Just like ATF, the color change is often significant in showing when reactions with water vapor has taken place. Crystal clear> going to light amber.
After years of experimentation, now I just schedule a FULL system Flush every 12 months, usually to coincide with transmission, coolant, ps, and diff fluid replacements.
Easier to just do it all at once as an addition to one of 90 day oil changes adds 2 hours to the sevice.
