Hello everyone,
i have to change 991 pdk transmission oil & clutch oil, I am having a hard time in locating the drain & fill plugs for them...
I believe while standing in front of car, left side is for transmission oil, surely the transmission oil drain plug is at the bottom of black colour sump & fill plug is at left side of housing & no idea for clutch drain plug..I have heard clutch fluid is supposed to be filled separately then transmission fluid....? Both of them should not be same oil & same plugs.... I am confused.
Thankyou for having a look at this thread ...

 

I think you’re a little early on this
these need to be changed at 120 K mileage or 12 years whatever comes first
Four-wheel-drive controller gets changed at 60,000 or six years which ever comes first

 

This should help.

There are more posts if you run a search.

mikerosi is right, but if your car is modified and you track it hard, I would change it much more often. My car has 12k miles and I have changed it twice already.

 

Such as coincidence. I am also looking into doing this soon. I've found that between the clutch, PDK, AWD controller, and final drive there are 4 fill plugs and 5 drain holes. There are two types of fluids need :

• 4Liters of Mobilube PTX 75W90 (I've only been able to find it in single liters from Suncoast)
• 6Liters of Pentosin FFL-3.

Below and attached are some threads, videos, and documents that will help.

I was just quoting the maintenance for normal use
Of course if you track your vehicle then yes you would want to do it more often

 

Thankyou everyone for such amazing responses...it is more than I could ask for....yes car is used for track events.

 

Am I right about the location?...
the plug for clutch fluid fill plug is behind the pipe & ATF is on top- rear side right guys ?

 

hey. Just saw your post. You have the clutch fluid fill correct (behind the pipe). You do not have the right trans fill. It’s on the other side.

 

mikerosi and Jean, you guys are so far off. Porsche workshop manual states, "Even if car has been driven 0 miles, every 5 years clutch fluid must be changed.

 

 

I made this tutorial a while, if anyone needs it. Use at your own discretion

 

No it states that if a car sits for 5 years or more, the fluid must be changed. Says nothing about changing fluid every 5 years for a car that's driven.
