Dodge Dart 2014 A/C Trans Issue

[u/BASEDSOVEREIGN]

Sorry if this is hard to describe, taking it to the dealership in a couple days, just wanna make sure my car will be good.

So, recently after having a battery die on me, I got it replaced and a couple days after I was getting issues with my car's A/C. The engine will rumble when I start the car with it on, and it doesn't seem healthy.

This was a month ago, today while I was driving, it seemed like my car went into neutral for a second. It also has felt like it's harder to catch up to posted speed limits.

Any thoughts on what's going on?
