2007 tundra 5.7 transmission fail

Hi everybody, i need some help i been dealing with this truck with 245K miles and bad trans, the problem is that the transmission stop working and only makes a whining noise when is put on gear(Drive or Reverse) it sounds like when the power steering pump fails,but is not the PS pump, the noise comes near the torque converter so i thought that it was the transmission oil pump,the noise is not present when is on Park or Neutral, i did check oil level and filter and is OK witch i did replaced any way. I went to the yunk yard to get another trans ,put it on and it did the same thing so i thought again it was a bad trans so went to get a 3rd trans and hook it up and there again still the same problem with the exact noise whining and wont move the wheels at all, im lost at this point with 3 trans doing the same, don't know witch signals I need to check to see if is getting communication at all to the ECM maybe the valves are not getting power at all and that is why is forcing something on the inside,any help is very appreciated because like you know pulling this trans out and in is very hard and time consuming.THANKS
