valve body change

[colinmartin]

hi guys its looks like my valve body finally crapped out on my 2003 tt I have ordered a recon valve body, but what I would like to know is roughly how transmission oil should I buy in liters please and is the atf 3309 the only choice or am I wrong thanks..

JWS3309 is a transmission fluid specification and yes whatever brand of fluid you go with it should meet or exceed this spec. Some have went with the Mobil 3309 and some with the Toyota stuff which is supposedly the same as what Porsche sells at a high price. I used Redline D4 ATF which exceeds 3309 specifications and seems to shift better, and it is a full synthetic. There are other top quality fluids which meet or exceed the JWS3309 specification and would probably work fine.

The new quantity is around 9liters and they say the refill is about 8.5liters so get at least 9qts and a filter with a new oil pan gasket of course. Sometime in late 2004 I believe they increased the size of the oil pan slightly and the later Pigs take about an extra 1/2 qt capacity. Maybe someone will chime in with the exact amount. So if you haven't had your transmission or its oil pan changed the posted quantities above should work. If you are a contributing member there is a TSB which lists the quantities and another which lists the transmission # when the quantity changed as well as the new capacity. You will need Durametric or Vagcom if your a VW/Audi owner to plug into the OBDII port to monitor the refill as there is a procedure.

After all is back together you fill the pan to full, then start the motor and immediately start filling some more as the fluid in the pan is pulled up into the transmission. You stop filling when the fluid is dripping out and the temp is 40'C. If you get it filled before the temp gets there then just leave the plug out an let it drip while the fluid expands and the temp increase to 40'C. If you don't get it filled by the time the fluid gets to 40'C then you need to plug it and shut it off and let it cool for an hour or more, turn key on an make sure it is below 40'C, if so restart and start filling again immediately, better to let it drop below at least 30'C so you have some time to get it full. You will see how the funky refill periscope plug works, and just need to make a refill hose/tool to work. I actually have the Porsche/VW/Audi tool. They just have different adapters at the end but use the same tool. If you have a manual please refer to it or send me a PM if you have any questions.
