Thanks Tayto, and I appreciate your sentiments, but given everything it's not a terrible idea to replace 30 year old parts with new if they're even remotely suspect. The cost is minor, especially when weighed against what the 3 shops I took it to charged me to come up with nothing. I think it's probably a broken wire in the external harness. It could be the DRAC unit (not likely, given the speedo works) or it could be one of the internal issues you've described. The thing is this: Different than earlier periods of my life, nowadays I have slightly more money than time. Because of that it's far easier for me to shotgun blast approach the problem. IE, replace a bunch of parts and see what happens. If the transmission shops around here were better I'd be happy to pay them to figure it out. But that hasn't worked, so I'm back to buying parts and replacing them, working backwards from most likely to the least. Eventually I'll find the cause.
I've ordered a US shift stand-alone controller along with the wiring harness to fit it up. Before installing it I need to drop the pan again and install the Holley style solenoid it evidently requires. While there I'll air test the items you've mentioned and give the visual to the rest. When I had the pan down previously I carefully looked (and smelled) the remnants in the pan. There were no bits and pieces whatsover, and it didn't smell at all burnt. I'm not a novice around tools or metal fabrication, or machine shops. That's actually my 40+ year working background in a nutshell. But even with that, and even with the knowledge gained here or in the numerous articles I've read and the ATSG manual I've read cover to cover, it's still a bit of a challenge because automatics are new to me and this problem isn't neatly fitting into a diagnostic chart.
Again, thanks for the tips and advice, it's definitely appreciated.
