Default Ticking/"thumping" noise.

the engine is hot, trans is warmed up. Any kind of weather. I can be in any gear. but at about 2000-2300rpm SOMETIMES i hear a thump/fast rapping type noise. almost like someone put a zip-tie on my driveshaft (already checked for that haha)
for example: if i put my car in first gear (low) and drive up to 3000rpm and let off and let engine braking take place, right as it passes 2300-2000 it will make the sound and its always the same frequency, never faster, never slower, but if i hold it at 2300-2000 while in gear the sound will get louder and then quite down but not go away. but i can do this in any gear. and the sound is coming from the right side of the trans tunnel but close to the firewall/bulk head.

has anyone ever had this problem?? i think it might be the torque converter, maybe. i hope thats all it is! but i get no lost of power, no weird jerking, everything is normal but for the sound.

i think a video might be in order. But, ive never heard of the TC making noise within certain rpm, its always above certain rpm or constant.

A video is needed or simply take it to a mechanic ASAP before you cause some major damage.
