300 miles on C4S noticed small drops of oil on garage floor. Dealer diagnosed transmission oil cooler as the problem. Seems a strange premature failure or defect. Any 992 owners with similar issue?

it might not bee anything but here goes. 20 years ago I bought a Buell motorcycle, powered with a Harley Davidson Sportster engine.. Parking it in my garage, the front cylinder was dripping oil on the garage floor ! ! I gasped HARLEY Davidson ! ! !! 20 years later, that was the only oil that ever leaked out of that engine ! ! ! I have no clue..... jp

The final diagnosis is transmission oil cooler relief valve failed. See photo. One major issue we dealt with is the gear oil spec. First the oil was not specified for the 992 8 speed box. Porsche tech services provide Mobil 1 FS 75W-80. It is not available in the US. After a few days it was decided to use FS 75W-90. The gearbox was drained and -90 added. All is well. Took a bit of time to fix about three weeks due to shipment of parts etc. Porsche America supported and provided a respectable compensation for down time.
