Hi, to Toyota Nation hope all is well with everyone. This may be a bit wordy so I apologize in advance lol. So this is how this story goes, a family member originally owned this corolla, they say one day it just stopped moving, no forward or reverse, they towed it home and parked it and it sat for at least a year. They were going to get rid of it and because I they know that I do as much of my own maintenance as I can they gave it to me. Now I will first start off by saying that I'm not or I wasn't a transmission mechanic until about two weeks ago lol 
😁🙂 however I'm enjoying the challenge and so far I've learned how to disassemble and reassemble the a245e transmission valve body. Now here's a synopsis of what I've did so far and where I am now. I pulled the codes and based on that result I removed the pan, the pan had what I would consider expected where for a tranny with 200k + miles on it. I found one very small piece of metal maybe an 8th of an inch, the fluid was reddish brown but not black, you could see slight glistening in the bottom of the pan similar to what one would see when panning for gold but in my humble opinion it wasn't heavy enough to cause the car to suddenly stop moving in drive or reverse, there was also some sediment on the magnets. I first did electrical checks of the solenoids resistance at the plug, they were all within range per the manual, I then removed the solenoids and rechecked the resistance directly with the same result. I then checked the T.C.C. , A & B solenoids with 12 volts, the A&B solenoids had a very strong click but the T.C.C. solenoid had a much softer click, it was not as noticeable as the A&B solenoids. I then removed the valve body, some of the actuators did not move freely or would stay depressed when I pushed them. Per the manual I took it apart/cleaned/reassembled and now all parts move freely. I reinstalled the valve body along with a new filter and transmission fluid
(Valvoline MaxLife Multi-Vehicle Automatic Transmission Fluid). Now when I shift into reverse/drive you can feel the car drop into gear but there is no wheel movement, the rpm's rise then settle as you shift through the gears, currently I still have the car front end on jacks. I find it interesting that all of the codes point to a possible electrical issue and not necessarily a mechanical hardware failure so my next move is to do point to point continuity checks of the associated wiring. Also the fact that all of the solenoids are reporting faults makes me wonder if the computer could be the issue as it is the central point. I'm hoping to gain greater insight that will help me to possibly pinpoint what maybe causing this issue and Ideas to help me correct it without necessarily having to replace the transmission plus it would really be cool to make this transmission work if that's possible, actually I'm enjoying this challenge, it's like the ultimate puzzle and all help is appreciated.
Below are the pulled codes.
