Shudder/rumble.

[Mblackburn1013]

I’ll explain this the best I can, I’ve read to many things it can be. But I have 2015 Silverado, 5.3 . 6L80  transmission. Ok when on hwy speeds at 45-65. It makes like a rumble sound. Not all the time either. And it’s like at certain points in the road. So I can almost say to myself it’s about to do it. But I like I said it’s not all the time. I can go days sometimes. Also I did rebalance my tires and went away for a couple weeks, Of course came back. I’m new to all this so please help
