Trans wiring harness issues. 4x4, trans malfunction, DBC, DSC, AWD, brake light on

I get a 4x4, trans malfunction, DSC, DBC, AWD, brake, and sometimes no lights on the automatic transmission shifter at all... which then means you have a non starting car. At first, if i crawled under the car and wiggled the wires of the plug at the transmission's mechantronic unit sleeve, it would work again... for awhile.

Here are some old codes from Aug of this year that might help? (i did change all my lights at this point, which i think is the reason for those codes) Recent codes are in post #7-8

While I was changing the trans fluid and mechatronic sleeve, I noticed the 90 degree Plastic cap, (that the wires run through into the twist lock of the mechantronic sleeve) was opened up and sitting on there loosely. So I proceeded to stuff the wires back in there properly and thats when the lights started. I think. So i left them in there loose again.

Does this look like the start of a failing transmission ecu?
