It's fixed. Wound up being the servo. Sorry no pics, but here's what I did.
I tried to adjust the band, and it did get tight, so I ruled that out. From what I read on here, it appeared that the solenoids don't cause a no gear condition, but more flare ups and shifting issues. I decided to try the servo first. Put the explorer on 4 ramps, crawled under, and tried to loosen the cat pipes. No go. I didn't want to snap any bolts, so I decided to forego that step (the hard way is always the more fun way). I pulled out the heat shield above the pass side cat, and removed the snap ring. I didn't have any 90 degree needlenose pliers, so I improvised.
I've rebuilt a few TH350 transmissions, and on the side of the case is the 1-2 accumulator cover. There is a snap ring that holds it on, and a small hole drilled in the case you use to pop it off. All you need to do is push a centerpunch or nail in there, and it can be removed. I decided to do the same on this.
I took my drill and CAREFULLY drilled a small hole in the case right into the snap ring groove. I then pushed a carpenters nail into the hole, gave it a few light hammer taps, and moved the snap ring up. Then using 2 small screwdriver and becoming a contortionist (friggin cat in the way!), removed the ring from the groove. I then used 2 small screwdrivers to work the cover off the servo. Guess what? Servo piston had broke off the pin. Put the new servo in, shifts perfect now.
A big thanks to everyone that helped. I think it's possible to also remove the intermediate servo with the cat still there, but looks much tighter!
