Additional Notes

  • The Acura MDX YD1 3.5 V6 transfer case holds between 0.4 and 0.5 liters of fluid, a range typical of compact transfer cases where the exact fill level is confirmed by a check plug rather than a fixed volume.
  • Both the Canadian and USA market 3.5 V6 configurations share the same 0.4-0.5 liter capacity, indicating no regional difference in the transfer case unit itself across the 2003-2006 model years.
  • Under normal use conditions, the Canadian market MDX 3.5 V6 transfer case fluid change interval is set at 48,000 km or 24 months, whichever comes first.
  • The USA market MDX 3.5 V6 carries the same 48,000 km or 24-month interval under severe use conditions as the Canadian market normal use interval, meaning the severe schedule does not shorten the service period relative to the Canadian normal schedule.
  • A first-change-only interval of 72,000 km or 36 months is specified for the USA market 3.5 V6, applying exclusively to the initial fluid service rather than recurring maintenance cycles.
  • The first-change-only interval of 72,000 km or 36 months is notably longer than the 48,000 km or 24-month recurring interval, reflecting a factory-fill fluid formulation intended to last through the break-in period of the transfer case components.
