Additional Notes

  • The Acura TL UA6/UA7 automatic transaxle carries two distinct capacity figures: a dry fill and a service fill. The dry fill represents the total fluid volume required when filling a completely empty transmission, such as after a full rebuild or replacement. The service fill reflects only the amount drained and replaced during a routine fluid change, which is always lower because residual fluid remains in the torque converter and passages.
  • For the TL 3.2 covering model years 2004-2008, the dry fill capacity is 7.2 liters. Both the 2004-2005 and 2006-2008 variants share this identical dry fill figure, meaning a complete overhaul or new unit installation requires the same total fluid volume across the entire 3.2-liter production span.
  • The service fill capacity for the TL 3.2 across 2004-2008 is 2.9 liters. At roughly 40 percent of the 7.2-liter dry fill total, the service fill volume reflects how much fluid a standard drain-and-fill procedure recovers, with the remainder staying trapped in the converter and valve body circuits.
  • The TL 3.5 Type-S for 2007-2008 carries a larger dry fill capacity of 7.7 liters, which is 0.5 liters more than the 3.2-liter variant. A larger displacement engine paired with a higher-torque output typically requires a transmission with greater internal volume, and the increased dry fill figure is consistent with a physically larger or differently configured transaxle unit.
  • Despite the difference in dry fill capacity between the 3.2 and the 3.5 Type-S transaxles, both share an identical service fill of 2.9 liters. The proportion of fluid recovered during a routine service is therefore smaller relative to total capacity on the Type-S, since the same 2.9-liter service fill represents a lower percentage of the 7.7-liter dry fill total.
  • All three configurations across the 2004-2008 Acura TL lineup are designated under normal use conditions. No severe-use interval or capacity variation is listed for any of the automatic transaxle rows, meaning the 2.9-liter service fill applies uniformly without a separate specification for demanding driving cycles.
