wow...I feel vindicated. I told someone once about using "winter mode" while in 4-low and it was not taken seriously.

I just did it the other day while stopping on a very steep hill that hadn't been plowed or salted for a stop sign and then resuming with a sharp left turn....mainly because I was already in 4-low and it seemed moot to shift back to 4-high and hit winter mode too. Pulled out very smoothly with just the right amount of torque & no wheel spin.
