Automatic transmission fluid capacity & service interval

Cadillac XT4, E2XX (USA / CAN) automatic transmission fluid capacity ranges from 5 to 9,5 liters. Service intervals require a change every 45000 miles. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Cadillac XT4 2.0 transaxle automatic carries an overhaul capacity of 8.5–9.5 liters, a range that 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 is notably lower than the overhaul figure, which is expected since a routine drain does not evacuate fluid retained in the torque converter and other internal passages.
  • All four configurations listed — the 2.0 FWD and 2.0 AWD variants across both year groupings — share identical capacity values of 8.5–9.5 liters for overhaul and 5–6 liters for service fill, indicating no capacity difference between the front-wheel-drive and all-wheel-drive transaxle setups.
  • The 45,000-mile change interval applies under severe use conditions across every listed configuration, meaning the interval is not tied to a normal-use schedule in the specifications provided.
  • Severe use conditions generally describe operation involving frequent short trips, towing, trailer pulling, or stop-and-go driving, all of which accelerate fluid degradation and justify a shorter change interval than normal use.
  • The 2018-2022 and 2022-started groupings for both the FWD and AWD variants carry the same 45,000-mile severe-use interval, showing no change in the service schedule between those year groupings.
