Bearing-like Noise that has caused me to change transmission 3 times
2005 F-150 LARIAT TRINTON 5,4L V8 Automatic 4x4: I have this noise that sounds like a really bad bearing sound that hasn’t been able to be detected by over 5 mechanics and has caused us to dismantle 3 fresh transmissions without success - Sound occurs first starting after 7 minutes, reduces while driving. I can upload the sound recording if i have an avenue to. I really need your help as i have spent thousands of $USD to no avail! Thanks a million guys!

Need more info:
Manual or Automatic transmission?
Does it make the sound sitting parked with engine running?
If you have the engine running but in neutral and drifting downhill is the sound still there?
Does the pitch of the sound change under varied conditions?

Thanks Charlie , it's an auto transmission, sound begins after 5 minutes of cold-start, reduces during driving ,disappears after 15minutes of driving, even when parked with engine running; the pitch doesn't increase at any time.
