Hi guys. I have a 2024 2500 6.6L gasser with the 10 speed now with 6k miles on the odometer. On cold start up (e.g. before heading to work in the morning, or in the afternoon on the way home), I get what I think is belt squeal. It lasts for 15-20 seconds, and it sounds much worse when I put it in R or D with my foot on the brake. (The cab is so well insulated, I have to open my door or roll down the window to hear it.) I’ve had it to the dealer twice. First time they said they couldn’t replicate the problem, which was ridiculous because it did it when I picked it up. The second time they replaced the belt and idler pulley, but the problem persists. I’m thinking perhaps something about the belt and pulleys is not aligned correctly?? Or could it be something internal to the transmission?? Has anyone successfully solved this problem? Here are a couple of vids. You can hear it really start when I drop it into R and then disappear 10-15 seconds later. https://youtube.com/shorts/0HFmp5OGIPM?si=YbCZewrJhMgLuFFx https://youtube.com/shorts/QbSJIw1oYBo?si=DIqD6jAhsdh7QZ3q Thanks!

I too have the belt squeal -- on cold start up before and after work. Dealer replaced the belt and idler pulley but it is still squealing. I'm trying to figure out what is causing this.

Someone may have mentioned it already but Borla makes one. I believe the part number is 140833BC. Borla S-Type model. Check out Borlas website to confirm.
