Additional Notes

  • The Acura TL UA8/UA9 3.7 SH-AWD transfer case fluid capacity is specified as a range of 0.4–0.5 liter across all covered model years from 2009-2014, rather than a fixed single value. A capacity expressed as a range typically reflects variation between a drain-and-refill service fill and the unit's total internal volume, accounting for residual fluid that may remain after draining.
  • The 0.4–0.5 liter capacity figure is notably small, which is consistent with a transfer case unit designed primarily for torque distribution rather than a large gear-reduction assembly. Units of similar size in other all-wheel-drive platforms commonly hold fluid volumes in the same sub-liter range.
  • All three specification rows carry a normal use condition, meaning the listed capacity applies to standard operating circumstances rather than a severe-duty or first-change-only service scenario.
  • The 2009-2010 and 2011-2012 model year groupings share an identical 0.4–0.5 liter capacity specification, indicating no change in transfer case fluid volume between the first and second production intervals of the UA8/UA9 generation.
  • The 2012-2014 grouping also carries the same 0.4–0.5 liter specification, meaning the transfer case fluid capacity remained consistent across the entire 2009-2014 span covered by the data.
