I think I ordered 8L. I cant recall. I pretty much put in what I took out and the addition of the AMS tranmission cooler. I found my old receipt and apparently I ordered 9x1L jugs and paid 148$...I can see they upped the price because its in high demand now. I have half of one left over. Dont ask mere where the last liter went. lol.
Quoteing MTZL: Yeah 2009 has 3 drain plugs.
you should at least have 7L-7.5L.
