Unclear Transmission issues- total fail or what?

searching that code ehre on TW came up with a couple posts about a loose pin on the transmission wiring harness.

 

What ended up being your issue with all the codes? I have the identical codes that I am chasing down. Help would be great if you found a resolution.

Assuming possible wiring issue?? bump
Thank you for any replies

 

Wondering though if anyone else had the same issue----- I feel like it is either a low transmission fluid level issue or solenoid issues. I was also told by dealer needs new transmission but completely disagree. Tacoma drove smooth until one day. Makes no sense for a complete new transmission. I am a chiropractor and love to diagnose, I have also worked on my own vehicles for years and have self dig nosed and love fixing my own vehicles hence always being poor growing up and have always fixed my own vehicles. They just came to the conclusion due to the codes that just popped up. Was bought by a 1 time owner who was an older gentleman who garaged and kept tacoma well kept and taken to dealer for maintenance since new. He was a government worker who I trust. All highway miles and well taken care of. I have in the past done tranny and rebuilt motors and feel like it is a simple fix rather than a new tranny

 

Shifting is smooth, there is just now the random slipping when driving and the codes for shift solenoids.

 

I drained some fluid and no metal

 

Possibly electrical after moving out to a farm about a month before due to mice or the possible corrosion I am aware of but with the hard winters it ha been hard to look for and since I just moved I don't have my garage.
