"Dexron HP synthetic fluid in the 1ET35 Transmission appears to be overheated or extremely dark in color"
From this technical GM site: http://gm.oemdtc.com/3244/chevrolet-spark-ev-bev-1et35-transmission-fluid-appears-overheated-or-dark-in-color-2014-2015-chevrolet-spark-ev
Crap, 
skip to the picture at the bottom of the page....
There is such a thing as a $20 Oil Analysis that will scientifically tell you what is going on.
It looks like THE reason for this page is to stifle warranty claims.
Which may be justified, but I plan on running out the clock with this little EV Hot Rod.
I'm going to be changing the ATF sometime this summer (@ ~ 35-40 k miles, not the recommended 97 k.)
I'll be doing it the low-tech way by draining and refilling with the exact same amount that came out.
I'll be using the recommended Dexron HP. I found it for ~$14 qt. (How much do I need?)
And I'll be getting an oil analysis sample kit from the local CAT (heavy equipment) service center. It's a small sample bottle and a post-paid padded envelope. The results are emailed. I'll post them here.
