2018 hd Ram 2500 slt 6.4 weird metal noise

[Lb30]

I have been having an issue, with a weird metal to metal sound. Only seems to happen while slowly, accelerating between 20 to 32 mph. Not sure exactly where it’s coming from, but it seems to only occur when I feel a small shudder from under the truck almost like the transmission or torque converter not sure which. Any ideas?

Finally figured out the noise, I raised the rear end off the ground, put it in gear and hit the accelerator when it shifted is when I heard the metal sounds coming from the transmission
