I found interesting that the 2018 and newer GW's have three oil drain plugs and two oil filters. The traditional oil filter which is the same part number as the previous models. The second oil filter is for the DCT which is a small paper filter which requires an O-Ring. I am attaching a link to Fred Harmon's Video on changing oil on the new wings. I found it helpful and I also ordered several of the O-Rings he suggested.
I ordered the DCT filter and O-Ring from mrcycles.com
