Additional Notes
- The Acura MDX YD2 3.7 V6 (2007-2010) automatic transmission carries a dry fill capacity of 7.9-8.1 liters, reflecting the total fluid volume required when filling a completely drained or rebuilt unit, such as after a full overhaul where the torque converter and all passages are empty.
- The service fill capacity for the 2007-2010 3.7 V6 is 2.8 liters, which represents the amount of fluid returned during a routine drain-and-fill procedure, where residual fluid remains in the torque converter and valve body.
- The 2010-2013 3.7 V6 carries a dry fill capacity of 8.0 liters, a value that falls within the 7.9-8.1 liter range listed for the earlier generation, indicating close but not identical total system volume between the two production periods.
- The service fill capacity rises to 3.1 liters in the 2010-2013 3.7 V6, compared to 2.8 liters in the 2007-2010 version, a difference of 0.3 liters that points to a change in the transmission's internal fluid retention characteristics between the two configurations.
- Both configurations are specified under normal use conditions, meaning the listed capacities and intervals apply to standard operating environments rather than elevated-stress or severe-duty driving cycles.
- The gap between dry fill and service fill values across both configurations is substantial, with the 2007-2010 unit showing a difference of roughly 5.1-5.3 liters and the 2010-2013 unit showing a difference of approximately 4.9 liters, which reflects how much fluid remains trapped in the transmission during a standard service drain.
