1999 Boxster manual transmission fluid change

[rick3000]

You definitely want to use the OEM Porsche transmission fluid, it is specific to the transmission, and people seem to have issues using non-OEM fluid. The PN is: 000 043 304 71. I do not think it is available in individual liters anymore, you have to buy a drum of it. However, Sunset Porsche sells it by the liter (they fill up empty/clean oil cans). You will need 3 liters, which runs about $80. If you try to buy it at the dealer, don't let them sell you anything other than that part number, it is not the same.
