Yes, it's very unusual for your typical 37,000 mile car to have black trans fluid, but when you throw in the age, it's not unheard of, and IMHO, not at all surprising.
That particular Mazda transmission turns fluid dark in Mazdas as well, with about the same mileage and less years.
Funnily enough, Ford recently allowed that tranny to be filled with Mercon V, years after Mazda put out a TSB warning Mazda owners that Mazda MV is not the same fluid as Mercon V.
I have used M1 ATF in mine from the start. At one time M1 ATF had the Mazda MV spec, but later dropped it. Mobil tech told me M1 would serve my trans well, and it has for nearly 200K.
