I was really trying to get to the answers, and believe I just go them. This is awesome info for anyone with 970 gen 1 Panamera with PDK transmission.
Another forum member was instrumental to getting answers, and I thanked him very much and want him to know its awesome to have fellow forum members who will go an extra mile to find answers for forum members.


Here is the detail. I posted info on PDK fluid change. 2 fluids needed. Someone asked what about the clutch fluid. I was sure there was none. Someone had stated there is one.
After a bunch of searching and another member getting details, I am glad to hear that in fact, on 2010-2013 panamera, PDK has only 2 fluids to change.

Details below. It is kind of long, but if you plan to do PDK service yourself (I recommend very much to save thousands), you will want this info.


1. Porsche Panamera PDK transmission info:

• ZF is manufacturer of PDK transmission for Porsche
• They make 2 PDK transmissions - one for mid & rear engine applications, while one specifically made for the Panamera
• Here is the info dug up from ZF on this topic:
  • "In fact, two separate DCT ranges or 'platforms' have been developed by ZF, both fitted with wet clutches, for use in Porsche's various longitudinal applications. The first is for use in the mid- and rear-engine sports cars (the 911, the Cayman and the Boxster), while a completely different platform has been developed for use in the larger Panamera. For each platform, two different torque options are available, with the 500N.m versions using an 'ND2015' clutch pack, and the 780N.m versions using an 'ND2216' clutch pack, both supplied by ZF Sachs...…
    
    .....In terms of the oil circuit itself, two completely different approaches have been employed for the two platforms. The 7DT45 and 7DT70 have two oil circuits, and hence two different oils; the first is Pentosin FFL-3 for the clutch and hydraulics, and the second is ExxonMobil Mobilube PTX 75W-90 for the gear-set and bevel gear. The oil levels have been kept as low as possible, to reduce churning losses for those moving parts that are immersed in oil. Conversely, the 7DT75 has a single oil circuit and a dry sump (to minimize churning losses), with an 'active lubrication system' to feed oil to each gear-set and clutch. This version uses only the Pentosin FFL-3 lubricant, which was developed exclusively for the ZF DCTs. One of the main reasons for using a single oil circuit is that clutch cooling is required at both ends of the transmission, for the main dual-clutch module and for the hang-on clutch used in the four-wheel-drive variant. This would have presented significant sealing complications had multiple circuits been chosen."
  • What this means is that the Panamera PDK uses transmission design which uses one fluid compartment for the gearbox and the clutches, and another separate compartment for the final drive

2. MY 2010-2013 Panamera PDK transmission service details:
PDK on Porsche Panamera models 970, MY2010-2013, has 2 fluid compartments that need service. Other Porsche models employ different PDK transmission, which requires 3 compartments
To service your Panamera PDK:

• Fluids needed
  • Pentosin - FFL3 - about 9 quarts
  • Front final drive - Shell TF0951 - change quantity 0.425 liter (a bit less than half a quart)
    • I was able to cross reference this to Mobil Delvac 1 synthetic gear oil 75W-90
• Service process:
  • PDK gearbox/clutches:
    • Use FFL3 fluid
    • While car level, drain via drain plug, pour in via inspection plug, run through gears few times while PDK at 40C (may not be required), when temp reached, make sure fluid topped up to fill hole (fluid leaking out the fill hole means PDK is filled)
  • Front final drive:
    • Use Shell TF0951
    • I cross referenced to Mobil Delvac 1 synthetic gear oil 75W-90 (that is what I used in my change)
    • While car level, drain oil via drain plug, fill oil via fill plug until oil starts leaking out of the fill hole (then its full)

If you have a 4 wheel drive, you need to service the rear differential as well:

• Rear differential oil change process:
  • Use GL-5 gear oil (my cross reference to Mobil TF0951) - change quantity 1.15 liter
  • While car level, drain via drain plug, fill via fill plug until oil leaks out the fill hole (then diff is full)

Service intervals for PDK fluids - for USA market only:

• PDK transmission fluid change (FFL3) - service manual does not call for at all
  • I will do change every 60k miles (fluid only), and fluid + pan/filter change every 120k miles
    • Doing so because of info I gathered from other sites/forums, where PDK was analyzed vs used oil, not necessary to replace pan/filter after 60k miles
• Front final drive fluid change (Shell TF0951) - service manual calls for change at 120k miles
  • I will do every 60k miles
• Rear differential fluid change (GL-5 gear oil) - service manual calls for change at 120k miles
  • I will do every 60k miles
• For non USA markets, I would follow the 60k mile/100,000km schedule as service manual calls for similar intervals in non USA markets

Thank you JFP for your contribution to the information. I am sure many will find it invaluable in their quest to keep their Panameras running trouble free.
