The maximum proper speed is 39 at half throttle on a flat road, but the
maximum speed is 96 or where ever the rev limiter ends. The proper
speed is based on engine lugging, or throttle position. The proper speed
is programmed by the automaker. If you asked them, they would say
the proper speed for 3rd gear is 35-96 based on throttle position.

D1 is mainly used for slippery conditions such as snow, ice at low-speed.
Descending on D1 could be damaging to the transmission when
up-shifting, and the chance of over-reving is high.

I don't doubt that 39 is the optimal shift point set by Honda
engineers for certain conditions, but forcing it to into a higher than
optimum rpm (within reason) won't hurt anything. For example, in
descending a long grade, if third gear keeps the speed at a safe 45 or
even 50 then that is the gear that should be used.

D1 could be damaging on upshift? I don't think that makes sense. If
you mean that it could be damaging to downshift into first at too high
a speed, that is theoretically true but I don't think the AT will
actually allow that to happen. Descending in D1 (if that option is
even available) would be for extreme grades. If the hill is so steep
that it would over-rev in D1, you may have to use the brakes to keep
the speed *very* low, like 5 mph. Better yet; find another road.
