The engine light went on and it said to check transmission.

What is your question?

My car didn’t want to start. We found out it was the battery. When I turned it on it said check transmission. Now the engine light is on. Before all this occurred my car would make a weird noise when I tried to turn it on. The gas indicator would take a long time to show how much gas in my car. It never did this before. I always have my gas tank half full, so I didn’t need gas. Then all of a sudden it didn’t start. I have a 2017 Ford Focus.

How long has your 2017 Ford Focus had this problem?

For a week.
