That is the perfect example of the limitations of the 'Selectrac' full
time, it's one wheel drive only. With Commandtrac, you at least can get
one front and one rear wheel going due to the center lockup and with
some practice, you can get all 4 spinning or at least both rears and one
front.

You hit the brake pedal to load up the spinning tire and the friction
will equal the torque needed to break the other side free so both wheels
on the same axle will spin. The owners manual mentions using the
E-brake to do this, but I find a fast hit with the brake pedal works
pretty well.

This is an old trick with open diffs and goes way back.

The shift on the fly feature works really well in both of our Jeeps. I
live in Canada and just treat 4 hi like any other shift. When I see
snow on the road I shift in, when it clears, I shift out. I also find 2
better at snow or slush covered intersection corners. I shift back to
4x4 as I straighten out.

Running in 2 high is usually best for mileage.
