Ok. I pulled the solenoids/sensors out of my core 46RE earlier tonight so I can mess around with them. Later I'll order the $50 harness from flebay so I can hook up to it easier. Slowly moving forward

There's another guy online that sells a box that takes an electronic speed signal, then drives a stepper motor to spin the speedometer cable.
We'd have to get that, or I may end up building one of those as well.

This is a product that the Durango/Dakota/Jeep guys would love to have. 42/44/46RE's
It would be so nice to use a different ECM like a Megasquirt without having to piggyback on the stock JTEC and hoping you don't do something to kick it into limp mode. Or even ditch the EFI all together and use a carb if you want.
I searched the megashift forum and never found where anyone had really made any progress adapting it to a Mopar trans.

That was kinda the idea. For myself, I'm looking at doing the Ford 5.0 EFI, and would need either this controller, or an RH transmission.
Last I checked, one guy had made the megasquirt trans controller work with an RE, but you have to find the right circuit boards and the right code, and then make it work. I'm aiming for an OOTB solution.
My controller will need to know the vehicle speed, so it will either need to: A - use a speedometer cable pass through that generates an electronic signal that goes to the controller (like this http://www.summitracing.com/parts/SUM-G2887-1/) or B - Use the electronic speed signal from the trans, and then drive a stepper motor to work with cable driven speedometers.

AutoMeter sells a speed sensor/speedo drive for about $80

Ok transmission experts...
If I built a test rig with the engine/trans outside of a vehicle, would I need to put the transmission under load to properly test everything (governor pressure, etc)?
Or could I get away with just running it and taking my measurements?

You would need to manipulate the throttle valve in relation to an imagined "load" to test it but it sounds like you just need to manipulate the gov. press. strictly in relationship to the output shaft RPM. For simplicity you could ignore the temp and just make the pressure go up in relation to RPM.
Another thought I had about this the other day was while watching them on the datastream on my scanner shows them to jump up or down in big steps rather than smooth rise and fall like the computer is trying to command an exact shift time rather than a smooth rise and fall where the trans just shifts but I would expect it to work just fine with gradual rise and fall in relation to RPM.

One thing to probably remember is the stock calibration would probably be geared more towards smooth soccer-mom friendly shifts. We as gearheads are typically more interested in solid quick gear changes.
