I'm about to replace my valve body on my 2004 Cayenne Turbo, however this is quite confusing as it seems there are multiple different version of valve bodies with the same part number (955 325 039 00 ) From what I have found in researching, there are three visually different versions of this valve body, each pictured below. As you can see, there are two versions which have an additional 'port' or hole, one of these has a metal plate covering it, where as the other is left open. Finally, the third version has no port or opening at all. I ordered the original part number valve body for my 04 turbo, and I have received the variant in the first picture (3 port). Until I remove the transmission pan to do the replacement, I won't know whether or not this is the same or different as mine. Some things I have read suggest that the valve body simply had a different casting in newer years and these are interchangeable without an issue. What it says in the photo above seems to contradict this though, and suggests it is crucial that you use the same as what your car had originally. Another uncertainty regarding this is the TCU, and whether or not this needs to be changed or updated to suit different valve body versions. Searching for these questions on the internet is met with very little luck, and many contradictory answers. I would be extremely grateful if someone who is knowledgeable in this area can shed some light on this for me, as at this point I'm totally unsure about what is true and what isn't.

I have a 2004 Cayenne Turbo in need of a new transmission valve body (yep, that's been said many times before I know). However, it seems that since the last topics on this issue were posted back around 5-10 years ago it's become significantly more difficult and expensive to track down quality rebuilt valve bodies for these cars. Many of the businesses that people used to reccomend such as RevMax no longer supply these valve bodies, and looking online most of the businesses that claim to sell them look incredibly shady and untrustworthy. On eBay, most rebuilt valve bodies for sale are cheap knockoffs from China or from dodgy looking shops in the US that claim they are rebuilt but they've just come straight out of old cars (as per buyer feedback). There has to be something in between all of these questionable units and a genuine brand new one which is something like $2,500 (or nearly $4000 in Australian dollars which is my local currency). Has anyone gone through this process in recent times and managed to find a quality rebuilt unit without having to go to Porsche for a brand new one? Any advice would be thoroughly appreciated.

I have an 04 CS with 112K and a failing valve body. Classic hard downshift from 5-4 under load and occassionally from 4-3 while coasting to a stop. It's been scanned and no codes came up, just slamming into gear. I sent a certified ford mech friend of mine on a search for a source for a valve body and he sent me a link to http://www.revmaxconverters.com I am wondering if anyone out there has any positive or negative feedback about this. $659 sounds pretty cheap, and my favorite saying is "you get what you pay for". I don't want to waste $$$ on this and paying to have it installed if it is junk. Thanks for any recommendations that you can pass along. Here is the direct link to the part: http://www.revmaxconverters.com/index.php/valve-bodies/updated-oem-replacements/09d-tr-60sn-488.html?
