Mark,

I can only tell you from my experience. I did this once - right after having
the engine reinstalled. Things weren't running right but I had to get the
bus home - so my 280+ mile trip from Grand Rapids, MI to Port Huron, MI was
done having to put the bus in neutral and turn the key off and on every few
minutes (to reset the ECU). All was going well until about halfway through
the trip I accidentaly put it in Reverse. Scary - fish tailing tires
screeching - etc. Good news is I reacted quickly and got it into neutral and
welll over a year later I have seen no adverse effects.

That all being said I can also say it's obviously not a good idea.
