How often?
And how do I actually do it...?

Looks like the break booster is using the same hydraulic system... and you can actually drain the oil by pulling the hose off at the little oilcooler... or is there another, "official\" way of changing the fluid?

 

I just take a turkey baster and suck the majority of it out every 20K miles or so. Then add back fresh ATF +4.

I drop the lines...I find it gets the most out.

Turkey Baster works fine but don't tell the wife

 

I suctioned mine out a few weeks ago with something similar to a baster. You can't get it all out this way, but I did it a second time a few days ago, essentially replacing it all, for the most part, kinda like doing the tranny.
