Additional Notes

  • The Buick Verano (USA / CAN) 2.4 automatic transaxle carries a fluid capacity range of 5 to 7.7 liters, which reflects a partial drain-and-fill figure on the lower end versus a more complete overhaul fill on the upper end.
  • Under normal use conditions, the 2.4 automatic transaxle fluid change interval is set at 97,500 miles, placing it among the longer-cycle transmission service schedules typical of modern sealed or semi-sealed units.
  • Under severe use conditions, the same 2.4 automatic transaxle carries a change interval of 45,000 miles, roughly half the normal-use figure, reflecting the added thermal and mechanical stress associated with demanding driving patterns.
  • The 5 to 7.7 liter capacity spread on the 2.4 transaxle is notably wide, a characteristic common to automatic transmissions where the actual fill volume depends heavily on whether the torque converter is drained during service.
  • Both the normal and severe service intervals for the 2012-2017 Verano 2.4 apply to the same 5 to 7.7 liter capacity range, meaning the fluid volume requirement does not change between service conditions, only the mileage trigger does.
