Noise not there this morning, Questions...

As often happens in the morning, when i started the car my mystery noise was not apparent.
As car warmed up, I heard it a very little bit.
Once I put into gear, it got louder, and after I drove down my block, it was back to normal.
This suggests to me that torque converter itself is mounted properly (as was old one) since noise doesn't show up right away cold, and noise is not due to faulty installation, but some other irregularity that makes itself known once parts start moving...
I base this logic on old tranny making same noise after tens of thousands of good noise free miles.
Does rear main bearing get bathed in oil overnight, and lose some of that oil once engine starts turning? Would load from tranny induce worn bearing to start making noise.
Noise from torque converter area sounds like worn bearing, like when a bearing goes bad in a water pump, irregular hum.
