07 4.8 trans fail after fluid/filter service

[MarcusE92]

I changed oil/filter along with sealing sleeve and the seals for the mechatronic. After reassembly and filling i drove the car maybe once. My wife drove it once after and the following day the dash lit up like a christmas tree faults were 2dca and cdb0 no messages from egs module. I found somewhere the plug could be the culprit but when trying to find more information i see none. Ive pulled the plug out and cleaned at least 3 times now plugged it back in and cleared the codes and it would run but in almost no time it comes back so I wonder if there is a poor connection. I tried finding repair pigtails or harnesses and outside of the entire engine harness i see none. Does anyone else have some insight into this they can help me with? Im about to pull the pan and the mecha again to make sure everything is OK or not.
