Additional Notes

  • The GMC Acadia rear differential holds 0.75 liter across all AWD configurations covered in these specifications, including the 2.0, 2.5, and 3.6 V6 variants. A consistent capacity across engine families typically reflects a shared rear drive module design rather than unit-specific hardware.
  • The rear differential clutch pack is a separate fluid circuit from the main differential housing. At 0.35 liter, the clutch capacity is notably smaller, reflecting the limited volume of the electronically controlled coupling assembly that manages torque distribution between the front and rear axles.
  • Under normal use conditions, the rear differential fluid change interval is set at 150,000 miles for all AWD configurations listed. This extended interval is associated with sealed or semi-sealed rear drive modules where fluid degradation under typical driving loads is considered gradual.
  • Severe use conditions reduce the rear differential change interval to 75,000 miles, exactly half the normal-use figure. Severe use generally encompasses frequent towing, trailer hauling, off-road operation, or repeated short trips, all of which accelerate fluid thermal breakdown and contamination.
  • The 2.0 AWD configuration appears in two overlapping specification groups: 2019-2022 and 2022-2023. Both groups carry identical capacity and interval values, indicating no change to the rear differential specifications at the 2022 model year boundary for that engine variant.
  • The same overlap pattern applies to the 3.6 V6 AWD and 3.6 V6 Denali AWD configurations, each listed separately for 2018-2022 and 2022-2023. The Denali trim shares identical rear differential and clutch capacities with the non-Denali 3.6 V6 AWD, pointing to the same rear drive hardware regardless of trim level.
  • The 2.5 AWD configuration is listed only for 2018-2021 and does not appear in a subsequent overlapping group, unlike the 2.0 and 3.6 variants. The rear differential and clutch specifications for the 2.5 AWD are identical in value to all other AWD configurations in the dataset.
