Oh man, I can't agree with that enough! They do it on heavy equipment...but on an automotive application I bet its considered "unnecessary" by the planned obsolescent engineers.I've always thought auto transmissions needed a spin on filter that could be easily serviced but engineers don't seem to think so.
But on the Honda I would be thrilled with being able to drop the pan and change the filter...or change the filter in any way other than drop the drivetrain and split the trans cases wide open!
I also agree completely with changing the oil regularly, especially on these Honda trans...the one I just bought had the slightest studder occasionally, but it went away after an oil change (3.5 qts, not the full drain and fill, which requires 3x drain) and refill with Valvoline Maxlife ATF...which is what all our Hondas get.
Anyways...getting off in the weeds from the OP topic...
