My tip goes into 5th gear so early
If not manually shifting, I hit 5th gear by 40mph+. Is there a way to prevent this besides shifting manually?
Thanks,

Nothing.
The trans is not governed, it is electronic.
To the OP, there is nothing you can do other than get on it a bunch and let the computer learn your driving style.
This will only last for a short period, then driving like a grandma will put you back in short shift mode for MPGs.

Once in a great while I would mimic this behavior in my manual equipped cars using very little throttle once the car moving and then upshift but continue to keep the engine speed low, down around 1200 rpms or so.
At some point the car's moving maybe 45mph and the tranny's in 6th gear. (This in my 6.0l V8 GTO with 6-speed.) I have not done this that I can recall in my Turbo. I have done it with my Boxster but it does not have the torque and my very sensitive right foot refuses to lug the engine and more gas pedal travel is used.
Sincerely,
Macster.

I only use the auto setting 5% of the time, mostly combined with the cruise control on a long highway drive, (and shhhh... mostly when I'm drinking coffee).
As far as I gather, the shift points were driven by avg fuel economy claims by Porsche. You can alter the mapping but it is lost upon shut down. A few WFO runs and you'll see the shift points alter a bit higher - but not that much higher. You may see 55mph before the 5th gear shift point - not much of a difference really.

One thing I do love on the tip is the ability to kick down by just rapidly squeezing and immediately releasing the throttle. This will drop you down to the absolutely lowest gear available near instantly, would be 5th to 2nd in your stated range, and you can then slide the shift lever over to hold that gear.
Also works while braking
I too haven't driven in auto mode much on surface streets or back roads, really only highways

This is my biggest complaint about the Tiptronic. The shifting in the Auto mode just runs thru the gears and before you know it you are running around town going 35mph in 5th gear at about 1200RPM. I usually let it go into 3rd or 4th gear and then switch to Manual mode, which will keep it in 3rd or 4th without going into 5th gear. Then at a stop, I switch it back into auto mode and do it all over again. I asked everybody and anybody if there was a way to modify that by reprogramming and the answer was a resounding "NO!"

From Adrian's book:
- There are also differences between the Chrysler and ZF made tip's. The 3.4 turbo's and all 3.6's have Chrysler built units with the ZF unit being lighter by 30lbs.
- The TCU unit (in the backseat for the most part) was made by Siemens.
- The Chrysler unit runs hotter then the ZF.
- 2 reverse gears for the Chrysler.
- Gear kick down before corner works from brakelight signal to ECU.
- Steering input data to TCU - TCU decides if gearbox up/down shifts can take place if normal shift program point is reached ie, in the middle of a sharp bend trans unit stays in gear without shifting.
- Gearbox cannot be shifted to P setting past 6mph. (Not willing to test this out!)
There is so much more to these auto units that make them one of the best units on the market.
The new 977 units are a world way higher then the tip as well.
