Additional Notes

  • The automatic transaxle fluid capacity is 4.75 liters across all configurations of the Toyota Avalon XX20 for the 1999-2004 model years, covering both the Canadian and US market variants. A capacity at this level is typical of a service fill, meaning the volume required for a drain-and-refill procedure rather than a complete overhaul, which would require a larger quantity to account for fluid retained in the torque converter and valve body passages.
  • Canadian market specifications for the MCX20 3.0 V6 covering 1999-2002 and 2003 share identical service intervals: a fluid check at 16,000 km or 12 months and a fluid change at 48,000 km or 36 months. Both the distance and time thresholds must be considered, with service due when whichever limit is reached first.
  • The 2004 Canadian market MCX20 specification carries the same 16,000 km or 12-month check interval as earlier model years, but the change interval doubles to 96,000 km or 72 months. This represents a significant extension compared to the 48,000 km or 36-month change interval applied to the 1999-2003 Canadian configurations.
  • US market specifications for the MCX20 3.0 V6 across 1999-2004 do not include a fluid change interval under normal use conditions, listing only a check interval of 30,000 miles or 24 months. The absence of a change interval under normal use reflects a manufacturer position that fluid replacement is not required on a fixed schedule when operating conditions remain within standard parameters.
  • Under severe use conditions, the US market MCX20 specifications for 1999-2004 include both a check interval of 15,000 miles or 12 months and a change interval of 30,000 miles or 24 months. Severe use classifications typically apply to operating conditions such as frequent towing, extended idling, mountainous driving, or repeated short trips, all of which accelerate fluid degradation.
  • The severe use check interval of 15,000 miles or 12 months for the US market MCX20 is exactly half the 30,000 miles or 24-month check interval specified under normal use. This proportional relationship between the two use conditions is consistent across all US market model years from 1999-2004.
  • US market specifications remain unchanged across the 1999-2002, 2003, and 2004 model year groupings for both normal and severe use conditions. The intervals and capacity values are identical across all three groupings, in contrast to the Canadian market, where the 2004 model year received a revised change interval.
