What is your question?
Had transmission service (not by Toyota) worked great for about 2 weeks then started shifting hard. 3 light came on. Had error code checked and it said low on fluid or solenoids bad. Coincidentally battery went dead and had to replace. Once installed all codes cleared up and transmission work great again for about two weeks. Now service lights back on and shifts hard.

Shift solenoids could be potentially replaced, but are likely not the problem here. I would suspect more of a concern within the valve body or other components. Electrical concerns can be diagnosed with proper test equipment monitoring operation and testing circuitry. Jumping to any expensive conclusion would not be a good idea.
