Tranny Noise
Ok, I am stumped. My 01 V10 4x4 Auto has developed a strang noise. At low rpms, there is a small grinding or rumbling noise coming from under the truck. At first I thought it might be a wheel bearing, but I do not hear the noise when I move the truck in neutral, only when it is in gear. It sounds like a bearing, but I do not know. The truck has 75000 miles and zero trouble.

The 4R100 may be due a rebuild
There are many new upgraded parts
Usually a rebuilt 4R100 is much better then the factory one.
Make sure you transfer case is really in 2 wheel mode and your front hubs are disengaged to eliminate the 4x4 system as a noise source

The noise is not there when I put the truck in neutral and let is roll. It is electronic engagement for 4x4, so the hubs are automatic. If I turn them to manual, they will be engaged.

I agree with Fred. These factory automatic transmissions usually only last about 75 - 100k, depending on service and use.
Usually the torque converter is the first to go. But with that many miles you might as well spring for the rebuild. A new torque converter would be included in a full rebuild.
A properly rebuilt transmission will be stronger and last a lot longer. Check out the Automatic Transmission Rebuilders Association (ATRA) website. They will be able to locate a certified local transmission rebuilder. I use one of their local members shops when I had my f150-4r70w rebuilt several years ago and was amazed at the quality of the rebuild. It only cost me $1400, which was at the low end of what I researched it would cost. The 4r100 will probably be a little more. Make sure you ask for a heavy duty clutch pack, heavy duty torque converter, and a shift kit. They should automatically include any other updates in the rebuild.
