I finally braved the cold outside to drive my Explorer up on ramps and take a good look at things on the transmission.
The lower electrical connection seemed (maybe) not all the way on, in spite of my earlier diagnosis, so I unplugged it and cleaned things up with some B-12 Chemtool cleaner and canned air.
When I put the plug back on, it didn't want to snap. Sure enough, when I had taken it off, it was not plugged in all the way (the snap connector hadn't "snapped").
I had to use a long flat screwdriver to gently get it to snap on.
And that fixed it. That's all the problem was -- that connector wasn't plugged in all the way. I went from having no 4th gear, no TC lockup, and no kickdown to having all three of those.
What an easy fix. I wish they were all like this.
I confirmed the KOEO codes (86 and 89) that I was getting are gone now, too. And my RPMs at 75 MPH are where they should be (2275 by my calculation, about 2350 on the RPM gauge).
