Transmission Noise problems of the 2015 Mazda MAZDA3

Transmission replaced at 100000 because of bearing in the transmission. Now transmission making the same noise of 111,000 miles after being replaced. Mazda was purchased at paul miller Mazda lexington kentucky. Transmission problem became noticeable while in motion it starts with a low noise and the air is the bearing gets used more and more from day to day uses he gets louder and louder specially at lower speeds from 10 to 60 miles an hour it's quite noticeable stops when the vehicle stops. Was informed by paul miller Mazda this was the only second issue they've had with transmissions and it was not a route fix without replacing the transmission. I purchased extended warranty at purchase of the Mazda and it's a good thing I did because now I'm on my second transmission with a 2015 Mazda with 111,000 miles and it's already been through two transmissions one at 101,000 and now again at 111000 less than 9000 miles after the replacement. Transmission wasn't a new tthat was put in the 2015 Mazda, it was a transmission which I was told had only 8000 miles by paul miller Mazda and millennium insurance.
