Additional Notes

  • The Cadillac CT4 transfer case holds 0.8 liter of fluid across all listed AWD configurations, covering the 2.0-liter, 2.7-liter, and CT4-V 2.7-liter variants. A capacity at this level is consistent with a compact transfer case unit designed for a car-based AWD platform rather than a truck-based four-wheel-drive system.
  • The 0.8-liter figure represents a service fill capacity, meaning the amount of fluid required during a routine drain-and-fill procedure. Transfer case service fills are typically lower than full overhaul capacities, which would account for residual fluid retained in internal passages and components.
  • Under normal use conditions, the transfer case fluid change interval is set at 97,500 miles for all listed CT4 AWD variants. This interval applies uniformly to the 2.0 AWD, 2.7 AWD, and CT4-V 2.7 AWD configurations across both the 2019-2022 and 2022 starting year entries.
  • Under severe use conditions, the transfer case fluid change interval drops to 45,000 miles, which is less than half the normal-use interval of 97,500 miles. Severe use typically encompasses operating conditions such as frequent towing, trailer hauling, extended idling, or driving in extreme temperatures, all of which accelerate fluid degradation.
  • The 2.0 AWD and 2.7 AWD variants share identical transfer case fluid capacity and change intervals under both normal and severe conditions. No specification differences exist between the two engine displacements in relation to the transfer case service data.
  • The CT4-V 2.7 AWD carries the same 0.8-liter capacity and the same 97,500-mile normal and 45,000-mile severe change intervals as the standard CT4 2.7 AWD. The CT4-V designation, which identifies a higher-performance trim level, does not correspond to any variation in transfer case fluid service specifications.
  • Entries for the 2019-2022 range and entries starting from 2022 carry identical capacity and interval values across all three AWD configurations. The 2022 starting year entries represent a separate specification grouping but reflect no change in transfer case fluid service requirements relative to the 2019-2022 grouping.
