Hi, welcome to the forum.
Your posts will be easier to read if you do not type in all capital letters. Actron scanners have a code book, but it may be out of date or not include all codes.
I looked up the codes elsewhere & here is what they mean:
P0700 Transmission Control System Malfunction
U0073 Network: Control Module Communication Bus Off
Undoubtedly you have a computer issue of some sort. You may not be able to do so, but you could try a computer from a known good vehicle of the same year and see if the problem reappears.
You can read about the codes here:http://www.obd-codes.com/faq/obd2-codes-explained.php
