New gears

So I just had 4.88 gears installed on my 2015 JKUR and on the way home the jeep seemed be to stuck in first gear. The rpm gauge would follow the speedometer (55mph=4000rpm) and then the check engine light came on. And on top of this the battery had to be jumped when I got the jeep back.

Being a newer engine and everything being electronic could the battery be causing the issues?

And yes I had a Superchips Flashcal installed with my tire and gear size. Thanks in advance.
 
Big thanks to ginz and aldaman for the help. I followed aldamans instructions and she is shifting like normal now.

This is what it was reading as a problem. It's gone now though
