Additional Notes

  • The Acura TSX CL9 automatic transaxle carries a dry fill capacity of 6.5 liters across all listed configurations for 2004-2008, a figure that represents the total fluid volume required when filling a completely drained or rebuilt unit with no residual fluid present.
  • The service fill capacity of 2.8 liters applies uniformly across all configurations, reflecting the smaller volume exchanged during a routine drain-and-refill where fluid retained in the torque converter and valve body is not displaced.
  • The gap between the 6.5-liter dry fill and the 2.8-liter service fill indicates that a standard service procedure replaces less than half the total fluid volume in the transaxle system.
  • For the TSX 2.4 (USA) 2004-2005 under normal use conditions, the automatic transmission fluid change interval is set at 144,000 km or 60 months, which is among the longest intervals listed in the specifications.
  • Under severe use conditions for the TSX 2.4 (USA) 2004-2005, the interval shortens considerably to 48,000 km or 24 months, matching the interval specified for the Canadian market under normal use conditions during the same model years.
  • The TSX 2.4 (USA) 2004-2005 specifications include a first change only interval of 192,000 km or 72 months, the longest single interval recorded across all rows, applicable exclusively to the initial fluid change on a new unit under non-severe conditions.
  • A separate first change only interval of 96,000 km or 36 months is listed for the TSX 2.4 (USA) 2004-2005 under severe conditions, indicating that even the initial service interval is halved when operating demands are classified as severe.
  • The Canadian-market TSX 2.4 2004-2005 carries a first change only interval of 96,000 km or 36 months under normal use, a figure that aligns with the severe-condition first change interval specified for the USA market variant of the same years.
  • The 2006-2008 TSX 2.4 rows carry no change interval in the specifications, with only the dry fill and service fill capacities listed, while the 2004-2005 rows for both markets include explicit interval data.
