Clutch hydraulic oil to be replaced every 48K miles, gearbox oil every 96K miles. No special requirements in the race circuit warranty supplement for PDK-S....
2.95 liters of Mobilube PTX Formula A (SAE 75W-90) GL4.5 are used in the transmission
for lubricating the gear wheel set. 5.2 liters of Pentosin Gear Oil FFL3 are
used as hydraulic oil.
Above is for PDK box; expect similar for PDK-S

I was referring strictly to the transmission oil filter found in slush boxes,with no implication or suggestion the PDK-S is one...

Does anyone know what are the specific differences between a vanilla PDK vs 991 Gt3 PDK-S transmission? What specifics are different internally. Something been mentioned bout Lw internals- what exactly was changed? Mike

What is the gearing for the PDK-s. Is it similar to r/p change on the 3.8 rs or shorter? What internals in PDK-S was beefed up? I know they worked on the software mapping. Now are there trans cooler on the PDK-S? What's the weight difference between the PDK vs PDK-S vs mezger tranny? Mike

So guys who have tracked the 991 gt3 in automode- has pdk gone into 6 gear? Like the prev gen gt3's never used 6th gear- kinda wished they just used 5 gears vs a 6 gear box. Mike
