I found a YouTube video on how to do it myself. If I wasn't getting my driveline looked at i would've tried it myself. If this fixes the problem and it starts up again. I'll just adjust it myself. Looks like I could do it in prob a hr or even less.

2019 pete x15 performance 2350. 565 hp 1850 tq eaton 18sd 120k miles. I've seen a few posts with what sounds like a similar concern I'm having. I can feel what seems like something hitting the floor of my truck in higher gear/speeds. Starting around 6th gear. Hear it most in my 7 high or 8 low and high. Sounds like every rotation. I can hear it and feel it. Slight vibration at my feet with it as well when pulling heavy loads up hills. My wife can't hear it when she's in the sleeper. In other posts some suggested getting the driveline balanced. Is it possible the clutch needs to be adjusted? I've had a mechanic i trust go under and look at the drive lines and they said everything looked good. Its been doing this the last 40k miles or so

Gentlemen, look closer at engine. Fuel pump timing, junk pump, gear train, cam. Those vibrations get felt right to the floorboard. Especially during hard pull. 1400-1600 rpm on x15 performance. Sounds like a helicopter smack. Especially evident when giving the engine hell going up mountains..

lots of complaints and bulletins with little fixes

I got one of those too..
