I'll be interested to see what you ultimately discover on this. I'm not very familiar with the details on the transmission, otherwise I'd try to offer some support. Hopefully others here are more familiar and will offer help.
Me too, if I can't get any help soon. Guess I'll start with solenoid pack. Then vavle body. Then servos. From what I have researched there the most common for failer.
There's also the chance that one or more of the servo bores are worn. There's a sleeve kit available to fix that, and it's not much extra labor by the time you get to the valve body.
Ok, now I have replaced both servos with AJ1E servos, replaced valve body and solenoid pack with new. And still have the same problems and codes. Except for the tc being stuck or locked out. Have not checked line pressures . can do that again tomorrow. Any help would be great. Thanks
Looking through the factory service manual for those codes, it seems like there's not much more troubleshooting that can be done without a factory-like scan tool to put the transmission in "bench mode" and taking measurements.
About the only thing I've seen in the list that I don't see you've checked yet is to confirm the integrity of the wiring to the transmission. Since so many of the codes are similar in nature, it does seem feasible that there may be a wire or two that is damaged/corroded and could explain most of the codes.
