If the transmission kicks down very hard when we go pedal to metal, is there a cure?

Some on line references suggest low fluid levels, but I don't think that condition is to be found in my car.

I don't often really boot this car, perhaps the harsh downshift is why.

Any ideas?

Worn clutches create more clearance in the clutch pack. It will need more time/fluid to lock the clutch. It will be fully locked when the ignition is already back to normal and you will feel harder shift.

Will the TCU and ECU sense the excessive time to shift, and increase line pressure to restore the proper event sequence? That possibility is suggested in the Bosch literature I have studied. I realize there are limits....

since it mostly happens after the warranty is over.

as the down-shift happens under "less than full load" as opposed to having it in D and kickdown where the downshift happens under full-load.

My tranny *kabangs* sometimes when shifting back from 5 to 4 under full load (kick-down) so when having a "lead footius attack" i put it in tip and shift back under half-load (because then the tranny shifts very smooth and fluid).

I learned to avoid shift-backs while under full load. It saves the tranny. Mine is still fine after 190.000 miles.

Why that is the very method I had adopted!

Shift early under control.

That works well in typical passing situations,etc. as I like to get the revs up early "just in case".

As I mentioned, I seldom really need to get my foot into it so deeply. And to be rewarded with a Kaa Boom then zoom,when I do, well, that is just not pleasant.

Thanks for your comment

It took a while to get used to the TIP in my old C5 A6, and almost got rid of it.
After some advice from a few techs who claimed to have driven them for years, I decided to try always driving in S and perhaps a bit on the aggresive side. It seemed to nix most of my complaints and the shifts always seemed to be firmer/faster. I hated the slushy/casual feeling of them in light throttle in D.

Was told told several times that the
firmer/quicker shifts that resulted from S and little bit firmer foot would actually benefit the tranny in the long-run as it avoided some of the "programmed slip" for comfort that the TCU has from the factory in "D".

The S8 tranny feels much more capable (Probably the programming) than the one in the A6 and Driving it in S results in some pretty crisp shifts, better than those in the A6 IIRC.

I <3 this car.
