Hi,

I just bought my first Porsche, a 2005 Cayenne S. I love this SUV on the highway but I'm concerned about the lack of smoothness in the automatic transmission around town. While I was test driving it I called up the local Porsche service center, where all the repairs/maint. on this specific SUV has been done since new, and they told me this is normal along with a slightly rough idle. They also verified this car has all the recalls and updates. My wife is calling the transmission "jumpy"... I've also had it kickdown rather hard several times after I brake lightly from about 40mph to 30mph then get lightly back on the gas. Am I just getting use to something other owners consider normal?

Another question about the locking differentials. My Cayenne has the three LED offroad lights in the center console: low, center diff lock and rear diff lock. Does this mean it has a rear diff lock? I ask because I can't seem to get the third light to come on.

Thanks for any advice or reassurance,

hi, i have a 2005 cayenne and lately i stqrted feeling that when i request for energy and the car shifts from third gear to fourth i get q moment when the trnsmission neutralizes. yesterday i felt the same from fourth to fifth. i am worried because in the porsche dealer they told me i need to change the valve assembly from the gearbox, very expensive, with no option.

can you give me your opinion?

is this a common problem in the cayenne?

thank you

To answer your question about the diff locks.....all three lights will be there.....but unless you have the offroad package.....there will be no rear diff lock.

I have a '04 CTT. Both the transfer low and front diff will "light" but i do not have the offroad package, so even though the switch goes back....it does not do anything.
