I posted this last week to the "Red" forum but didn't get much response so I'll try here, too: I had the MCV out of my 454 and found this just behind it (at the bottom of the range transmission case), and I don't recognize it. It seems to be a complete part, not a broken-off portion of something else. Transmission and hydraulics work well and there's evidence that other folks have been in there over the years, so in all likelihood it was dropped in there during a long-ago repair, but I'm curious where it comes from (maybe it's part of a tool rather than a tractor part). Any ideas? Thanks!
