I'd listen to him...he kinda knows this stuff pretty well..

New info: I contacted the folks at Sunset, asking about their transmission oil. He replied, "This is the Mobilube PTX 75w90 transmission fluid. Porsche only sells it in 20 liter containers so we break it down in to individual liters for our customers."

I was thinking the "Porsche stuff" was a Shell product. I'm not sure exactly what constitutes OEM transmission fluid in P-cars anymore. Is this Mobil product the one that is so much better than the other oils out there? The stuff that you, JFP, have had customers drain out other transmission oils to put in?
