Everything else symptom wise, seems to be the same as you. Once it warms up really well, the noise gets much less, and pretty much goes away. I also get a whine right before shift when really cold. Right at 2000 rpm.
I dropped my trans pan twice, changed the trans filter once, and refilled 2 times with new ZF OE fluid. The sound did not change at all. That's why I have a feeling it could be something else, but the trans thing is in my mind. Other symptoms, like the LURCH, the slow reverse, went away after the fluid swaps. This though, still here.
One of these days I am going to go to a trans shop to get an opinion. For now, it seems to be working, and I drive pedal to the metal at least once a day. Seems fine. That noise is annoying though. At least its only at 2k RPM.

Same symptoms as I am having. It sounds like it is coming from underneath my feet. Torque converter makes sense, too, since it is spinning with engine speed, even in park or neutral.
Is it possible to replace the TC without touching the transmission (or is the labor about the same)? Is it even wise to replace only the TC or will that just amplify any hidden transmission issues? I found a source who will rebuild my trans and include a new TC for a reasonable price so am tempted to just bite the bullet and do both at once. However, I am conflicted about spending that kind of $ on a truck that has almost 200k on the clock. This would be an easier decision if I did not like this vehicle so much--luxurious, comfortable, tough, towing capacity, etc.
