...I'm going to suggest that your system ground is corroded....to the point where the sensors aren't finding proper ground...undo the bolt that holds the main black 1/0 cable to the chassis ground...wirebrush that lug free of corrosion 'till shiny...then the chassis too....so a steady 300 or more cold cranking amps can get thru there~ You just need good ground connections to the frame and dashboard components, fuel pump, ignition system and the headlights and dash components~....when in doubt TEST for 12.5 or so volts....the GROUND has to be there or the sensors will not be reading correctly~

sounds like a trans issue... not sure if the TCC Silenoid is internal but im sure it is also check the fluid while it was hot and running make sure it is full. I would have it check out soon.. as the longer you wait for work on a trans the more damage it will cause and that = more $... hope this helps
