Hmmm, as far as I know, most Honda/Acura transmissions do not have a
serviceable transmission filter. I know this to be the case on my '03
Perhaps you should call the Acura dealer parts department to find out.
I would never take a late model Honda or Acura to anyplace which isn't a
specialist in the vehicles, either a dealer or and specialist
independent who works primarily on Acuras and Hondas. The days of
generalist mechanics being able to work competently on just about
anything are long over. Modern vehicles are complex and specialized.
For example, Honda uses an entirely different kind of automatic
transmission design than does just about anyone else. Honda also
requires a unique transmission fluid. Specialists should know this and
use the right stuff. General purpose garages either don't know or
believe fluid manufacturers who sell "all purpose" transmission fluids.
Bottom line, go to someone who knows what they are doing and who you
trust. Then you will not have to go ask stragers on usenet if you
should be worried.
