ATF, transfer case, front and rear diff changes on 09 CTTS?

[royxaxa]

thinking about getting an 09 CTTS with 110k kms. if I do I would like to change all fluids possible

any changes to ATF, transfer case, front and rear diff?

I had changed these fluids on my old 04CTT with great results.

thanks

Same procedure on the '09 as in your '04CTT. I highly recommend it.

thanks hahnmgh63, I would assume the same fluid as well?

when I changed the transfer case fluid in my 09 CTTS it wasn't ATF that came out it was definitely gear oil of some sort, it was a slightly dirty (55000 miles) but still gold just a bit browner, after checking the Porsche parts catalogue for the part number, 000.043.301.36, I crossed ref'd that to VAG G052515A2. That's what I put in my TC.

I just searched on autoatlanta.com and it shows the same p/n as you provided and the description is transmission oil. 

the website also suggests a Fuchs Titan ATF 5005 as replacement. and that is an ATF for automatic transmissions.

I also checked the p/n for 04 CTT which I had changed fluid twice before, they are the same parts on the catalog. I used 71141 ATF before.

could someone clarify this?

thanks

For the transfer case the last Porsche recommendation was the LT71141 ATF which many synthetics can meet that Esso spec as well as the JWS3309 which is the Tranny spec. I used Redline D4 in both as it exceeds both specs. The newer VAG G052515A2 replaces the older G052162A1 for older and newer Touareg's. I'm sticking with my Redline but if you order the VAG part from an Audi or VW dealer it does come conveniently in a .85 liter container.

The transmission recommended fluid by Aisin and Porsche is a non synthetic fluid.

Subsequent use of a synthetic fluid has been known to cause leaks from the seals, especially if the transmission has been using a non synthetic fluid (such as the Porsche approved fluid).

Porsche will void any warranty on the transmission if a non approved fluid is used.

bigbuzuki I would say at least here in N. America, if the Porsche spec say's it must meet JWS3309 and you use a fluid that meets that spec whether from Porsche or someone else or whether Synthetic or not then there isn't a thing Porsche can do to the consumer. It's a Consumer rights thing whereas a manufacturer can't force someone to purchase only their Mx products when others than meet or exceed that spec are available. Not sure if that would apply in the land of Oz but it does here. Porsche would have to prove that beyond a doubt that the fluid didn't meet the spec and/or caused the damage so the fluids manufacturer would most likely be liable if they had listed that their fluid meets or exceeds the Spec listed.

As for the Synthetics in non-synthetic originally equipped vehicles, I have heard of those stories in the past but I believe with the more modern Viton and Silicone rubber seals and O-rings it isn't much of a problem nowadays. But I'm not saying it couldn't happen. My pig had about 38K when I swapped all of the fluids to Redline and so far, 30K later all is good and dry. Shifting is improved with the Redline over OEM but whatever the choice, I would definitely say to swap out the fluid much earlier than Porsche's 160K interval.

Here in Australia, Porsche will void the warranty if unapproved fluids or parts are used.

Outside warranty you would have to let the lawyers fight it out.

An expensive exercise for using unapproved fluid / parts, why would you take the risk?

Agree with early fluid changes to increase longevity of the transmission.

I've no idea what the situation with warranty claim rejection is like in Canada (the OP's from) but here in the UK they won't even fix things that I think are totally legitimate like front subframe bushes "wear item", seized brake caliper "wear item" and control arm bushes "wear items". I wouldn't want to advise anyone to inadvertently mess up even the possibility of a warranty replacement of a diff, transfer case or auto box given how much they cost.

 

Porsche dealers charge quite a lot for Porsche branded fluids. I found it useful to find out that Mobil ATF3309 is apparently identical to Porsche ATF (i think PN is) 000.043.205.28, that VAG G052515A2 is apparently identical to Porsche's TC gear oil 000.043.301.36 and that VAG G025145S2 is apparently identical to Porsche's 75W90 Diff oil 000.403.205.30.

funny I actually found 2 different Mobil 1 3309 at local auto parts stores:

1, the old Mobil super 3309 which specifies that the oil could be used for cayenne and whole bunch of cars

http://www.mobil.ca/Canada-English-LCW/automatic-transmission-fluid_mobil-super-atf-3309.aspx#

2, the newer Mobil 3309 which only says it meets the toyota T-IV

http://www.mobil.com/USA-English/Lubes/PDS/GLXXENPVLMOMobil_ATF_3309.aspx

 

I personally used the "Super 3309" before. seems alright. 

Typical Properties of these two has slight differences
