my understanding (after lots of digging and reading) is there are 2 fluids that need replaced, the first is the clutch oil which is separate from the gear oil, it should be replaced twice as often as the gear oil (60k and 120k) and can't be done by a DIY method as the cooling pump needs to be turned off.
The gear oil as I understand is very straight forward - as simple as changing your average tranny.

the filter is built into the pan and is for the clutch oil, would probably be a good idea to change it at 120k along with the clutch and gear, but that again brings up the problem of a DIY clutch oil change.

Does this sound about right?

 

I was not aware of need to change clutch fluid and PDK fluid to complete transmission fluid service. I have been looking through the service manual and did not come across any references to changing clutch fluid (I will go sometime soon to read thoroughly through transmission/PDK section).

Yes, manual calls for replacement of PDK fluid every 60,000 miles or 4 years.
Yes, manual calls for replacing PDK filter/pan every 120,000 miles (language used kind of makes it sound as though replacing sooner is not a bad idea, but they do state 120,000 miles interval).

PDK transmission fluid change is done DIY while fluid temp is at 40C.




If anyone knows more precisely, please chime in. It will be very useful for all members.
Thank you.

 

The transmission in the Panamera only has one type of fluid to change. I know the 911 PDK's have separate clutch and gear oil compartments. Much of the info I found was talking about those vehicles. The Panamera uses the same oil for both clutch and gear sections.

This is supported by procedure/info from the factory service manual.

I posted a DIY for the job that might be helpful.

yap after some digging I found this " The second PDK variant, the 7DT-75,[44] is available on the 2009 Panamera and 2014 Macan.[3]
[44]
[48]
[87] This is constructed fundamentally differently from the 7DT-45/7DT-70 versions; in that the internal shafts are mounted above the input shaft, so as to achieve a lower centre of gravity for the Panamera and Macan.[44] It also uses just one oil circuit,[44] whereas the 7DT-45/7DT-70 use two separate circuits;[44] with very different specifications of fluids needed.[44] "

seems it is a single circuit - makes me think the filter change might be a good(if expensive) idea

 

Based on oil analysis I posted today ... I see no burning reason to change filter 60K. I plan to change at 120K as suggested.

 

Most places say you can change the filter at 120k miles. At 60k, drain the oil and fill.
Those in between, I would suggest they crawl under there and check the fluid level (there is an inspection plug that can be accessed on side of the transmission).
Thanks for the info.

 

good info
