Additional Notes
- The BMW X6, E71 / E72 (USA) automatic transmission fluid capacity varies by configuration, ranging from a fixed 8.5 liters on certain variants to a span of up to 10 liters on others, reflecting differences in transmission unit design and fill procedures across the lineup.
- The X6 M (2008-2014) carries a capacity range of 9 to 10 liters for its automatic transmission fluid, which is consistent with a service fill figure that accounts for variation in residual fluid retained within the transmission during a drain-and-fill procedure.
- The X6 xDrive35i in its 2008-2010 form specifies a capacity range of 9 to 9.5 liters, while the 2010-2014 version of the same variant drops to a fixed 8.5 liters, indicating a meaningful difference in transmission fluid volume between the two model year groupings despite sharing the same nameplate.
- The X6 xDrive50i follows a similar pattern to the xDrive35i, with the 2008-2010 version specifying a wider capacity range of 9.4 to 10 liters and the 2010-2014 version settling at a fixed 8.5 liters, suggesting a transmission unit change occurred around the 2010 model year for both non-M variants.
- A fixed capacity value such as 8.5 liters, as seen in both the 2010-2014 xDrive35i and xDrive50i, typically reflects a more precisely controlled service fill with less tolerance for variation, compared to the broader ranges specified for earlier model years.
- The X6 xDrive50i (2008-2010) has the widest capacity range in the lineup at 9.4 to 10 liters, a spread of 0.6 liters, which in automatic transmission service generally accounts for differences in how completely the torque converter and cooler lines drain before refilling.
- All five configurations across the BMW X6 E71 / E72 (USA) share a uniform 100,000-mile change interval under normal use conditions, applying consistently regardless of engine type or model year grouping within the 2008-2014 range.
