Hey, I am new to this forum and on my second cub. I had an lt1024 that I blew the trans in and I bought a new gt2550. I too, discovered this oil changing issue; my dealer is looking into it for me.
What I noticed is after looking at the parts list for the gt2550, cc has a straight pipe with a 90 degree fitting on the end and the plastic piece of ... attached to the elbow. So it appears to me that cc knows the issues, and has a solution, but it is not being updated on equipment at the dealer side or (even worse) at the factory. All of the parts lists that I have downloaded have this "new" diagram.
Just thought I would through my two cents in, or is it a quarter now for inflation.
