Was driving on the highway with PSM off, put the pedal to the medal to get by the slow-poke messing up the flow of traffic in the left lane, tranny down shifted to 4th smoothly, and then when it was revving high and tried to up-shift it slipped/stuttered and I had to hit the tiptronic on the steering wheel to make it go to 5th. What is going on???

Yes, my tranny fluid is at the level it is supposed to be, and no I did not have the floorshifter in manual (in case you were going to ask).

 

Hey Bobby,
I had a simliar issue with my wifes past V6. We took it to a dealership a few times and they said it was a known issue. The flashed our ECU twice and replaced the tranny mounts. Not sure what was the actual problem as we just traded it in over a week ago for the Turbo. Ours happened on 5th to 4th gear down shifts....
Hopefully this is helpful. Good luck!

 

Droped off the car at the rude stealer today- they had to order a new speed sensor harness. Hopefully they will get it in tomorrow, which is when they think it will arrive. Till then they have me in a 2006 CS loaner,

 

How bout a power comparison with the v8?? How noticeable?

 

It's a real difference! the CS really moves off the line much faster, and when I floored it at 60mph or above it was like a rocket.
My V6 moves much better since I did the Fabspeed cat bypass and moved to a BMC filter, but not this good.
