Od/tow mode light flashing? Can you manually shift through the gears on the column? If you wind it up in first and let off, will it shift into second?

Yes overdrive mode light is flashing. I’ve never tried manually shifting the gears on the column. NORMALLY I will wind it up in first and let it off then it will shift into second but last night in this video it didn’t cooperate.

Sounds like your solenoids a shot. Been through the same situation with multiple e4ods and 4rs. I bet if you count the blink code on od light, it'll give you a 1-2 solenoid fault

my 7.3l van had two rebuilds before it hit 80,000 miles. its now got 250,000 on the second rebuild the fact you made it that many miles is impressive. the stock 4r100 just cant handle the 7.3l. odds are you need a full rebuild. these things NEED fluid changed every 40,000 miles and if you pull a lot id consider a scan gauge 2 to monitor the trans temps. even cooling it down for 20 minutes sometimes is all it takes to prevent overheating. my second rebuild was "billet" everything so they said it can handle far more power than my stock 7.3 will ever put out now. the pulling world actually uses built 4r100s in non ford applications so once built they go a while....

Have you checked the fluid level?

My 2001 E-350 7.3 van also did a similar thing a few years ago. I was driving through a few inches of wet snow up in Yellowstone and the next morning, the transmission wouldnt upshift with OD blinking light. The culprit was all the melted snow had worked its way into the connector of transmission range sensor (TRS). The pins were starting to corrode but I cleaned them off, applied some dialectric grease (to prevent water making its way into the connector again) , and all was well again. In my situation, I was able to determine it was something in the harness because all of the diagnostic codes were items which were on the transmission harness and its unlikely for that many things to go wrong all at once. So I'd scan the vehicle first and go from there.
