Changing Transmission Oil

[Bruce Wayne]

I'm also about to do a gearbox oil change and am reseraching appropriate oils..

Having reat through the data provided by posters it would seem for the 6sp that the OEM oil is best, however a call to my local Porsche dealership has given a price per litre of 20.00 for the US based that's 32 bucks a litre with the capacity at 2.88 litres that's 100 bucks in transmission oil. are you f... f... kidding me ?

Is the OEM oil THAT good ?

The other thing is that while removing the filler and drain plugs, i fugure it's worthwhile replacing those too.

The filler plug is the grand sum of 5 pounds. hey no biggie

HOWEVER.. in terms of the drain plug, the dealership tell me that the filler and drain plugs are probably the same (they also asked the workshop) as there is no part number listed in their tech manuals for the drain plug..


A reputable Porsche Parts supplier (my usual) is telling me that its a not available item..

again.. are you f... f... kidding me ? so a new drain plug warrants a new gear box ?

Guys what's the deal here !!

any input would be gratefully appreciated...



Car is not going anywhere right now as the company that refurbed the wheels over torqued 4 bolts on a rear rim and cracked it in 4 places
