there is no servicable internal trans filter on a honda. you may have an in-line filter up by the trans cooler (line to radiator) DO NOT USE ANY (insert name brand here) TRANS FLUSH products on hondas best results are drive til hot , drain,refill. repeat twice if necessary THAT is what honda considers a trans flush and it works best for their design.YES I do work at a dealer and YES I'VE replaced quite a few A/Ts shortly after they've been 'flushed' by aftermarket machines AND YES I do use 'those flush things' on other brands that seem to work well,...just not hondas. Thanks for putting up with my opinion. hope it's been a help!
