Re: What to expect at -16 (-55 windchill)

Mine was staying in 6th and 7th when it was 0 F out after an hour of highway driving.
If I recall correctly the Transmission was to only 150 or so.
I wonder sometimes if the Towing Transmission Cooler keeps my transmission too cool when it's frigid out.
Since the new Rev C update I did try a short highway trip and transmission I think was only 140 and it shifted into 7th and 8th fine. But that was not a full test. I'd have to make the same trip at the same temp to be 100% sure it's "fixed".
If you are having Cold Shift problems get the Rev C or greater update on the V6 Transmission. It specifically states improved cold shifting.
