I am confused and can't seem to find the answer by searching, even though I know this subject has been addressed several times. But since I am going to have the transmission fluid changed this AM I will ask again. I was under the impression that the QDII took a different fluid than the ATF-4, but that is all that is listed in my owners manual. IS this correct? My XK is an 06 4.7 with QDII.
