955618022AX is the remanufactured version of 95561802203. That will also work for you, but you'll need to send your current control unit back as a core. I don't think 95561802212 will work for you, but it might be worth trying if you have it laying around.

Thank you Tim for helping.

My TCM has SW 0363, according to this TSB I need sw600. So if I buy new 95561802203 TCM, wil this one have that updated sw??

Unfortunately I don't have 95561802212 TCM, I just have option to buy it used for good price.

I try to call few Porsche mechanics, but I can't get any answer... I would be so happy to pay for right information, but looks like that is impossible in our country...

The new TCM should come with the updated software, but it will still need to be programmed to your vehicle by a dealer.

XR4Tim, I was wondering how you found out the part #'s and if the would work? I have a '06 Turbo S and had it into the dealer for some other work (PCM Reprogramming) and I specifically asked them to check the transmission software and they said I had the latest and said they didn't need to re-program? Leading me to believe there was some kind of Piwis programming that the dealer can do?

You can find part numbers in PET.

I also believe, that 06 models already have updated software.

If I order 955618022AX from ECS tuning, I have to send my old one back first? Or is there any chance to send it back after I get new one?

XR4Tim

You can send it back after you get the new one, but you will be charged a core charge up front, which will be refunded when you send your old one back.

XR4Tim

Yes, there is some level of reprogramming that can be done (at least on the newer control units). I believe it was just the early control units that needed to be replaced in order to get the correct software.

That's great, and how much is core charge?

I don't know if I can discuss these here, if not please let me know and I'll send you pm or leave me your mail.

Thank you

Ok here is update.

I replace old TCM with TCM 95561802212 which have sw0602. There was no need to update DME.

Now, rough up-shift 1-2 when the car is cold, is completely gone. It shifts like butter in all gears.

Also throttle hesitations in corners is almost completely gone. It's no 100% perfect but I can live with that.

Very happy

Looks like you have the 'updated' valve body. That is a 'check valve cavity and retaining bracket'. Nothing else required.
To confirm, your old VB should have 'A-3' stamped on it and the new should have 'C-1'. It should be on the top left corner of the VB using the your photo for orientation.

I suspect Porsche does require the new TCU for this new VB (I got the same story from my dealer in Northern California). I am no expert on this. To avoid that extra cost, I removed mine original VB and had it rebuilt so it would work with my original TCU.

If we may know.. How long did it take to get the valve body rebuilt.. by whom.. and at what price?
