I agree with the ATF +3. I've used it for a couple of years now. We've had a couple of cold spells this winter where the temperature dropped to single digits (I know, that's not cold by some standards). But, with the temp around 8 or 9 degrees Fahrenheit, the car still shifted fine. Obviously, it was a little stiffer than normal for the first minute or so, but I could easily go to any gear I wanted.
