1999 Boxster manual transmission fluid change

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.

This is right, 2000 and older use a special oil. It is not the same oil for the later models as Rick very correctly states. It will make a difference, I went to the dealer and they sold me the gear oil for the later models, and its did not work, the shifting was balky and when I put in the correct oil, it shifted perfectly.
