EDIT: Additional info added at bottom of tutorial, refers to recently found info, clarifying how many different fluids are needed for the 970 generation of Panamera PDK (at end of tutorial).
Attached is a DIY for changing fluid on Panamera PDK transmission.
Got this from a fellow forum member who happened to do the change. This should help many interested in doing maintenance on Panamera without paying thousands for it.
Speaking to shop/dealer, after 60k, filter/pan replacement not absolutely necessary (cost of the kit is about $350).
So for 60k, drain and refill fluid is fine. At 120k, you would do same fluid change, but this time replace the pan/filter as well.
Read the entire DIY before you start to get a good idea of requirements and estimate time involvement for you to complete.
Do not forget to replace the drain plug with its built in seal. Last thing you need is have a $15 part cause small leaking, and then have to put car up, open up drain plug, lose a bunch of expensive oil, just to put new drain plug in. So dont cut on this one part.
You can get the Pentosine FFL3 PDK fluid directly from Porsche, or from Pentosine resellers. Porsche will charge you triple the price for identical fluid. You choose.
Everything you need is mentioned in the DIY.
Since Durametric does not have capability to monitor PDK temperature yet, you can use an IR thermometer, when you heat up the PDK to 40 celsius, after you put in 6-8 quarts or so, and when doing final level check.
970 generation Panamera PDK transmission info:
- ZF is manufacturer of PDK transmission for Porsche
They make 2 PDK transmissions
- One for mid & rear engine applications (911, boxter, etc)
- Another one specifically made for the Panamera
Panamera PDK servicing requires two (2) fluids only (as compared to 3 fluids in other PDK car models at Porsche
- FFL3 fluid - Gearbox & clutches - need about 9 quarts
- Shell TF0951 - Front final drive - need about 0.4 quarts
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.
- Non Panamera models: 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.
- Panamera: 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. Two fluids total.
