E4OD Will not downshift

My transmission is stuck in 3rd or 4th gear. It has reverse and works fine. I can manually shift and it down shifts fine, just wont automatic shift. This problem happened after one nights sitting. I removed the solenoid pack wiring and it had some frayed wires I repaired them and apparently that was not the problem. I am getting power down to the plug in for the solenoid pack.

I do not have a code reader but found out how to read them with a volt meter.

Here is the video of the codes.
Can anyone decipher if for me?


If I am getting power down to the transmission that means no bad relays right? I cant tell if its an electrical problem or mechanical problem. Also I do not have a flashing OD light.
