Panamera Transmission pan leak

2010 Panamera 4S, PDK, 44,xxx miles. Found oil on transmission pan. Cleaned thoroughly and drove about 100 miles. Oil appears to be seeping where the pan meets the transmission. No dripping but wet. I understand this entire pan needs to be replaced every 120K which is a long ways away.. Is there a way to reseal the pan or is entire replacement necessary? Also I see several pan options... OEM, VAIO and Beck Arnley. Quite a difference in price $139 to $400ish. Are they all of similar quality? Also can the pan just be replaced or will it require a complete fluid change?

Thank you!
Steve

Hey man, glad you posted this as I have a bit of knowledge on this and I got you covered on all the info you'll ever need right here amongst the other members on here. 1) Vaico is the OEM brand for the filter/pan/gasket kit. 2) You will need to replace the entire setup and the Vaico kit comes with the entire assembly (minus pan bolts) 3) You will also need to replace the PDK fluid as well.

In your case, a leak like that is pretty premature and with that said, I wouldnt risk trying to use the old pan as it is plastic and most likely is warped beyond the point of sealing. You'll want to do a fluid change as well since your pretty close to the 60k mark for fluid servicing anyways. With the PDK fluid, I would take this opportunity to switch out to a full synthetic fluid by Motul DCTF. Its porsche approved and works much better than the OEM fluid. The shifts are a bit snappier and the gears get way better protection... also, it is cheaper than OEM fluid too.

Thank you! Couple questions. Do the bolts need to be replaced? Am guessing there is no torque issue like some high stress fasteners however is there a sealing issue? Have you heard anything about Beck Arnley pans? I understand they have been around along time and are not cheap Chinese parts, but don't want to have to do it twice!

In your case, I would change out the bolts too... The sealing issue can be a combination of bad fasteners, warpage, and bad gasket. You are fine with a Beck Arnley, however, as a safe guard, I would also apply a thin film of high temp silicone sealant and there's a specific one to use specifically for your application used by Porsche... let me go grab mine and link you to the part number.... brb.

For Sure, post here when you get all the stuff in. Theres a specific procedure to do to prime the fluid back into all the solenoids as well and i'll get that to ya when you cross that bridge.

Received transmission fluid today. Ordered from Pelican Parts (whom I have done a lot of business with and have a high regard for) but was shipped Febi Bilstein 39070 Gear oil. When I ordered It was listed as Pentosin FFL3, and there was a note referencing Febi Bilstein see below:

Item Name
Dual Clutch (PDK) Transmission Fluid - Pentosin FFL 3 (1 Liter)(2010 Porsche Panamera 4S Hatchback)(m)
Part #: 000-043-305-13-M36

I assumed it was the Pentosin with a Febi label but it appears to be a different oil entirely. Is this OK to put in my Panamera PDK or should I get actual Pentosin FFL 3?

Thanks

That part number you got was right and wrong.... Its actually refering to the seperate gear oil for the front differential tied in with the PDK transmission. I actually do not recommend this gear oil even for the front and rear differentials. I highly recommend using the Motul DCTF as not only is it far superior to the Pentossin in protection, performance, and long time proven record, but it actually improves the function of the PDK transmission. Its also Porsche Approved and get this... is much cheaper than Pentossin..... I also recommend matching it up with 2L of the Motul 75w-90 gear oil for the front and rear differentials. The car runs much quieter and smoother. Amazon is the best place to get it...

Okay, I see now. So it definitely is not a substitute to for Pentosin FFL 3 or Motul DCTF in the Transmission ... . Basically Pelican Parts is listing it as a substitute for the Pentosin FFL 3 for the transmission oil when it really is only suitable for the front and rear diff oil.. Geez that could have been ugly!!

A quick follow up to my last post. I contacted Pelican Parts. The part number listed above (000-043-305-13) is the correct part number for the PDK transmission fluid and in fact they list and sell the Motul DCTF under the same part number but with a suffix of M1399 rather than M36 the suffix of which which designates the manufacturer of the fluid. The Gear Oil for the front and rear dif is actually part number 000-043-205-30 and there are various suffixes for the different brands of gear oil as well. Wanted to make that clear so as not to cast any negative aspersions on Pelican Parts they are really great to work with.
