We live just outside Cumberland Maryland and see below 0°f during our winters.
We drive SVXi every day.
With the proper sized cooler it is not a problem, but a way to help our transmissions.

What would the "proper size" be in florida?
Do I completely eliminate all fluid routing to the radiator and use ONLY the aftermarket cooler?
I dont want to overcool and I have the ecutune tcu from LAN so the temperature that the light comes on is lower than stock.
Any recommendations?
I want to stay away from putting an inline thermostat if that makes any difference.
Appreciate the suggestions.
