Err, are the 5th gen auto boxes actually tiptronic? With a separate shift gate for manually engaging gears?

If it's anything like any other Honda auto box I've driven..

D1 = Will only stay in first gear
D2 = will only go between 1st and 2nd gears
D3 = Will only shift into the first 3 gears
D4 = Will use all 4 gears.

D1 and D2 for snow/slow driving/steep hills.
D3 for town driving to stop it going into 4th which could be too high.
D4 High speed and general driving.

Anyway, as Merc said, D4 floor it and it'll drop into the best gear it can.

This seems a bit strange to me lol... I've owned a tiptronic lude and by far the quickest way of overtaking is to just floor it! Drops it a gear or 2 and away ya go! All this switching to tiptop then back again just to overtake sounds daft to me lol.
But no. I shouldn't imagine you're doing anything detrimental to the box, carry on as you are if that's how you like it

If you do full-bore changes, the poor multi-plate clutches on each cog (the Honda 'box is literally an automated manual) have to take all the torque differential and they don't like it up 'em.

If you lift the throttle slightly, let it change (paddle or lever) & re-apply, the rev-matching will help soften the load.

kickdown takes care of this though yes?

I think your better off kicking down. That's how it's been designed to work. I only ever use d3/d2 if i'm going down a hill and want to use engine braking to hold my speed down. I believe that's really what the other D options are for. If you don't want full auto then I recommend using the tiptronic.
Personally I think with the control of the gas pedal is the best way to change gear (up or down). I very rarely bother with the tip. as the auto kickdown works instantly and gives all the acceleration I need for overtaking.

1) Leave it in "fully automatic" D4 and put your foot into it. It will kick down and pass.

2) Put it in tiptronic mode and "tip" it into third or second depending on your speed, to pass, then back into 4th... which is what the first option will do.

3) Manually shift it into D3 from "drive" and go back later in a rental car to pick up fragments of your transmission.

In my experience if an automatic transmission does not have a tiptronic/shifttronic gate, they generally do not like to be downshifted on the fly, especially at high speeds like overtaking another car. "Fully automatic" downshifting tends to be really harsh and jarring, regardless of the speed. I'm not saying you can't do it, but it's generally not great for them.

[edit] I meant to finish that statement but I became distracted.. if a tranny doesn't have a shiftable gate, it's not good practice to manually downshift. You can, but it is harsh and I've seen many transmissions ruined because of it. Hills and bad weather are a little different, because chances are you are going slow enough to not damage anything, however trucking along at 100km/h and dropping a gear, even in a manual is jarring, but on an auto which has less gears the ramp up in rpms is that much greater. IF a transmission has a shiftable gate it has been designed to shift on the fly...but more than likely only when the tiptronic function has been triggered... otherwise.. why would they have it? I'm not saying you will 100% ruin the transmission by going from D4 to D3, but when they designed the transmission, they gave it a tiptronic feature for a reason. I'd use it instead. Why not? It's there.

Another thing to consider; Tiptronic has lockouts on lower gears if you are going too fast to safely downshift. Will "fully auto" mode lock you out if you manually select a lower gear outside of the tiptronic gate? I've seen some cars that don't (or don't do an effective job of it) and serious damage occurs.

No. It's no good. Much as I respect your post, mostly I like your picture BlackShadow.
