Pretty straight forward diy. Drain/filler plugs are #3 and #5 in the diagram. 44ftlb for the plugs. Add oil 50ml at a time every 15s.

Transmission diagram sourced from “Porsche Workshop Manual”.

As best as I can remember it was about ~6.5L

Cheers!
I'm planning to change out all running gear fluids at 14,000 Mi as someone decided to drive through flood waters which came up just above the bottom of doors. :(

picked everything up from Sonnen- great website and the service guy was super helpful.

Sorry, if you see the table below it’s 4.1L for the MTF not 6.5L

All of this info is available on PIWIS TSI (Technical Service Information) also someone posted the full workshop manual. I would recommend getting a subscription to the PIWIS TSI site that way you can get the most up to date info. The info I provided is for informational purposes only, I always get a subscription to that service for an hour I think it’s like $15 or something. That way your guaranteed to have up to date info.

Just did mine, seems I could only get 3 liters out, and then 3-1/3 liters back in before spill out? Had it level on a lift, let it drain for a while until nothing else came out.

So this change is not as straight forward with the Base Macan because the transmission brace covers the drain plug (#5), see pic.

I had to shorten a 10mm Allen key to fit in that space but once that was done the rest was easy.

3.2L came out and 3.55L went back in.

The transmission definitely feels better after the change. FYI, the vehicle has 36k mi on it.

BTW, thank you again ttmacan 👍

What’s the service interval for the front and rear difff for a street driven “S”, if I might ask? New CPO owner with a lot going on in life (otherwise I’d search). Thank in advance.

I think it’s 80k miles/8 years per Porsche major service schedule.

The service interval is 160,000 miles or 16 years
I would be weary following these type of intervals for performance vehicles. I did it at 50k and trans was shifting way smoother but to each their own.

You experienced smoother shifting from changing out the front and rear diff fluids? Why do you think that would affect the transmission performance? Not being the "know it all" here, always willing to learn from others.

Sorry for the confusion, I replaced all the fluids at once, trans, clutch, front rear diff and transfer case. After this everything was smoother.

The front diff fluid is shared with the actual gears in the PDK (this is separate from the clutch fluid in the PDK, which is the transmission fluid that is normally changed at 40k miles).

Yeah front diff fluid (mtf) would make it drive smoother. Rear diff would not affect shifting.
