I changed my tranny fluid on my 06 2.3 auto a few months back @ about 20k. Replaced it with Mobil 1. My fluid was a dark brown to almost black color it,did not smell burnt though. I have not had any problems with my transmission. Was this a problem, or normal for the Mazda Fluid? The Mobil 1 has remained a nice bright red since the change(been 5k). For those of you that have done your own change, what has been your experience? If you could, post mileage at change.
Thanks..

I did a partial flush (double 3qt flush) at like 17-20k miles, then I did a full 9qt flush all at once using transmission pump at like 23k miles.

Here's my fluid just before I did my full 9qt flush:

Then I was wondering if heat was a cause of this color change due to the small water type ATX fluid cooler, so I added an auxillary cooler. I'll keep track of my fluid every 3k miles or so and see if the cooler keeps mine looking bright red.

yeah... it'd be funny if my fluid turns that color again after 10k miles...

heh

Haha, I was staring at that second to last pic of HouRman's for about 30 seconds wondering how the hell he got the fluid to bend like that as it was draining.. then I realised it was a tube.
