Transfer case
#1291
i have always noticed a jerk when starting from a stop but only once and only when car is first used for the day - when i purchased it (private sale) the PO gave me an invoice from a local porsche dealer for a replacement of the transfer case in january 2020 - i looked under the car and the date of manufacture is 8/19 - this date is on the cover of the electrical box on TC - so i assume it was done and has the new improved TC - i took it back to dealer who did replacement and they couldn't find a problem - it's not really a big issue and i'm not sure it's even the TC - should i take to a different dealer to check - would this still be under extended warranty (car was put into service 2012)
Also, the software version 1150 on the control unit indicates you have the newer reinforced transfer box that has not been shown to have the same issues as the prior versions.

r553 - yes i did the transfer case fluid change 3 months ago ...no change - garrett376 - hmmm..that makes me think - i changed the transmission fluid and filter about 6 months ago - i tried to put back in exactly what i took out and it was dripping out the fill when i sealed it up - old school used to be you NEVER overfilled an auto transmission or it would develop leaks, so i do tend to go on the less is better side - i'll try adding a half liter and report back here

I have a 958.2 Turbo with 36,000 miles and has had two TC replaced. What is annoying to me is the response delay when you step on the gas hard and the car finally decides to move. I have tried other ZF’s 8 speeds on other SUV’s and for some reason the one on mine feels ancient technology compared to newer cars. Might be just programming, or is the TC design as well?

2017 CS w/ 48k miles, bad transfer case
Hey guys, I saw you were trying to keep a list of diagnosed transfer case issues. I just had a 2017 CS w/ 48k miles diagnosed with bad transfer case. I have scheduled to take in for the repair in a couple of weeks and I feel like it's getting worse by the day.

Not sure what the correct vocabulary is to describe it. I would describe it as a pulsating acceleration in second and third gear. It just doesn't accelerate smoothly and I could feel a repetitive slipping that if didn't know was the transfer case would think is in the transmission.
Another thing I could see and hear is that second and third gear almost engage in two steps - on upshifts to second and third, the engine rpms first drop a to about half way to where they should be when fully engaged, hover there for a second or two, and then fully drop down to where the gear is fully engaged.
And importantly, all of these symptoms only start to appear after the transfer case has a chance to get close to full operating temperature. So if it's cold outside, you may need to drive around for 15 - 20 minutes before you start to feel it.

They might goodwill that repair as it is a known issue especially if it has been done once already on your Cayenne.
