What is the lowest recommended temp for the 4eat tranny fluid?

I decided to plumb the aux trans oil cooler without the factory one. Summer temps are cool, but, I am concerned that with the cooler temps there will be problems. Even during the summer it took a good 20 minutes to get the tranny fluid above 100 deg F. With Fall temps it takes even longer.

Main question is, do I need to plumb back in the factory cooler to "heat" the fluid during cold weather driving?
