Technically no. I inquired to this tech I talked to about the fluid a few weeks ago. He said they have cars coming in with 100k+ and the transmission fluid is stark black and thinner(it should be blue), they called Mazda on it and Mazda was adamant that the fluid doesn't break down and doesn't need changing(well, obviously it does since the fluid has changed colour and viscosity!). I know when mine reaches 60k, I'll be doing a drain and refill of ATF.
Seriously? It doesn't break down? Now...I would believe them if they said "the transmission is engineered as such that any break down of the fluid that will occur, will not adversely affect it." But...seriously...does NOT break down? Jeez.
I'm tempted not to. Just because my dealer doesn't recall ever doing that fluid change. Seems to me the trans should go 200 thousand miles at least on oem fluid. I know plenty of vehicles that have.
