2022 tapping near oil pan after oil change

[22 6.6gasser]

Hey I have 120k miles trucks torque converter has been progressively gotten worse with the shuttering. I believe it’s time for a rebuild. I now have heard a knocking/tapping sound that is so light and high pitch I can’t hear it on video. I changed my oil about 100 miles ago and since have heard this sound coming from the oil pan/bell housing area also heard lightly infront of the truck. Does it at idle and in neutral. Not sure if it does it in drive or under load the sound is not sequential with the engines rotation. Could this be my converter? I’ve heard lifter failure and lifter knocking in my previous 5.3 trucks and it’s not like that at all. More out of time and random. If in park and I give it a little throttle the sound gets a little louder but still not in sequence with the engine. Almost a light popping sound more than a knock. Any help would be great before I spend the money on a trans and then have to turn around and rebuild the engine.
