Was able to download, but I am thinking this is the wrong article for changing the transaxle oil, no? Talks about gaining access to the top of the motor through the rear luggage area. Unless I'm totally confused, I think the fill and drain plugs for the transmission should be accessible from under the car, no?

Holy hell, Porsche recommends changing the transmission fluid ever 15K miles!?!?
Is it just me or... is that kind of a lot???
I'm new to the manual transmission world (bought a manual S550 GT about 1.5 years ago), but I know my auto cars didn't need near that much care.

On my first post I mentioned I used Redline. Redline NS was recommended by Guard, I was running a Guard LSD at that time. Redline was also the original fill when the LSD was installed by Bodymotion.

EDIT:
Porsche's official guidelines specify to change it every 120K miles, which seems ludicrously long to me -- although they also say that you can go 6000 track miles before changing the oil, which I have no intention of doing either. As I said in my first post, people who track their cars pretty consistently seem to change their transaxle oil every 10K miles (total, not track), which seems surprisingly short to me, but if the fluid is only $40 and the procedure is fairly straightforward, I guess it's not too bad. On my E9x M3, the guidelines were every 45K miles and I changed mine at 30K.

But, I think you are right in that if it is cheap and simple, do as recommended on here, around every 10k total miles, or after around 6 track weekends...Mine just crossed 11k miles, so it is a nice reminder for me to get this done.
The interesting thing was that he told me to replace my spark plugs every 15k if I track the car as it operates at much higher rpm ranges than usual.
As another interesting reference, on my C7Z06 the manual stated to replace the diff oil after every 24hrs of track time. This equates to 48 30min sessions, or 12 DE days, or 6 DE weekends. Which is pretty much what is recommended by some on here.

Interesting. Porsche spark plugs at least aren't anywhere near as expensive as the E9x M3 spark plugs that double as knock sensors. On that car the official interval is 37K, although my car ended up telling the techs to change them around 25K (and those who supercharge their cars are supposed to change them every 8K). Porsche's official guidelines say every 40K, so if I shorten it at all I'll just drop it to 20K along with the other items in the "intermediate service" guidelines. I've also read that on the 981 the spark plugs are kind of a pain to get to.

Here is a diagram from the workshop manual showing the gearbox fill (1) and drain (2) plug locations (very close to rear axle line.) Tightening torque for each plug is 40NM (30 ft-lbs) and use new washer on each.

Added technique, remove the fill plug before the drain plug.
This protects against being stranded by a frozen fill plug and makes the drain more uniform.
Otherwise, sometimes it will splatter as air tries to enter as oil is flowing out.

FYI - I have used the pump pictured in your instructions on my 911 and it works great with one caveat. I think it's a good idea to break off the two prongs on the end of the filler tube as these tend to otherwise break on their own and it would be better not to have them swimming in the gearbox.
