Additional Notes

  • Across all GMC Acadia configurations covered — the 2.0, 2.5, and 3.6 V6 engines in both front-wheel-drive and AWD layouts, including the Denali trim — the automatic transaxle carries a uniform overhaul capacity of 8.5–9.5 liters. This range reflects the total fluid volume held within the transmission assembly when fully disassembled and refilled from dry.
  • The service fill capacity of 5–6 liters applies to all listed configurations regardless of engine displacement, drivetrain, or trim level. A service fill represents the amount of fluid exchanged during a routine drain-and-refill procedure, which is always lower than overhaul capacity because residual fluid remains in the torque converter and valve body passages.
  • The gap between the 5–6 liter service fill and the 8.5–9.5 liter overhaul capacity indicates that a standard drain-and-refill replaces roughly half to two-thirds of the total fluid volume. Full fluid replacement requires a complete overhaul or a multiple-cycle exchange procedure.
  • All specifications listed carry a severe use condition, under which the 45,000-mile change interval applies. Severe use typically encompasses operating patterns such as frequent towing, trailer hauling, stop-and-go driving, or sustained high-load conditions that accelerate fluid degradation.
  • The 45,000-mile change interval is consistent across every engine variant and drivetrain configuration in the Acadia lineup covered here, from the turbocharged 2.0 to the naturally aspirated 3.6 V6, under severe use conditions.
  • The 2.5-liter configurations — both FWD and AWD — share the same 8.5–9.5 liter overhaul capacity, 5–6 liter service fill, and 45,000-mile severe-use interval as the larger-displacement 3.6 V6 variants, indicating the same transmission unit is specified across those engine families.
  • The Denali trim variants of the 3.6 V6, in both FWD and AWD configurations from 2018-2022 and 2022-2023, carry identical capacity and interval figures to the non-Denali 3.6 V6 configurations, showing no transmission specification difference attributable to trim level alone.
  • Several engine and drivetrain combinations have overlapping year ranges, such as the 2.0 and 3.6 V6 configurations spanning both 2019-2022 and 2022-2023 as separate entries. The year 2022 appears in both ranges for those configurations, which reflects a mid-year or mid-cycle specification distinction rather than a change in the capacity or interval values themselves.
