Today I went ahead and changed the TC fluid. I haven't had any symptoms so far but wanted to be safe. Its a 2016 base V6 with 47,876kms./29,683miles. The fluid was pretty dark. I used the Porsche "63" fluid.

 

I'll be interested in hearing how this dealer (newish) treats you. Sounds good so far.. and CPO is a wonderful thing.

 

My 2014 Cayenne GTS is getting a new transfer case under warranty. Since buying it CPO a few months ago, the downshifts have been rough. When I brought the vehicle there on the original service visit a few weeks ago, suggesting from my RL reading a possible transfer case issue, the dealer service rep told me that a bad transfer case features rough up shifts, not downshifts. They did software tweaks to address my complaint. Now that I’ve taken it back with the same persistent issue, they say I’m getting a new transfer case.

BTW my CGTS has 15k miles.

 

Chalk me up for a new transfer case... got the TC replacement (cover under CPO) scheduled yesterday.

My Mom has a 2013 GTS we bought almost 1 year ago. It has 53,050 miles on it right now; 45,900 when we bought it. We were on a long road trip this past week, and I quickly realized something was not right. Once everything is at operating temperature, 2nd 3rd & 4th gears all exhibit the jerky stuttering and sometimes harsh upshifts. Upon my description to an SA @ Porsche Nashville, they plan to replace the TC. He said they even keep them in stock...

 

Don, what is the correct torque on the drain and fill bolts? Is it 13 ft.lbs.? Thanks for all your help on this forum.

 

Looking at used cayennes....is it possible to tell if the transfer case has been changed by looking at it? Some of the vehicles don't have complete records.

 

From the factory manual:




Err on the side of less..

 

Dropped car off on Wednesday on way to Stewart airport for a quick 3 day trip to Ireland. Part was supposed to arrive Thursday but came in on Wednesday.

Made arraingements for SA to leave car outside for me to pick up Sunday on way home from Stewart (for those on in NJ, all NJ car dealers are closed Sundays).

Car was done by Thursday (got a call and email) and right were it was supposed to be for pick up last night...washed and ready. SA will mail other key to me.

Another great experience from SA Rob and everyone at Toms River (Ray Catena) Porsche.

Car runs great! This is my 3rd experience with this outfit and all 3 have been spot on.

Can't recommend them enough, they are new but have a well trained group of techs that they've rotated from their other PCar dealerships.

So to recap, brought car in on a Monday )at about 4:30 pm), diagnosed in 5 minutes. Part ordered and arrived, one day earlier then promised, on Wednesday, work completed by Thursday.

A+

 

Thanks for the feedback on them. I haven't visited yet - sounds like I should..

 

For those on the fence. high possibility that i'm able to change the transfer case fluid faster then filling up 25 gallon fuel load on the vehicle (empty to full). It's that simple.

 

Wondering if anyone else with a faulty TC experienced this symptom that I recently noticed: driving in 3rd gear under steady moderate acceleration, the engine revs drop about 300 RPM then climb steadily again. It feels exactly like the car is shifting to 4th gear, except it's not, it's still in 3rd. I noticed this more going uphill. It shifts through the other gears ok, although there's a little jerkiness from time to time.

2013 CTT with 58k miles, got CPO. Thanks in advance.

 

So a quick update from me. Car had to go in for an oil change and asked them to flush the transfer case fluid too. However, noise did seem to be getting worse though. Took it back to the specialist who had it for a few weeks to try and find out if it was anything else! Well it was worth a try at least. Anyway, we narrowed the search to the transfer case again and actually had the solenoid disconnected to test things out. Its amazing how noisy the transfer case is when it slowly builds over time. With the solenoid disconnected, the transfer case isnt in use and the car is effectively rear wheel drive. Anyway, it drove perfectly and quietly so we decided that we needed to replace the TC.

After a few weeks trying to find a suitable reconditioned unit, we went for a brand new unit. So unfortunately I am a statistic - a 2011 Cayenne S with just over 100,000 miles and a replaced transfer case. That said though, its quieter, smoother and I am so pleased its been done. Ok, so I dont like the cost involved, but the car is much better. I cant believe how bad things were getting, I guess its the gradual deterioration that gets missed.

Oh, and one final comment - 2 years warranty on the TC though, so thats something.

 

Can anyone who had transfer case replacement at dealer please post pictures of paperwork, curious if there is a new part number for the transfer case.

 

Was it 100k miles on original TC fluid ?

 

Kirill,

I posted my parts list over on this other thread, back when dealer replaced mine...
