I drive the crap out of my 04 Cayenne S with some occasional towing and I guess an tranny fluid change won't hurt...

Porschelibrarian posted an few example pages of the Cayenne workshop manual that happen to contain the section on inspecting, topping off and replacing ATF.

Here's the document you can download:

This seems like a fairly complicated process requiring special filler tools.

Has anyone tried this?

It takes a few special tools and a lift, but should not be too difficult.

Im gonna do a ATF and filter change soon on a guys 04 cayenne s

Big 17mm allen socket to drain the pan.

Yank the pan, change the filter and gasket.

pelicanparts has the filter for ~$40 and the gasket for ~$60

The other plug on the pan has a smaller plug in the middle which has a tube going up where the full level will be.

To refill you would need a mityvac 7201 or similar to pump the ATF in.

In the manual they show to remove the cooler line and pump fluid through the lines.

But I will probably just disconnect it at the connection by the radiator and blow air through it to get the ATF out.

I was kinda pissed at the dealer when I ordered his differential and transfer case fluid so I could drain and refill all 3.

The t-case fluid is just regular old GM auto trac 2 in a german bottle......list was $57 for .85 liter!

What a joke, I had 3 quarts on the shelf.

The diff fluid was nearly the same outrageous price, should have just used some bulk 75-90 synthetic.

Needless to say, I will never order fluids from porsche again.

It seems like after you total up the parts it's not worth the time and labor to do it yourself. Anyone pay a dealer or Porsche shop to do tranny, transaxle etc? Costs? My 2004 CS is probably due but I was told by a dealer the transaxle fluid is good for 180K.

Dealer will charge you over $700

List price on the filter when I called them was ~$250 and the gasket was ~$80

ATF was ~$47 a liter....which can be bought cheaper elsewhere.

I will be using Mobil 3309 fluid, $6 a quart online, but I will look for it locally.

So $40 filter, $6 o-ring, $60 gasket, $70 ATF, $75 fluid pumper, add $15 shipping for the trans parts grand total of around $265

Also have to get the tools to remove the plugs and jackstands to lift the car up.

But it is still quite a savings.

What are the correct fluids for the Transmission, Transfer Box and Rear Final Drive? I am wanting to do all three myself and would appreciate any tips or your experience with this.

--I found the TSBs for Approved Oils 3702 and 3965

Anyone know a good indie shp in Denver / Boulder Colorado area that does the change for a reasonable price?

Just bought an 06 CTT S with 56k miles on it. Is probably a good idea to have all the fluids changed and things looked at.

What is the service interval for the trans / transfer case / and diffs ?

can i change atf in a lazy way: without opening the cooler line, simply change out the atf a few times to get rid of most of the old fluid?

[mudman2]

service interval for transmission is 200K

well, engine oil change interval is 20k, but i don't run the oil more than 5k in my ctt

In order to have the correct amount of oil in the transmission you need to fill it until fluid emerges from the fill hole when the fluid is 40C. So really you need a durametric or equivalent to do it like Porsche wants. You can change probably over 80% of the fluid without opening the cooler lines. The fill process gets more complicated if you open the cooler lines as well.

Thank you for your input, my friend. Too bad that Durametric doesn't support monitoring the transmission fluid temperature right now. Rumors are V6.0 non-beta software will support it.
