I have a 2021 custom trail boss with a 6.2 L and the 10 speed transmission. Almost every time after I get up up to speed, when I slow down to about 15 miles an hour there is a rattle coming from underneath. I took it to the dealer, drove around with them they didn't know what it was. Then they replaced something to do with the torque converter(don't remember what specifically). When I got a back it was still making the same noise. About a week later my transmission completely went out. I just got it back after they replaced the transmission and it is still the same noise. After all that, the tech that worked on it said he had one and it is a normal noise. Has anyone had similar issue? If so did you get an answer?
