Tiptronic behavior - rpm drop in 2nd

[francis_a]

Not sure if this is an issue or not or simply how the Tip tranny should behave in manual override mode.

Coming from 1st and shifting into 2nd, I notice that when 2nd engages, the rpms drop by approx 200-300rpm. So when I shift to 2nd at 3000rpm, the rpms drop to say 2700rpm but then for a split second, it drops further by another 300rpm before the revs go back up again. It's almost as if power is being cut off in 2nd something similar to a Torque Management logic.

Is this normal in override mode? I do not notice the same in "D" or "S" modes.

Thanks

Mine does something a little different.

If I switch from 1st to 2nd it revs to about 4000 then hesitates for just a second, then the revs keep going. The only time it doesn't do that is if I have it in first and I just bury it. But at anything less than WOT, I get a slight hesitation at around 4000 rpm.

Hope it's normal, I get it as well. Not to long agothere was a thread on this and I could of sworn it said something about 2nd gear having a double gear of some-sort which is why the revs drop. I'm sure someone can chime in with more information on this topic.

torque converter locking up it's a good thing. and kurt that hesitation u get at around 4k is normal mine does it too it is turbo lag, until enough boost is made it will do that.

yup, normal. don't worry about it.

I had a 3.0L with Tip and swore that 2nd had some sort of synchro set up....From what I could find, no such thing....It was weird.....

Normal.

That's what I figured as well. Although sometimes I can't tell if it is the turbo or the dynamic throttle? I do baby her, and very rarely rev it up past 3500 rpm. My computer says I get 29.7 average mpg though...

^^tell me about it, the worst part is is when ur doing a second gear pull the torque converter will lock up and it'll sound like a dying cow haha. it's like WAAAAAAAAAA rrrrrrrr

i always make sure it's engaged before pushing down on the peddle. can't imagine it's too good to be in the power band really hard before it's locked up.

All - Thanks for the confirm that it's normal.

It sucks but at least now I know nothing's wrong. I love driving in Tip mode so guess just have to live with it.

Just wait till the S-tronic comes to the A4....

[AudiA4Turbo22]

^^it will be on the S4

I know, but I would rather have it on the 2.0TFSI. Imagine Quattro with S-tronic and a full GT35r turbo setup?

you can think of the TIP tranny is giving you a boost lag.
