I think B-man is right, I have 2014 Cayenne Diesel. The transmission type is Aisin AN2, TR-81SD. The ATF should meet the Aisin AW1 specification. I found only Fusch Titan ATF 4400 meet this specification. I was not able to find separate filling hole on the sides of the transmission. Regarding the filling process there is one thing I am worried about: if we use the drain/fill plug for fill the pressure in the transmission should be building up because there is no bleeding space hole. This can prevent to push enough ATF into the pan. If you check the fill level by removing the filling tube than the pressure is gone of course, but how the factory adapter We1389 is working in this case? If they open the valve checking the level then the pressure will push out the oil remained in the copper needle. If it is not overfilled than the oil drip should be stopped shortly after the valve opening. If it works this way than it is messy.
