Why are all panel lights flashing, and won't go into drive

What is your question?

All instrument panel lights flash 30 times stop start again. Won't go into drive and when in neutral and drive it will only go in reverse, and moves very slowly, if at all.

What makes this problem better or worse?

Cannot drive it at all

How long has your 2004 Mitsubishi Endeavor had this problem?

It happened overnight, after driving through heavy icy slush the evening before.
