This year I started monitoring my tranny temperature while towing - with a scan tool. When not towing, the tranny temperature was the same as the engine, at about 195 DegF. On my first camping trip, while towing a 3500 lb pop-up camper, when it was 70 DegF outside I saw the tranny temp settle around 210 DegF, and it even peaked out at 230 DegF. I did not like that, so I put in a 24000 Lb Hayden tranny cooler. When towing with the tranny cooler temp did not exceed 160 degF. I was most impressed.
I too did have a concern about the winter performance with a tranny cooler, but the tranny shop where I got the cooler swore up & down that this would not be an issue. We will see. Happy so far.
