Additional Notes

  • The Buick Encore GX automatic transaxle carries an overhaul capacity of 8.5-9.5 liters, which reflects the total fluid volume held within the unit when fully disassembled and refilled from dry.
  • The service fill capacity of 5-6 liters is notably lower than the overhaul figure, as a routine fluid change does not drain the torque converter, leaving a portion of the old fluid retained inside the transmission.
  • All four configurations listed across the 1.2 Turbo and 1.3 Turbo AWD variants share identical capacity values, with both the 8.5-9.5 liter overhaul and 5-6 liter service fill figures applying uniformly regardless of engine displacement.
  • The 45,000-mile change interval is tied specifically to severe use conditions across all listed configurations, meaning the interval applies under operating circumstances classified as more demanding than normal driving.
  • The 1.2 Turbo AWD and 1.3 Turbo AWD configurations each appear in two separate year range entries, with 2019-2022 and a later range beginning in 2022 listed for both engine variants, yet the transmission fluid specifications remain unchanged between the earlier and later entries for each engine.
