Does the Acura RDX have a transmission filter?
The Acura RDX uses a modern 10-speed automatic that includes a filtration screen inside the transmission, but there is no user-replaceable transmission filter cartridge. Routine maintenance focuses on the correct transmission fluid and intervals, with pan-service inspections when the pan is dropped.
Overview of the RDX transmission design
The RDX, especially in model years around and after the 2019 refresh, relies on a 10‑speed automatic transmission paired with the turbocharged engine. This transmission uses an internal fluid filtration system (a screen or screen/strainer) as part of its assembly. It is not sold or serviced as a standalone, replaceable filter like older, manual-service items. Acura service guidance emphasizes fluid maintenance and periodic inspections rather than replacing a separate filter element.
Is the transmission filter replaceable?
There is no conventional, consumer-replaceable transmission filter cartridge for routine maintenance on this transmission. If the pan is removed during service, technicians will inspect and clean the internal screen and replace the pan gasket as needed. Any filter-related work, if necessary, is typically handled as part of a full pan service rather than a standalone filter replacement.
Maintenance implications for owners
Follow the maintenance schedule in the owner's manual for automatic transmission fluid (ATF) changes and use the fluid specification recommended by Acura. In many cases, service involves a drain-and-fill or a more thorough pan-down procedure at the specified intervals or under certain driving conditions. If you notice shifting issues, slipping, or rough engagement, consult an Acura service center for diagnosis and appropriate service.
Summary
The Acura RDX does have an internal filtration system within its 10‑speed transmission, but there is no routine, replaceable transmission filter cartridge for owners. Maintenance centers on correct ATF type and intervals, with pan service for inspection when the pan is dropped.
