FYI here's my original trans after 18 years in my truck - kinda dirty but you can barely see the "upside-down U" there.2. I would add a photo of a '700 new enough to have the trans case molding seam--the crescent-shaped "upside-down U" casting mark that goes through the upper trans cooler fitting. Cases new enough to have that seam are also new enough to have most of the year-to-year "upgrades" for the troubles that plagued the early models. This crescent seam can be seen in the opening picture of your "700R4 Teardown and Inspection" video, but a better photo would be nice.
