Additional Notes

  • The Acura TL UA8/UA9 3.7 SH-AWD rear differential capacity is specified at 2.5-2.8 liters across all listed model years from 2009-2014, reflecting a service fill range rather than a single fixed value.
  • A capacity range of 2.5-2.8 liters, as opposed to a single precise figure, is typical of a drain-and-fill service procedure, where the amount of fluid accepted can vary slightly depending on how completely the old fluid drains before refilling.
  • The 2009-2010 3.7 SH-AWD rear differential carries an alternative (acceptable) use condition alongside the normal condition, both sharing the same 2.5-2.8 liter capacity specification.
  • The 2011-2012 and 2012-2014 3.7 SH-AWD configurations each carry only a normal use condition for the rear differential, with the same 2.5-2.8 liter capacity retained across both ranges.
  • The overlap at model year 2012 across two separate row entries, one covering 2011-2012 and another covering 2012-2014, indicates a mid-cycle specification revision point, though the rear differential capacity value of 2.5-2.8 liters remains unchanged between the two.
  • All listed configurations apply exclusively to the SH-AWD variant of the 3.7-liter TL, as front-wheel-drive TL trims do not carry a rear differential and therefore have no corresponding fluid capacity entry.
