Cadillac XLR (USA / CAN)

Automatic transmission fluid capacity & service interval

Cadillac XLR (USA / CAN) requires automatic transmission fluid with a capacity range of 6,2 to 9 liters. Service intervals consist of 80000 km and 160000 km. The data covers 10 configurations.

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

Additional Notes

  • The Cadillac XLR 4.6 V8 for 2004-2006 uses a transaxle configuration, which places the transmission and drive axle in a single integrated unit, and I note a fluid capacity of 9 liters for that assembly.
  • Starting with the 2007-2008 XLR 4.6 V8, the unit is designated as a conventional automatic transmission rather than a transaxle, and the fluid capacity drops to 6.2 liters, a reduction of 2.8 liters compared to the earlier transaxle.
  • The 9-liter capacity of the 2004-2006 transaxle reflects the larger combined volume of a transaxle housing, whereas the 6.2-liter figure seen across all 2007-2009 configurations is consistent with a standalone transmission fill.
  • For the 2004-2006 XLR 4.6 V8, the normal-use change interval is 160,000 km, while severe-use conditions reduce that interval to 80,000 km, exactly half the normal figure.
  • The same 160,000 km normal and 80,000 km severe interval structure carries over unchanged to the 2007-2008 and 2009 XLR 4.6 V8 configurations, despite the shift from transaxle to transmission.
  • The XLR-V 4.4 V8 Supercharged, available for 2007-2008 and 2009, shares the identical 6.2-liter capacity and the same 160,000 km normal and 80,000 km severe change intervals as the naturally aspirated 4.6 V8 of the same years.
  • Across all 2007-2009 configurations, both the standard XLR and the supercharged XLR-V carry the same fluid capacity and service intervals, indicating no differentiation in transmission service requirements between the two engine variants.
