Is this causing any running issues or storing any codes?
The p0700 code means your scan tool is not sophisticated enough to retrieve the transmission codes from the module. This code just tells you there are codes stored in other modules. So you may need a better tool to find out which codes are stored. Codes would help us get this diagnosed easier and faster.
At this time it looks like the best choice is to OHM test all these wires you messed with from the switch to the module while both are unplugged. OHM test from each end of the wires while wiggling them to check for resistance, OHM test them to each other while wiggling to check for continuity and OHM test each to power and ground while wiggling them to see if there is continuity.
Thanks for asking your question and letting me try to help you.

I like to stay in contact with my customers. I assume you were not pleased with me or my answer since you did not rate it leaving me feedback. Just so you know we can still work on this issue. We can pick up where we left off or start over. I hate you paid all that money for your question deposit and have left not satisfied. Would any diagrams or repair guides or a phone call help?.
