OK, I'm using photobucket to share the photos. I apologize that this followup has taken so long, but here goes.
This first picture is a far shot of the underside of the transmission with the pan and filter off.

Next here is a picture of the 4 solenoids (there are 2 solenoids on the opposite end of the valve body).

Here's a close up of the 4 solenoids.

All I did was loosen up the bolts holding the bracket in place. I did remove the one bolt on the end, but they may have not been necessary. All that was needed was enough clearance to slide the solenoid out. It came out very easy, no prying was needed. Here's a shot with the solenoid removed.

The new solenoid slid right in. I tightened up the bolts and put the connector back on. Very simple job. I would put the time at about 30-45 minutes for a novice to do the same.
While inspecting the valve body and pan, I found this little piece of what looks like gasket material.

My best guess is that it came from here as I can see what looks like a break in the continuity of gasket material partially sticking out.

I thought about the suggestion of adjusting the bands, but when I took a look at the studs for doing so, I though better of doing it right now. They were so rusted up that I didn't think that I would get an accurate adjustment.

I did spray (more like hose) them down with WD-40. I will spray them again when I go to change the filter and fluid again. The fluid looks and smells like trans fluid again. I did risk flooring the pedal one more time and now I only hear the sound from the transmission briefly with maximum torque. Since I never floor the pedal anyways, I'm going to just keep an eye on it and make a point of driving this explorer about once a week.
As for the gasket material, I think I'll wait on that too, unless anyone here thinks that putting it off has the potential to cause physical damage. This transmission has almost 170,000 miles on it and this is the closest to a major repair. I'm assuming it's a matter of time before something else requires attention and I can just redo the valve body when that happens. Let me know what you guys think of that strategy.
