"Normal" - no. Uncommon - also no. It happens. That's early failure mode stuff - where a part inside the case was machined wrong when the case was built. It's under warranty? Let the dealer put a new TC in. BTW - the usual failure mode is slipping followed by grabbing under acceleration when the transmission shifts, particularly the 2-3 and 3-4 shifts.

Just got my new to me 958.2 CTT CPO with 43 Km , Jan./2016 Build , shall I worry about the TC ?, asked the dealer to change the oil was told to enjoy it and not to worry.
the problem I live far away from the dealer and thinking about just pay for the oil change and get it over with.
I have no issues thus far with my short time driving it. except a small jerking down gear before stopping while in Sport+ mode
and one thing for sure unlike my old 06 CS no transmission bucking .

Since you're far from the dealer, start asking around to find the good foreign car independent in your area. Get them to change the fluid. Labor cost shouldn't be more than 30 minutes (including the time to put it on/off the lift.) Order up two new plugs for it from an on-line dealer, and a bottle of our suggested Ravenol oil. If the case ever does fail - don't mention the oil change to the dealer.. they'd likely use it to deny warranty coverage. FWIW - I was quoted several hundred dollars to have a dealer change the oil (free coffee and a carwash don't come cheap I guess..) and people have gotten quotes of up to $700 for what's basically 15 minutes worth of work.

Yeah - dealers do that. Ask for the service manager - not the "Service Adviser" (who is there to sell service, but often doesn't do that very effectively.) The dealer doesn't care since the car is CPO and it would get a new TC if there were problems. More money in it for them if they change out the TC.

will buy two new plugs as suggested, lucky for me I know a gentlemen close by who did work on my old cayenne and he is very good.
much appreciate the help,

I also asked my dealer about changing the TC fluid and they said they wouldn’t bother. I chose to heed Don’s earlier comments about what happens if it fails after warranty..the dealer won’t pick up the tab. So I went ahead and changed it but used the Porsche fluid and took photos for back-up.

That is a very good advice thank you for the encouragement, I thought about what you have proposed but got cold feet fearing of being denied coverage if something happened.

I would encourage anyone to make them change it before you buy it. Mine was a CPO but before I picked it up I asked them to please change and they did. I even sent them the link to this thread. I didn't get any push back whatsoever.

Does this thing look like transfer case rebuild kit: https://www.ebay.com/itm/ATC350-450-...-/263086908030
Parts diagram: https://awd.tech/pages/pl72atc-diagram

Not that I am planning to buy it, but if they sell it - there must be a demand for it - I guess someone figured out how to rebuild the TC

Took my CPO 2013 CTT (64k miles) to Porsche dealer last week with the scraping-grinding-while-turning-sound. They implemented campaign WD31 - Re-Program Rear Diff Lock Control Unit but the noise came back within a day so i'm taking back in next week.

I have ordered (picking up today) Porsche magical differential juice fluid. It's 1.2 qrts for the rear and .5 qrts for the front. I'm changing this weekend and i'll report back. Thus far i have done Transfer Case thinking it was that. I had no change in TC but i never had an issue with TC grind / rpms jumping.

Do you have PTV Plus ? I do and i have what you're saying above. I had the differential flashed with the new update. I would say the sound is more like traction control kicking in.

Also had my TC replaced under Good Will last Spring,.. which certainly did help the TC problems I was experiencing. But the grinding in the rear under slow turn conditions seems to be something completely different than TC. Although it has indeed been mistakenly discussed in "this" thread.

Yeah, has PTV. And i agree that it sounds like traction control ...like clutches slipping/chattering...they think its the diff. and not the TC.

It's a very different symptom from a failing TC.
