Hello all. I know this is a GM forum, but I do have a question about a Honda and other forum members have Hondas as well. My brother is needed to get the automatic transmission fluid changed on his 2003 Honda Accord V6. The dealer quoted him $100 for this service. IIRC all you do on the Hondas is pull the auto drain plug and fill it back up. Also reading his manual it states that use Honda ATF-Z1 fluid. I called the dealer, and it looks like ATF-Z! has been replaced ATF-DW1 fluid. My question is, so you really need to use the Honda fluid or can you use the Valvoline Maxlife fluid? Thanks.
