Mazda Maintenance Guide: Brake Fluid Exchange, AT Fluid, PS Fluid - none for US?

:
mazda
The manual has no maintenance for:
- Brake Fluid Exchange
- AT Fluid
- PS Fluid

Yet both my AT and PS fluid are blackish at 90k - dealer had to flush the Tranny twice to get the color right!

Do u guys have a recommendation for those three - how often should I do?

Roast me if you want, but out of all the cars I've had over all the decades. I have never changed PS fluid. The last issue I've had with a PS steering pump was a blown hose in a '67 Cougar (pump was fine). Never had a pump fail yet and I keep cars 10 years or more. Current ride is going on 18.

I would do brake fluid every two years, only because it sucks moisture out of the air, which cause the temperature sensitivity to go out of whack.

AT fluid should be a 50-60k miles change, depending on use. If you tow anything, or drive a lot of city traffic, I wouldn't go longer than 50k.

They are "life time" fluids. So for the life of the tranny you don't needs to change fluid.
The life of the tranny might be short because you did not change fluid, but the fluid will last the life time of the tranny. (loser)
