Often, complex and challenging symptoms trace back to very simple issues caused by an oversight or two during reassembly. It's possible that a visual inspection could reveal the problem without spending time in diagnosis. A thorough visual inspection can reveal pinched wires, disconnected wires, connectors plugged into wrong places, damaged terminals or wires. A thorough visual inspection should never be skipped or rushed.
You should work to narrow the possibilities. Determining whether or not the problem is in the transmission can be very helpful.
Does your adx show calculated gear ratio?
Have you validated commanded shift solenoid state against the transmission gear?
See P. 48 of

1st gear should show solenoid 1 (or A) "On" and solenoid 2 (or B) "Off." Any other combination should not result in 1st gear. If the PCM is commanding the correct gear and the transmission is not responding appropriately then you may not need to chase the lack of speed data in your transmission adx.
Disconnecting the large connector at the transmission will force the transmission into 2nd gear. Removing power to the transmission will force the transmission into 2nd gear. If you cannot force the transmission into second gear by removing power from the solenoids then you have a problem inside the transmission. Conversely, if you remove power and the transmission remains in the same gear that it was in before you removed power, it would be very wise IMO to confirm (again, if necessary) the transmission is not actually in 2nd gear.
That's a good question. Check to see where the two files are getting data from by opening up the adx for editing. Solving this issue may not resolve the shifting issue but it could help you resolve this question so you can move to the next step.
So what has changed in the vehicle configuration between those logs and present day? Was anything changed in the calibration?
This seems unnecessary. If you could simplify this system it would reduce some unknowns now and in the future.
This is another area where a good visual inspection could be very important. And it's an area where it's challenging to see. I believe that it would be beneficial to see if the pcm is commanding 2nd gear. That is likely the fastest and least invasive test you can perform.
