Additional Notes

  • All Cadillac XT4 configurations listed here share identical automatic transaxle fluid specifications, with an overhaul capacity of 8.5–9.5 liters and a service fill capacity of 5–6 liters.
  • The overhaul capacity of 8.5–9.5 liters represents the total fluid volume held by the transaxle assembly, including the torque converter and all internal passages, and applies when the unit is fully disassembled and refilled from dry.
  • The service fill capacity of 5–6 liters is the volume replaced during a routine fluid change, reflecting the amount that drains when the pan is dropped while residual fluid remains in the torque converter and valve body circuits.
  • Both the 350D diesel and 350T petrol variants, across front-wheel-drive and all-wheel-drive configurations, share the same 5–6 liter service fill range, indicating a common transaxle platform across the XT4 lineup in the EU market.
  • The 60,000 km change interval applies exclusively under severe use conditions. Severe use typically encompasses frequent towing, trailer hauling, repeated short trips, extreme temperature operation, or sustained high-load driving cycles.
  • The 350T petrol variant spans two separate year-range entries, covering 2020-2022 and a second entry starting from 2023, yet both carry identical fluid capacities and the same 60,000 km severe-use interval, indicating no specification change between those periods.
  • The 350D diesel configurations are listed from 2021 onward in both front-wheel-drive and all-wheel-drive forms, while the 350T petrol configurations begin from 2020, reflecting the diesel variant's later introduction into the XT4 range.
