2014 Cayenne ATF full service
 

I'm planning to do full ATF service DIY for my 2014 Cayenne Tiptronic-8 speed, 80 K miles. I pick up a few great articles from https://rennlist.com/forums/cayenne-958-2011-2018/1149998-transmission-fluid-change-procedure.html. Do I need PIWIS 2/3 to reset my transmission learning/Calibration?
Porsche wants $1k for the full service - Filter, gasket, and fluid. I have a lot of free time and WFH so I don't mind doing it.

Thank you for your feedback and watch out for tips for my upcoming task.

Pretty sure you need either PIWIS or another tool that can show you internal fluid temps before you cycle through gears.

Yes, I do need PIWIS to monitor temp of the fluid. I don't have it, my durametric is not good enough. I am thinking to buy PIWIS from VXDAS.
Many thanks for feedback.

Stunning !!! Porsche Fletcher Jones Dealer told me that $2,800 for all fluid service including Differential front/rear, Transfer case and Transmission ATF with Filter and Pan. for ATF Transmission alone is more than $1500 ... what the heck. I did differential front/rear and TC easily less than $200 with Porsche Fluid. The ATF tiptronic transmission is $400 with fluid, gasket, and filter.
Here is the question what diagnostic equipment I need to monitor the temperature beside PIWIS. My durametric is useless for ATF temp monitoring.
Thank you for feedback.

It takes certain hours of labor and I'm sure they can tack on more if they want/need and their labor is expensive (let's call it that). On top of it all, the dollar is worth like $0.75 compared to how it was before this covid scam. Inflation is crazy.

I used my ICARSOFT POR II. Worked great.

Good to know. Thank you for the feedback. I just bought Foxwell NT530 for Porsche $159, it works great for transmission temp monitoring for both Cayenne and Panamera. PDK.
Many Thanks. Ready for complete trans service.
