I used to run a crewcab long bed 96/F350 up to 2008 after she munched her second automatic transmission.
Was using a BOSS 8' Power V
Then switched to Chevy crewcab long bed 2008/2500HD with AT and same model BOSS plow. The 08 chevy had the transmission temp option so I could monitor tranny temp during ops, The highest Id get was mid 190's 196/197 were Id let it cool.
Then in 2020 I replaced the chevy 2500HD with same model BOSS 8' V plow mounted on a Ford std cab long bed 'AT' 2020/F350 SuperDuty that comes with the transmission temp function like the Chevy did, this transmission seems to run warmer than the chevy.
This one I get buggy when the temps rise above 200°F and highest its got was 219°F with a cool down as I got paranoid.
What is the warmest a transmission 'should' run during plowing?
What is the redline temp for a F350?
Is there an accurate way to check my trucks temp gauge for accuracy?
Itd be a sad day to find out my truck is reading 5° cooler that its really operating at.

I think, it might be your plowing style?

aux transmission cooler?

200-220 is quite normal for a 2020 f350 10 speed. At 265, the PCM will go into default modes, to cool it down.

So far most the snow this year has been the hard stuff, we had rain back in December turning our hardpack to ice.
Right now in town there is only the airport runway that is bare pavement, veverything else has about a 1" to 1.5" of hard pack

So I might be ok as long as I have short stints in the low two hundred teens?
210 to 216°F?

Does this truck have the heavy duty trans cooler??

You might want to think about changing the transmission fluid more often than recommended.

Can he use OEM plow fluid in place of the transmission fluid for best performance?

Ya know, in a pinch it would probably work.

What if your OEM plow fluid all ready is ATF?

I remember the old Boss Power V manual specified Dexron 3 in the powerpack.
I will have to check the new manual.
As far as I know this truck had the Ford plow truck package w cooler and HD front springs.
All my plowing experence has been in arctic NW Alaska conditions (Kotzebue).
We get quite the range of types of snow, the worst is wind-drift.
If drifted at extremely cold temps the drifts can be really hard (boot tread only markings) tempered snow, some that snow can sound like broken dinner plates as its moved.
Some the really hard stuff we have to hire a payloader to remove it as impossible to plow it w F350.
