Ill check out all the wiring with more detail, and the 15 minute thing I'm not sure, once the truck is warmed up about 15 min later O/D off and shortly after trans temp.

Disconnect the battery terminals, touch them together then hook back up. This will clear any codes and the pcm will relearn the sensors.

Then you need to find why it's reading high.

Hello. I have a 2001 Dodge Ram 1500. Something similar is happening with my Truck. Around town it drives fine. But driving it on the Highway about 20 minutes out the Trans Temp light comes, THEN the O/D off light. Took it to a shop to have it serviced, they said they fixed it but apparently not, because it still does it. And the last time I drove it it feels like the transmission is acting up. Does not drive as smooth as it did. And I don't know jack squat about Automobiles, so have not clue what people are talking about. I have no idea what to do. Any suggestions.

Usually, that's due to either low fluid, which would give you other odd symptoms as well.... or the check valve in the trans cooler line clogging up. Or, possibly a failing trans temp sensor....... So, check fluid first, trans fully warmed up, idling, in Neutral. (block the wheels please, so it doesn't roll away.....), if that's good, go after the check valve next. It's in the cooler line that goes to the bottom fitting of the radiator, right where the metal line from the trans, transitions to the rubber flex line. There are a couple threads in the FAQ/DIY section for options on how to deal with it.

Wondering if OP found the solution. My truck does the EXACT same thing.

Thank you!

It could also possibly be the trans cooler if one is equipped. Mine was clogged. Usually after a rebuild it needs to be replaced. They sometimes clog either way. Seems these transmission run high to begin with. Temps of over 200 degrees are common. I cut out my trans cooler, replaced it with a bigger aftermarket cooler.
