I pulled the tape off and the wiring is twisted together. But it has definitely been snapped in the past and looks as though whoever had it just tried to twist it together and then taped it.

I was just writing a response saying I looked at a couple other threads after searching those codes and it seems like people got those codes after bending pins on their mechatronic when reinstalling the TCU wire harness or breaking the connector on the shift assembly.

Assuming your pins are fine on your new mechatronic, it seems like you might've found the issue on your gear shift assembly? Maybe try splicing those wires to see if it fixes your issue and then pick up a shift assembly from a junk yard. I like using www.car-part.com, if you haven't heard of that before it's a network for junk yards to post items they have for sale.

For reference, here are the forum threads I looked at:
