How much transmission fluid does a 2014 Acura RDX take?
For a 2014 Acura RDX equipped with the 6-speed automatic transmission, the typical total capacity is about 9 quarts (roughly 8.5 liters) for a full system fill. A simple pan drain and refill usually requires about 4–5 quarts, while a complete flush could use around 9–11 quarts depending on the method and how much fluid remains in the torque converter.
In practice, the exact amount you need depends on the service you choose (pan drain and refill vs. full flush), the current fluid condition, and whether the transmission fluid is being replaced along with a filter. It’s important to use the correct ATF specification and to follow the vehicle’s service procedures. The typical fluid type for this model is Honda/Acura DW-1 ATF or an equivalent that meets the manufacturer’s specification.
Capacities at a glance
The numbers below reflect common service options for the 2014 RDX. They assume standard drains and refills and do not account for any unusual conditions.
- Pan drain/refill capacity: about 4.5 quarts
- Total system capacity: about 9 quarts
- Recommended ATF: Honda/Acura DW-1 ATF (or equivalent per the owner's manual)
These figures help plan a service and ordering the correct amount of fluid. For a thorough replacement that includes the torque converter’s fluid, you may need more than the pan capacity.
Service options and recommendations
Below are common service approaches and what to expect in terms of fluid requirements. Always consult the owner's manual or a certified technician for vehicle-specific guidance.
- Pan drain and refill: Drain the pan, replace the filter if applicable, reinstall the pan with a new gasket, and refill until the dipstick indicates the correct level. Typical fluid needed: 4–5 quarts.
- Full transmission flush: Uses equipment to circulate new fluid through the system and displace old fluid more completely. Typical fluid needed: 9–11 quarts, depending on the method and how much fluid remains in the torque converter and cooling lines.
- Filter replacement: If your model’s transmission has a replaceable filter, changing it is commonly done during a pan service and contributes to the total fluid capacity used during the job.
Note: A professional flush may yield better results in some cases, but it requires specialized equipment. If you’re doing it yourself, ensure you have the correct procedure and the right ATF type.
What you’ll need
- ATF type: Honda/Acura DW-1 (or an equivalent that meets the manufacturer specification)
- Appropriate quantity of ATF (roughly 9 quarts for a full replacement, with 4–5 quarts needed for a pan drain/refill)
- New transmission pan gasket (if removing the pan) and a clean drain pan
- Basic hand tools, a funnel, a torque wrench, and safety equipment
Always verify the exact specification and capacity in your owner's manual, and consider having a dealership or qualified shop perform the service if you’re unsure about the procedure.
Summary
For the 2014 Acura RDX with a 6-speed automatic transmission, plan around 9 quarts for a full system fill and roughly 4–5 quarts for a simple pan drain and refill. A full flush can require 9–11 quarts, depending on the method and the amount of fluid retained in the torque converter. Use Honda/Acura DW-1 ATF and follow the vehicle-specific service procedures to ensure proper transmission performance and longevity.
