My car has recently been showing signs of needing a new battery. The only real alarming issue was when the car threw a transmission warning and would not engage any gears. This was fixed by letting the car sit 10-20 minutes and restarting. The transmission never acted up, nor did the issue ever return.

I had a day off, so I took the car to an Indy dealer and he confirmed that I needed a new battery. He replaced and programmed the battery and mentioned that the transmission issue happened twice to him. Both times, it was fixed by walking away and restarting 10 minutes. The mechanic also took it for a test drive both times and mentioned it shifted just fine.

He obviously had a code reader, and pulled the following codes:

5073
5074
5A48
5A55

After searching a bit, my symptoms seem to be common along with the same 4 codes. However, none of the posts I found actually confirm what the issue was and how it was resolved.

I'm curious if anyone had this issue and what the ultimate solution ended up being? My mechanic is out for a few days, so I wanted to research a bit.
