I have a 2016 Ram 1500 Bighorn 5.7 V8 with about 180K on her.
Everything feels like it’s running as it always has, no shifting issues, no power issues, nothing.
But here’s the catch a good majority of the time, but not always, when I’m hovering around 35MPH or 45MPH and at that sweet spot where it hasn’t shifted gears this noise will sometimes appear for a few moments. If I let up on the gas it picks up in noise, if I power through it subsides and goes away. But it’s always at that precipice point where it’s just about to shift.
The thing is everything feels normal other than that damn noise. It started about 2 weeks ago and is only ever at those two speeds. You literally don’t feel anything when that noise is happening, and if you had the radio on even at lower volumes you wouldn’t hear it. It almost sounds like something with liquid or gas sputtering, or something electrical, or vibrating? Best actual sound I can compare it to is if you were to hold a plastic grocery bag out the window at speed and that weird noise it makes when you do that.
