I was looking for fluids for vehicles that take a WS type ATF and stumbled on Titan ATF 6400. It seems to be more specific to WS than the Titan 4400 that I see in a lot of 09G related posts on VW forums. Good luck finding it though, I could not find anyon yet who sells it. Now that Fuchs has bought Pentosin I wonder if that fluid is the same or similar to ATF1 LV now. Here is a link to the data on TItan ATF 6400: Fuchs Titan ATF 6400 Now when I look at the specs for the 4400 it appears to be more like Type T-IV. The data for the 4400 has VW part number G 055 025 A2 listed but the 6400 has G 055 540 A2. Neither of the to fluids lists both of these. Here is the data for 4400: Fuchs Titan ATF 4400 I found it when I searched Fuchs website using the VW part numbers.
