluid across all listed configurations, covering both Canadian and US market variants for 2013-2018.
  • A 6.5-liter capacity in an automatic transaxle typically reflects a full service fill figure, meaning the amount required when the unit is drained and refilled during a fluid change procedure.
  • Under normal use conditions, the Canadian GSX40 specification calls for a fluid check at 16,000 km or 12 months, with no scheduled drain-and-fill interval attached to that condition.
  • Under severe use conditions, the Canadian GSX40 adds a fluid change interval of 96,000 km or 72 months on top of the same 16,000 km or 12-month check schedule.
  • The Canadian specification includes a first-check-only condition, placing an initial fluid inspection at 32,000 km or 24 months, which is a one-time early service point separate from the recurring normal and severe schedules.
  • The US market GSX40 under normal use conditions sets the fluid check at 30,000 miles or 36 months, a notably longer interval than the 16,000 km or 12-month check specified for the Canadian market under the same condition.
  • Under severe use conditions, the US market specification introduces a fluid change at 60,000 miles or 72 months, while the Canadian severe specification sets the change interval at 96,000 km, which converts to roughly 59,650 miles, placing both markets at a closely aligned change threshold despite differing unit systems.
  • The 72-month time limit on the fluid change interval is consistent between the Canadian and US severe use specifications, indicating a shared maximum service life by time regardless of market.
