Arrow High trans temps in cold?

So lately it's been cold here, between 10 and 30 degrees ambient. I thought trans temps should average around 100 degrees over ambient, right? I've been noticing lately higher than normal temps when it's cold outside. Today it was between 10 and 20 degrees on my commute - mostly highway speeds - and my trans temp was showing 150-170. I just had both filters changed w/ OEM filters and the fluid replaced. This is normal, not aggressive driving. What's strange though is that when it's warmer outside, the temp seems to stay within "normal" range.

Any input is appreciated.

well there is a thermostat inside the pump that opens to flow fluid to the cooler around 180 degrees. 150 is normal for me all the time. did it start doing it right after the filter change?

Ok, that's good to know. I installed my edge monitor at the same time as the filter change, so I don't know for sure if it was doing it before or not. I'll keep an eye on it, but I remember in my old truck the trans temps would be lower in colder temps.

my trans is always between 151 and 158 unloaded. Doesn't matter if its 0*F or 90*F. thats normal operating temp for me. It's usually between 160-170 while towing, i've never seen my tranny get above 178*.

just installed my gauges and Ive been getting between 150 and 180. i think my sender might be messed up though because i tightened the wrong hex head on the fitting and spun the sender inside the housing
