Additional Notes

  • The Buick Enclave 3.6L V6 automatic transaxle carries an overhaul capacity of 8.5-9.5 liters, a figure that reflects the total fluid volume held by the entire transmission assembly, including the torque converter and all internal passages when fully drained and refilled from a disassembled state.
  • The service fill capacity of 5-6 liters is notably lower than the overhaul figure because a routine fluid change does not evacuate fluid trapped in the torque converter, meaning only the portion accessible through the drain plug or pan removal is replaced during a standard service.
  • Under severe use conditions, a fluid change interval of 45,000 miles applies to the automatic transaxle across both the 2017-2022 and 2022-2024 model year groupings for the 3.6L V6.
  • No fluid change interval is listed for normal use conditions in any of the 3.6L V6 configurations, whether front-wheel drive or AWD, across either model year grouping. Only capacity values are specified for normal use.
  • The AWD variants of the 3.6L V6 share identical automatic transaxle capacity figures with their front-wheel drive counterparts, with both showing an overhaul capacity of 8.5-9.5 liters and a service fill of 5-6 liters.
  • The 45,000-mile severe-use change interval applies equally to the AWD configuration for both the 2017-2022 and 2022-2024 model year ranges, matching the interval specified for the non-AWD versions under the same conditions.
  • The overlap year of 2022 appears in both the 2017-2022 and 2022-2024 model year groupings across all configurations, indicating that 2022 model year vehicles are represented within both specification sets.
