Also does anyone have a DIY link for this?

There is a basic reason why you cannot get agreement on what type of gear oil Porsche uses; because they use a totally unique product that is made just for them. As the result, most major gear oil companies (the truthful ones anyway) simply say they do not have a suitable replacement, while the hucksters will tell you theirs is a perfect substitute……

Knowing how much these gearboxes cost, and that the OEM fill is a readily available and inexpensive full synthetic product, going to Sunset and buying the OEM fill is your best bet.
