Hi, I have a 2002 2300 Galaxy Auto. Just taken the auto sump off as its rusted through from the undertray being a huge sponge. I was planning on replacing the filter while I had the sump off, but I can't see how to get it out. Any ideas? Also sitting in the sump were these two plastic parts in the pics. I don't have any problems with the auto, so not sure what they are and I can't see where they might have come from. Any help appreciated, Adam..
