Hey Ken, not long after your visit I posed the following question to him:
"You have a coach sitting, stopped, at the top of a steep hill.
You put said coach into Super or Low (ie, not Drive) and coast
down the hill, WITHOUT changing gear at all while moving. Is this still bad?"
His response (to paraphrase) was "yes, it's bad. The tranny will TRY to
hold back the coach, but it's too heavy. Use your brakes, that's what they're for."
I think that is consistent with your understanding of the bands, and I don't think I'm misquoting.
