I don't mess with mine.
I see you have auto transmission. Make sure to lock-out O/D til about 50-55 mph when it is slick. If your transmission shifts as firm as even my stocker did going into O/D, it won't think twice to attempt to spin you around. Mine would try when I was bone stock as well.
What I do is, wait til 50+ to engage O/D. When you feel it start to shift (and definantly before the TCC is locked), just slightly ease out of the throttle. After is locks up, gently roll back into it. Won't shift as firm. Has worked every time I've done it. Once I figured it out anyways. Scared the crap out of me the first time on a slock road.
