You used that part number on your diesel Cayenne??

 

Affirmative. When the parts guys went into PET that new fluid came up as the latest for my diesel. The diesel and hybrid have more simpleminded TCs that are fixed ratio. They just don't stock the new fluid at my dealer. One bottle does it.

 

According to the Parts Katalog, diesels should use 958 341 536 00, not 000 043 305 63.

 

I don't know what to say. The dealer parts guy looked up the TC fluid and came up with the new P/N for my diesel. Since they don't stock it they used the bottle of new fluid I purchased from Sonnen.

Update: I was at the dealer the other day and the parts guy concurs with your part number 958 341 536 00.

Update #2: I changed the TC fluid to the Diesel P/N this weekend. The old fluid at 7K miles still partially clear.

 

Add me to the list. my 3-4 shift was super rough. Brought it in and got it replaced within 2 days. 2014 base v6 with 25k miles.

 

One more to add. 2012 CTT with 78k miles. Being replaced under CPO after me mentioning odd transmission performance 2x before. Rough shifts between 2-3 and again 3-4.

 

 

I think so. So far everyone has been pretty solid on the "TCs on diesels are not impacted"

 

The important part will be if your original complaint is actually addressed with the transfer case change. There's always the opportunity to make the wrong diagnosis and draw conclusions from there...

 

First diesel I've heard of needing a TC replacement.

Of course a TC case can go bad on any vehicle, even those not know to have an inherent issue with them, so this doesn't necessarily mean diesel models routinely have this problem too like the gas models. You could just be an unlucky winner of the 'TC lottery'.

 

For what it's worth...
My Mom's '13 GTS has had the TC replaced (I posted this earlier in the thread)
My '14 Diesel with more miles than her '13 GTS is doing fine. If anything changes, I'll definitely post back.

 

True. I think I actually had overlap with my first symptoms being the TC (replaced),.. but then a month or so later my rear Diff made enough racket for me to notice it too (replaced).
... At the final stages of my denial on TC, I think I was also probably denying anything was wrong on my rear Diff too. I recall thinking.... "naaaa, that's normal"..... haha!!!!
2012 CTT w/ PDCC & PTV.

All good since both were replaced though.... 9 months on TC, 8 months on Diff, over ~ 8k miles.

Don- Speaking of lovely LA traffic, it seems that I occasionally in stop and go traffic I sometimes experience a hard downshift from 3-2 only. Been trying to force the 3-2 down shift with the manual mode, it has the same hard down shift or kick. Need to test further. The transmission has 37,000 miles, was replaced in 2015. The XC is has not been replaced,163K on the clock. I changed the XC fluid twice to the (Porsche fluid) about 3000 miles ago and about 4000 miles before that.(Ravenol)

None of the known XC conditions since the last fluid change.
quickster2-Cant wait for a XC rebuild fully documented.was there a core charge?

 

On the invoice the core charge was not called out. I believe they only give you around $400. e30rapidic is rebuilding his waiting on an update here.

 

Jay,

If you have an iCarScan - I'd suggest doing the transmission adaptation clear procedure. It seems the transmission can learn bad habits in places like LA traffic - resetting the adaptation lets it start learning better habits. Be interested in any noticeable change you may experience.
