Cadillac DTS (USA / CAN)

Automatic transmission fluid capacity & service interval

Cadillac DTS automatic transmission fluid capacity ranges from 6,6 to 14,2 liters. Service intervals for fluid changes occur at 80000, 83000, 160000, and 166000 km. The data covers 8 configurations.

Additional Notes

  • The Cadillac DTS (USA / CAN) carries a notably large automatic transaxle fluid capacity across all model years, ranging from 6.6 to 14.2 liters depending on the year. Capacities at this scale are characteristic of a full fluid exchange rather than a partial drain-and-fill service.
  • The 2006 model year stands apart from the rest of the production run with a transaxle fluid capacity of 14.2 liters, more than double the 6.6-liter figure specified for the 2007 model year. A difference of this magnitude between consecutive years typically reflects a change in transmission unit or service procedure.
  • Starting with the 2008-2010 model years, the transaxle fluid capacity increased slightly from 6.6 liters to 7 liters, and the 2011 model year carries the same 7-liter figure, indicating a consistent specification across those three production periods.
  • For the 2006 model year under normal use conditions, the specified fluid change interval is 166,000 km. Under severe use conditions for the same year, the interval is halved to 83,000 km, reflecting the additional thermal and mechanical stress associated with severe operating conditions.
  • From 2007 onward, the normal use change interval is listed at 160,000 km across all remaining model years, a modest reduction from the 166,000 km interval specified for 2006 under the same use condition.
  • The severe use interval for 2007-2011 is consistently set at 80,000 km, exactly half of the corresponding 160,000 km normal use interval. A 2:1 ratio between normal and severe intervals is a common pattern in automatic transmission service schedules, reflecting the accelerated fluid degradation under demanding operating conditions.
