Hi. Sorry, I didn't see these notifications until now. Yes, our issue was the transmission as well and we had to get a new one put it. Our dealership ended up finding us a used one out of a wrecked car and it cost us half the price of a new one. No warranty covered our repairs as we were outside of all the warranty periods with over 100,000 miles at the time. They also told us the transmission is sealed and they don't work on them, they only replace them. I'm glad they are covering it under warranty for you. I would have never guessed that sound would be coming from a transmission. Good luck!
