What should the temperature on the front transmission cooler be

Just to add onto what MGD said above, if you want to lower your trans temp, removing the thermostatic valve is a good way to do so.

When your trans temps get hotter than your coolant temp you have a problem....
It's funny I never worried about the temps before I got a programmer. ..the FX4 just had the one coolant Guage and all was good lol.

Oh boy.
Coolers - the good ones- are 'stacked plate' designs. That is, there are (in this example) 10 parallel paths fer the fluid to pass. Avoid the single-path coolers like the plague - they are restrictive and useless.
Want a good cooler? - look at Derale's active stacked plate units.
A 4R70/75 trans has a design optimum operating temperature of 170 degrees. That spec is published everywhere. The trans also has an external thermostatic valve block that limits flow to the front cooler around that temp.
IF you have such a trans and you are operating north of 200 degrees for ANY length of time, change fluid often, as Mercon V degrades as temps climb towards 200.

Lastly - fer clarity: If running an Edge generic canned tune, all you can adjust are a handful of User Settings. Hence, you are still running a generic canned tune with some custom settings - NOT a custom tune. You have no access to the ~300 parameters that a true custom calibration can potentially alter. Apples to oranges.

I did find that Ford has different "tow package" options. In another thread related to this topic, a member stated he has the 4.6 V8 in his 2004, but his transmission cooler is the "heavy duty" 10 plate. Mine is only 4 plate.
As to removing the thermostatic valve, I'll leave that intact, and continue with the 10 plate install.

Scary method described for doing a "home" transmission flush in that link...

I agree. Running it dry all at once IS scary, lol. - I prefer using Mark Kovalski's method (he's the feller whut designed these trannies):

That TCCOA link was intended to supply some info / specs fer the trans and fluid.
Some folks back in the day were installing 13+ row Super-Duty coolers in their Lightnings (some disassembly required, lol).

The main reason I advocate active cooling is, a passive cooler does not function well with no airflow - as in stuck in traffic/stop&go, climbing a steep grade slowly or backing up a long path with tow load attached. It also sheds heat more slowly.. Having an efan, as you do, helps some (especially if you have a manual in-cab override that you can turn on as needed).
