Additional Notes

  • The Cadillac XT6 (USA / CAN) rear differential holds 0.75 liter across all AWD configurations, covering both the 2.0-liter and 3.6 V6 engine variants.
  • A separate rear differential clutch assembly carries its own fluid fill of 0.35 liter, a notably smaller volume that reflects the clutch pack's distinct housing rather than the main differential cavity.
  • Under normal use conditions, the rear differential fluid change interval is set at 150,000 miles for all listed AWD configurations, both 2.0 and 3.6 V6.
  • Under severe use conditions, the rear differential fluid change interval is halved to 75,000 miles, applying equally to the 2.0 AWD and 3.6 V6 AWD across all listed model years.
  • The rear differential clutch specification carries no change interval in the data, only a 0.35-liter capacity figure under normal use conditions, for all AWD variants listed.
  • The 3.6 V6 AWD appears under two separate configuration entries, one covering 2019-2022 and another starting from 2022, with both sharing identical rear differential and clutch fluid capacities and service intervals.
  • The 2.0 AWD similarly appears under two entries, one for 2020-2022 and one starting from 2023, with rear differential and clutch specifications remaining consistent between the two.
