I have a 2005 MDX and everytime I change engine oil I drain 3 qts of tranny fluid and add 3 new qts. Somehow I eneded up with an extra qt setting around----so time for an oil change. I ask my son to pickup 2 qts for me. What I've always got was ATF Z1---now he brings home ATF DW1 ???Did they change it or what---will they mix together OK???
