How the hell does water get into that connection?! Does it come down the inside of the insulation bundle? There is a tight rubber boot that was filled with water?
When I'm done cleaning I'm going to fill the boot with silicone and maybe cut a drip hole in the insulation sleeve especially if I can confirm the wire bundle is working like a hose to supply water to the connector!
When watching the real-time values on the transmission switch pins I was surprised to see closed switches when they should be open and that wouldn't happen from a corroded contact inside the selector switch.
Rusty water however is slightly conductive so I'm pretty confident my problem was just found. I wish I took video of removing that connector! About half an oz. or more of red colored water peed out!

Glad you found that!
I can't tell you how much grief I went through with misdiagnosis of the error messages at the dealer. Going through a car wash with an undercarriage spray finally led them to that connector. Mine looked exactly the same.
I had the same type of problem with my engine harness after hitting 14 inches of water during a Texas spring downpour. Every possible error code the engine could throw was recorded.
Turned out there was no grease in any of the harness connectors from the factory. Fortunately, my insurance covered the $1800 bill under storm damage.
