I recently had a tranny "power flush" performed at the dealer. Apparently this is a fluid exchange system. I had asked them to remove the pan and clean the screen as well, but they said that since it uses a screen and not a filter, they don't need to remove the pan and clean the screen because the power flush would take care of it. I'm pretty ignorant when it comes to auto trannies, so I thought I'd post this here and see what you guys think about this.
