Thanks guys! This gives me a clear (and logical) direction to move in.
Old fluid is getting a better look tonight when I empty the drain pan, but at a glance when I drained it things seemed to be normal but "old", just a dirty dark red.
I'll report back once getting into it Friday!
Special shout out to you
