Hey does anyone here use the good Ole valvoline dex merc blue bottle for your trans? A couple years ago it was 16 bucks a jug and was called "valvoline dex merc iii" but now it is just called "dex/merc". Can someone confirm for me it's the same product? I've been doing drain and fills on my 01 tundra v8 (calls for dex 3 fluid) with it the past 4 years and want to make sure it's the same exact product. Also, what's the difference between the blue dex merc and the red valvoline max life atf fluid? Thanks
