The codes that you are getting are related to the valve body in the transmission and sensors mounted on it. For example G182 means there is an issue with the transmission input speed sensor. It is mounted on top of the valve body.

Because there are several transmission related codes, the issue could be the valve body but it may also be wire harness. There is a 16 pin plug that connects to the valve body. It may have leaked oil. Or there is a short somewhere. 

The other possibility is that the transmisson control module or TCM. If it got any water damage it will act up.

Since the car is at the dealer, they should be able to narrow down the problem. I do not think the problem that you are experincing now has anything to do with the air filter replacement.
