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

oddly, i can't find a drain plug for the 6-speed on either the 986 PET or the 996 PET. the good news? it's the same as the 5-speed. your part number is 111.301.127.E. list price? $5.24.

as for gear oil? it doesn't have to be that complicated. just use a good one! don't overthink it. redline MT is great. my personal favorite is swepco 201.

insite,

thanks for the comments and data, i'll take care of the drain plugs with the gear oil change.

Redline 75W-90NS GL5 then ?




You have the Sport Classic II's ?

i'd actually go with the Swepco 201; i like it better than the redline. cheaper, too.

i do indeed have the SportClassic II's; they're 996 offset. love 'em.

the cheapest i can find the redline for is like 3 bucks cheaper than the OEM oil from the main dealer.

i guess for the cost difference its worth getting the OEM product, unless there is any reason not to.

Drain and fill plugs on order!

cheers.

BTW love the Sport Classic II's myself.

do you have an aversion to the swepco? i have used OEM, Redline & Swepco 201. i prefer the swepco by a significant margin; much smoother shift & better cold weather performance.
