Transmission fluid level on dipstick

My1999 f250 2WD has a 6.0 trans cooler. When at operating temperature my trans temp (aftermarket gauge) is about 60 degrees above ambient temperature.
today it was 50 degrees outside trans temperature 110. I realize that is cooler than where the trans normal operating temp would be.
When I checked the trans fluid today at my operating temperature the level was 3/4 on the cold mark at the bottom of the stick. Picture shows stick wiped clean.
just where should my level be?

My 6.0 cooler temp runs about the same as yours.

I don't recall documenting the fluid level before it was installed, but it is now about 1/4 inch below the top of the hash mark for "full"..

assuming we both looked at it with the engine hot and idling.







Ambient temp about 100*F

Sounds about right, though at 110 I'd probably rather see mine in the lower end of the hot side.
