Changing ATF Fluid

[aaronliu]

please list all the parts (and parts #) that I need in order to change ATF fluid (transmission oil) for 2004 Cayenne S with tiptronic.

also, I need to know if Mobil ATF 3309 fluid (http://www.mobiloil.com/USA-English/MotorOil/Other_Products/Mobil_ATF_3309.aspx) works OK on my Cayenne S. it is Porsche approvals in the back of package.

Thanks in advance.

P.S. how often should I change the tranmission filter? every time I have ATF service, or certain miles?

How about I send you the factory procedure and you write it up with pictures here?

Loren, actually I am not going to do this by myself so I really don't need procedure. what I really need is the part number.

I am in Taiwan. the local Porsche dealer only accept cars that they sold for service. because my car is self-imported from U.S.,I will have this service done by a shop (not Porsche dealer)

These shop usually cost extremely high on the parts, low on the labors. so it would be cheaper if I purchase these maintenance parts from U.S., ship back to Taiwan and have them do the serivce.

So I am asking for whatever parts (number) that I need for this serivce, I will use them to order from U.S.

Thanks!!

Loren, I thought these were sealed for life units ?

According to the last Additional Maintenance schedule it is at 160,000 miles - so perhaps that is lifetime for most.

I just turned 245,000 km, should I change atf and filter at that point. I hesitate, please let me know your opinion ?

They said to me, that is recommended to change the oil and filter, than change oil again after few kilometers. And I'm at 140,000 km

I think you'll do favor to you and transmission with changing it.
