I have a 2012 Mazda 3 2.0 SkyActiv with an automatic transmission. I want to replace my transmission fluid, but I am unsure of which type Mazda fluid to get. The 6-speed auto takes one grade of Mazda fluid, the 5-speed auto takes another grade, but I am unsure which one I have. If anyone is familiar, mine does not have a normal auto transmission dipstick that can be found near the top of the engine. Is that a clue to which transmission? My owner's manual does not tell me. I tried a VIN lookup, but that didn't tell me.
