Which transmission fluid to use in manual 996?

I've read numerous stories of 996 owners that used other oil in the transmission and experienced problems. Going back to the factory lubricant solved the problems.
When mine is changed, I'll be using the factory oil.

I ordered the Mobil Delvac 75/90 from Suncoast, still waiting for the shipment to arrive. $40 or so per gallon plus shipping. I'll be interested to see if shifting improves or declines. Only have 15 to 20,000 on the last fill and drain after the dealer did some transmission work. Starting to feel a bit difficult in the 1st to 2nd gear change.
Can anyone confirm on a 2004 whether the drain plug is a hex or triple square bit?
Thanks

I've had the car for 50 kmi. I don't know whether the transmission fluid had been changed before that. I was really surprised that it looked so clean when I changed it. The color matched that of the fresh Porsche fluid that I pumped in.

I used Delvac 72w90. Shifting has definitely improved. The oil that came out was dark in color. Took a little over 3 qts.

You may want to try Motul 300 next time then since at least you have a reason to experiment outside of P fluid. There are a few happy Motul 300 users here on RL.

Thought I'd post a brief update. I have no allegiance to this dealer, but it took me a while and some phone calls to figure this so thought I'd post it to save someone some time. Other dealers may also carry the same
Sunset parts has the Shell oil that is recommended by Porsche in 2 formats.
999 917 546 00 Shell Transaxle (75W-90) in sealed original 1 liter bottles from Porsche is about $30-35/liter.
They also have the 20 liter barrel of the same oil from which they can take liters and send them to you unsealed in their bottles. This Part Number : 000-043-204-19-SP and is about $25/liter.
Hope this helps someone save a little time.

I've had the Porsche manual transmission oil in my car for over a year and I have short-shift kit. Shifting into first and second gears is a bit hard on cold days before the car is warmed up. After that, it's fine.

Just buy the stuff from the dealer and get on with it. Honestly with such a large service interval you'll probably never do it again - how much are you actually going to save, and at what potential cost? It takes 2.8l if I remember correctly. $120 well spent for peace of mind and having the right stuff in a critical and very expensive mechanical system.
It always surprises me how people love to talk about the driving experience of Porsche and then undermine that experience with inferior aftermarket parts. These cars are a collection of everything that goes into them and when you begin swapping pieces out you're changing the entire system. I'm not trying to pick on you specifically, this is more of just an overall observation that I can't quite understand and goes beyond just transmission fluid. If, for example, these transmissions had a habit of going bad and the oil was suspect then it would be prudent to investigate better alternatives - but why even waste the time otherwise? Especially when discussing a potential savings of maybe $60 of the entire time you're going to own the car?
For what it's worth I used Porsche brand fluid in my transaxle and front differential. It took 5 quarts all together. It was expensive. It's a Porsche.
