If you drop the pan, which I am 100% against for someone who has never done it before.. DO NOT PRY THE PAN OFF! This is where people bend the sealing surface of the pan and do not have the proper flat surface (and not a wooden block or work bench, that can make it worse) to get it correct. It always leaks after this.
If the pan does not come off within a reasonable amount of time of reasonable hammering with a rubber mallet, do not sweat it. The material in the bottom of the pan is where it would normally collect. I call this the pile of lies. This is because this is the pile of (normal) material that every transmission shop uses to to sell someone a new transmission. If it was really important to get out, a dealer would charge you to change that. Dealers will do anything to make a buck, and oddly this is one area they do not fool people into.
Don't get me tsrated on fuel injector cleaners though.
I have had many many cars including customers where I have not had to drop the pan, unless the "filter" is an actual filter and not a screen as in subarus. My own cars I do not drop them, and it is not out of lazyness, trust me. Just no need to do it and I would if I was afraid it would kill a tranny.
You can add an external filter, but even those have long service intervals. They are more apt to do a real filtering then the screen. Subaru does not call for this screen change ever.
