Acura MDX, YD3, YD4 (USA / CAN)

Additional Notes

• The transfer case fluid capacity across all listed Acura MDX 3.5 V6 SH-AWD configurations from 2013-2020 is 0.43 liter, a figure consistent with a service fill rather than a full overhaul quantity, as transfer cases of this size typically hold only a small volume of fluid relative to other drivetrain components.
• The 2013-2015 MDX 3.5 V6 SH-AWD transfer case specification carries a normal use condition, meaning the 0.43-liter capacity figure applies to standard operating circumstances without a separately defined change interval in the listed data.
• For the 2016-2020 MDX 3.5 V6 SH-AWD in Canada, severe use conditions correspond to a transfer case fluid change interval of 48,000 km alongside the 0.43-liter fill capacity.
• The U.S.-market 2016-2020 MDX 3.5 V6 SH-AWD carries a shorter severe-use change interval of 30,000 miles compared to the Canadian market's 48,000 km under the same condition, reflecting a difference in how each market's specification is expressed.
• Both the Canadian and U.S. 2016-2020 MDX 3.5 V6 SH-AWD specifications include a flexible interval tied to the on-board maintenance system, where the 0.43-liter capacity applies but no fixed mileage or kilometer interval is assigned in the listed data for that condition.
• The separation of Canadian and U.S. specifications beginning with the 2016 model year, where no such split exists for 2013-2015, indicates that regional market distinctions were introduced at that point in the MDX's service documentation.
