    Which Transmission/Differential Oil for 996 TT ?

    in 996 TT, 996 TT S, 996 GT2

    Posted · Edited by Dave at Red Line

    I was going to have my Manual transmission /Front differential fluid changed . The car only has 15k miles but it is a 2002 and I am always ahead on fluid cahnges. My mechanic is prepared to do it for me as long as I provide the fluids. Short of buying directly from Porsche dealership ...can anybody advise as to what is the original factory fill fluid, is it a special Porsche formulation or can I buy it without the Porsche branding?

    Would it be better to use an alternative product? The car is predominantly driven on the street in very high ambient temperatures .I see alot of guys mentioning Redline products.

    Thanks for your suggestions.

    In the 996 as well as most Porsche manual transaxles we recommend the 75W90NS, a suitable replacement for the PTX fluid. The NS contains No Slippery additives so isn't too slippery for the synchros, a problem with most gear oils. In the front differential I would recommend the 75W90, it contains a friction modifier, beneficial to the separate differential operation.

    Regards, Dave
