Additional Notes

  • The Toyota Avalon XX30 3.5 V6 automatic transaxle carries a dry fill capacity of 8.8 liters for the 2005-2007 model years in both the USA and Canadian markets. Dry fill represents the total fluid volume required when filling a completely empty transmission, such as after a full overhaul or replacement of the unit.
  • Service fill capacity for the 2005-2007 GSX30 transaxle is 3.5 liters, which is the volume needed to replenish fluid lost during a routine drain and refill. The gap between the 8.8-liter dry fill and the 3.5-liter service fill reflects the volume of fluid retained in the torque converter and valve body during a standard service procedure.
  • From 2008 onward, the Canadian-market GSX30 specifications list only a single 6.5-liter capacity figure, without a separate dry fill and service fill distinction. The same applies to the USA-market 2008-2012 entries, which also carry a single 6.5-liter capacity value.
  • The Canadian-market specifications include a fluid change interval of 96,000 km or 72 months across all GSX30 model years from 2005-2012, applied under normal use conditions. No equivalent change interval appears in the USA-market normal use entries for any model year.
  • USA-market entries for the 2005-2007 GSX30 include a severe use condition row that adds a fluid change interval of 60,000 miles or 72 months. Under normal use conditions for the same years, no change interval is listed, only a check interval of 30,000 miles or 36 months.
  • The check interval for the Canadian-market GSX30 is set at 16,000 km or 12 months across all model years from 2005-2012. The USA-market equivalent check interval is 30,000 miles or 36 months, reflecting a different service scheduling framework despite covering the same vehicle and transmission.
  • The severe use condition for the USA-market 2005-2007 GSX30 carries the same check interval as the normal use condition, at 30,000 miles or 36 months. The only additional specification under severe use is the explicit 60,000-mile or 72-month change interval.
