Tiptronic

[GD]

Has anyone owned a tiptronic on both the 996 and 997.

If so, has anyone noticed that the gearbox takes longer to engage on the 997 when moving from neutral?

If I'm in traffic on a slight incline, I normally push it into D and immediately press the gas.

In the 997 the car slightly rolls back before engaging and is quite annoying.

I thought the tiptronic boxes were the same, but this is definitely slower to engage from neutral into drive.

:dont know:

Do you have your foot on the brake when selecting 'D'. :?:

You are supposed to.

Why are you selecting 'D' when in traffic and on an incline :?:

If I'm on a incline in traffic, I have my foot on the brake and the gearstick in 'D'

At this point the car is in 1st gear (as it's on an incline) rather than the usual 2nd gear, I release the brake pedal and the car maintains position until I press the accelerator, not aware of any roll back?

Yes I move the gear stick with brake depressed and it will only go into 1 if the car is cold, otherwise it selects 2 by default.

So if car is on slight incline:

Car in neutral (stationary traffic)
Foot on brake
Select drive
Foot off brake and onto accelerator (quickly, to avoid using handbrake)

If I do this quickly, the car rolls back and the gear doesn't engage for about 0.5 seconds. It's definitely different/slower to my previous 996.

Thanks.

I know some driving instructor will disagree but then im a Army vehicle intructor and we have Tipmatic gearboxes in our trucks and i teach the same, but just keep it in D with foot on brake.
I never shift into N unless its a motorway jam and im there for longer than a min or so. Traffic lights etc, hold it on the brake.
The Tipmatic i mentioned before is actually a close PDK type gearbox where it has a clutch but with servos to change the gear. So when its in gear, foot off brake it wont roll forward unlike sometimes Tiptronic as revs in the Tipmatic will "engage" the clutch. If i remember rightly both gearboxes are made by ZF.

With foot on brake and selecting drive, you shouldn't need to rush to get to the accelerator to prevent from rolling back. Does sound like slow engagement.
Have you checked your AT fluid.

Are you sure it's an engagement issue. Maybe engine idling too slow.

Not sure why you'd put it in N. But when in D mine doesn't roll back, irrespective of how long the foot takes to move from the brake to the accelerator.

I've never put it in N for any of the semi- auto boxes I've had when in he car. But out of curiosity my PDK car does take a tad longer to move from N to D than the BMW DCT. But it makes no practical difference as I always keep it in D.

The wife has an Audi dual clutch and that has a ridiculously long transition from D to R, and the loss of coupling moving between the two can catch you out on a hill unless you have your foot on the brake.
