Dropped it off at the dealer. They kept it for a week. No codes found, and they claim they couldn't duplicate the problem, even though I was very specific of when the issues occur. They didn't charge me at all so I don't think they ever did anything. The edge still does it. When cruising at highway speeds up a slight incline the RPMs will go from 1500, 1800, 1500 within two seconds. If the incline is steep enough it will go from 1500, 1800, 1500, then downshift with a hard clunk. It will do this every time.
I miss real mechanics.
