Echo OverDrive Issue

This has to be timed right. Once the light is out there is no shifting into overdrive regardless of speed. When it does go into overdrive it's just for that one time, once it drops back into 3rd that's the end of it.

I originally though this might be a temperature issue and thought once the thermostat was opening the engine was running too cool, but the thermo fan still cuts in and out as if it was getting to temperature.

It's been to several mechanics and apparently it's throwing no codes so no issue can be found.

Can anyone help me out?

This is standard behavior for the automatic transmission to help warm up the car before the blue cold light goes out.

I completely understand that.
But I still have no overdrive once the blue light goes out.
