Acura TSX, CU2 (USA / CAN)

Additional Notes

• The Acura TSX CU2 2.4-liter automatic transaxle carries a service fill capacity of 2.4 liters, a figure that applies uniformly across both the 2009-2010 and 2011-2014 model year spans.
• A service fill capacity reflects the volume of fluid displaced during a routine drain-and-fill procedure, not the total system volume, which means the 2.4-liter figure for the 2.4-liter engine represents only the fluid that drains from the pan during a standard service.
• The TSX 3.5 (USA) automatic transaxle lists both a dry fill capacity of 7.5 liters and a service fill capacity of 3.3 liters, making a clear distinction between a complete overhaul fill and a routine maintenance fill.
• The dry fill value of 7.5 liters on the 3.5-liter transaxle represents the total fluid volume required when filling a completely empty or rebuilt unit, a scenario typically encountered after a full transmission overhaul or replacement.
• The gap between the 7.5-liter dry fill and the 3.3-liter service fill on the 3.5-liter transaxle indicates that approximately 4.2 liters of fluid remains in the torque converter and other passages during a standard drain, which is a common characteristic of automatic transmission service procedures.
• The 3.5-liter transaxle service fill of 3.3 liters is notably higher than the 2.4-liter engine's 2.4-liter service fill, a difference consistent with the larger physical size and greater fluid capacity of a six-cylinder automatic transaxle compared to a four-cylinder unit.
• All four rows across both engine variants and both year groupings are designated under normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty cycles.
• The 3.5-liter transaxle specifications remain identical between the 2009-2010 and 2011-2014 periods, with both the 7.5-liter dry fill and 3.3-liter service fill values unchanged across the full model range.
