So i did some tap tapping underneath the truck. When I smack the exhaust I can hear a rattling from the second cat (circled in red). So good news as it's not engine or trans, just some bad exhaust.

I haven't had a chance to check the fluid. I did have it serviced last August, they said everything looked normal, clunk is normal, typical dealer bs. It still has an extended warranty, so I'm not inclined to mess with it until it gets bad. If there was an easy way to check the fluid I would, but since gm removed the trans dipstick, harder to do that imo. I will say the sound is most noticeable under load. If I coast, I can't hear it, only when I get in the gas do I hear it.

Seems to drive fine, just makes that noise. Doesn't over heat, shifts fine. I think it increases with revs, but the motor gets too loud and drown it out to be able to accurately tell.

Hey all. 2015 gmc sierra 1500 slt with 6.2 and 8 speed w/126k miles The other day i noticed this odd metallic rattling sound coming from where the engine meets the transmission, that general area. I cant say for certain that it increases with revs, hard to tell from the cab. Sometimes it's there right on startup, other times not. Here is a youtube video of it https://youtu.be/K_kR47dC5PE?si=LPfcTWPIm7XwrZlH

What grill insert is that? i like how clean it looks.

Has anyone installed a set of the Go Rhino RB20s? was looking at these as a more minimalist approach and tossing the drop step onto the passenger side for the GF. Thanks.

IMO get a custom driveshaft made. It will be a much more reliable and better install.

Here's mine. All stock, and will stay that way for the most part as ill focus on modding my other vehicle. Parked next to each other, the other is a 2008 H3 Alpha (has the 5.3), and yes I wheel it lol
