Acura MDX, YD8, YD9, YE1 (USA / CAN)

Additional Notes

• All six configurations listed use a flexible service interval governed by an on-board maintenance system, meaning the transmission fluid change schedule is determined by the vehicle's own monitoring rather than a fixed mileage or time-based interval.
• The Acura MDX 3.0T AWD carries a single service fill capacity of 4.8 liters with no overhaul capacity listed, which reflects a sealed or otherwise non-overhauled transaxle design for that engine variant.
• The MDX 3.5 V6 in front-wheel-drive configuration specifies a service fill range of 3.2–4.3 liters. A range rather than a fixed value typically accounts for variation in how completely the old fluid drains before refilling.
• The overhaul capacity for the MDX 3.5 V6 front-wheel-drive configuration spans 7.3–8.3 liters, which represents the total fluid volume held throughout the entire transaxle assembly, including the torque converter, when fully disassembled and refilled.
• The MDX 3.5 V6 AWD configuration carries a higher overhaul capacity of 7.8–8.8 liters compared to the 7.3–8.3 liters of the non-AWD variant, reflecting the additional fluid volume associated with the all-wheel-drive transaxle hardware.
• The AWD variant of the 3.5 V6 also shows a higher service fill range of 3.7–4.8 liters versus 3.2–4.3 liters for the non-AWD version, consistent with the larger total fluid capacity of the AWD transaxle.
• Canadian and United States market specifications are listed separately across all configurations, yet the capacity values are identical between the two markets for each respective engine and drivetrain combination.
• The 3.0T AWD configuration begins with the 2022 model year, while all 3.5 V6 configurations begin with the 2021 model year, placing the turbocharged variant's introduction one year later within the covered range.
