I'm honestly getting frustrated with my car and could really use some advice.

I have a 2013 Dodge Dart 1.4 Turbo with around 80,000 miles. Recently I've been getting transmission issues and a "Service Transmission" message. I took it to a transmission shop, but they told me to take it to Dodge because they weren't able to help much with it.

The codes that have come up are P1C9D (Gear Shift Position Sensor 2 Circuit) and P0893 (Multiple Gears Engaged). The car still drives, but the transmission warning keeps coming back, and I have no idea if this is something simple like a sensor or wiring issue, or if the transmission itself is starting to fail.

I'm a college student, so I'm trying to figure out what I'm dealing with before I spend a bunch of money chasing the problem. Has anyone had these codes on a Dodge Dart before? What was the actual issue, and how much did it end up costing to fix?

At this point I'm just looking for any advice or personal experiences because this has become really stressful.
