Help - '02 S Manual Transmission Oil Change

[SeanZ4]

barkinfool, How many miles on your 02S? Mine is a '00S with only 41k and the original trans fluid and I've been thinking about changing it. Did you use the Porsche brand stuff?

yeah, y'all must be right on the 911 transmission. i just saw it labelled 5-speed and realised quite quickly that it doesn't look anything like my 6-speed. upon further examination it deosn't look anything like a boxster 5-speed either. there's a few red herrings in 101projects; all those things that look so easy with the test engine out of the car are a different ball of snakes in real life. still an excellent resource, however.

i used redline in mine and am happy. i think it is jfp that is adamant that you use oem. always a good debate when it comes to lubricants.

I used the Swepco 201 as recommended in the 101 book, but for the first time ever my transmission is notchy until it warms up. Next time it will be OEM.

The later 6-speeds are also again a bit different. For one the slave cylinder cannot just be replaced with the transmission attached.

Swepco 201 is good for cars that get tracked but will be notchy. I was given a combination that so far shifts BEAUTIFULLY! Better than the stock fluid at 100K.

Sorry for the delay in getting back to you, I took a weekend trip & just got back.

Sean, changed it at 28,500 due to it being 11 years old vs symptoms or mileage. Used Porsche trans oil which was > $40 a liter so it is spendy, for 3L ~$130, but amortized over that much time not too big of a deal. Shifts well, not sure there is any difference from before the change, but I have more piece of mind.

Good call on the oil. Other are definitely problematic if you are in cold weather areas.

Great post and just in time too. I'm doing this project while Udo is laid up for the winter as well as installing a GBox 2nd gear detent, oil change and a brake fluid flush. Service records I have don't show Brake fluid replacement, so I figure it's high time.

I'm only at 83,000 km, but trans oil is 12 years old and I need to undress the bottom of the car to swap the detent, so trans fluid's getting done "while I'm in there".

Nothing like bonding and busting knuckles while the ride's in storage.

BTW, I got the Porsche trans fluid for $28.90/liter and Super Blue for under $18/liter from Suncoast Porsche in FL. Bought from them before, great to deal with.
