if it's a steep hill that would have you shifting to 3rd on a standard
transmission, go ahead and do it. in fact, hondas downshift for you on
hard braking. it doesn't have any detrimental effect on the transmission.

*Myself*, I would leave it in drive unless the hill is super steep,
and you need the extra engine braking to help keep from burning
up the brakes. On just everyday hills, I would leave it in drive. The
tranny will know if it needs to downshift. You really don't have to do
it yourself. Ditto for going uphill. It will downshift automatically
if
it needs to, to keep from lugging the engine. On most smaller to
medium grades at highway speeds, I would prefer to stay in OD
unless it starts lugging. Saves gas. If you drive down a hill in OD,
and switch to 3rd gear, all you are doing is burning extra gas
and adding a slight amount more engine wear due to higher rpms.
Unless you *really* need the engine braking , I don't see the point
of going to a lower gear. I'd rather stay in OD if above 35-40 mph.

I have never understood the recommendation to use engine/transmission
braking instead of the regular brakes to slow a car down. I would much
rather change brake pads than I would repair internal clutch packs in an
automatic transmission. For that matter, I would rather do brake work
than I would replace conventional clutches on manual transmission cars,
especially for front wheel drive vehicles.

Unless there is a reason why the brakes are not up to the job, I use
them to do all of my slowing down.

The only time I might manually down shift and automatic is when
traveling on roads which constantly change from uphill to downhill and
thus cause a lot of extra shifting of the transmission.

using the engine is "free" braking. using the brakes is not. once the
pads get hot, efficiency decreases, and in extreme cases, fade to almost
nothing. needless to say, you don't want that. [ask any truck driver
that's used the emergency run-off ramps on grapevine in southern
california - i drive through once or twice a month, and every time
there's a truck either in, just towed off, or the evidence of a fresh
brake failure on those ramps.]

engine braking does not consume clutch packs in the automatic any more
than any other shifting. in fact, it's less wearing than a full power
acceleration shift.

see above.

for a lightweight vehicle in ordinary use, you can get away with this
just fine. for a heavy vehicle, or a vehicle in heavy use, it's a
highly dangerous habit to be in. use engine braking and keep your
brakes cool for when you may really need them.

If engine braking is a good thing to do, then why do I see roadside
message saying "Please avoid use of engine braking" at
not-so-steep-ramp?

Thanks.
