Decided to do a drain and fill on my 08 runner and my 08 Camry. Here's a sampling of the WS fluid at different stages. Pinkish red (lower left spot) is brand new from the bottle. Slight brown (bigger puddle upper right of photo) is from my 4R at 40,8** miles. Darkest spot (upper left spot in photo) is from the Camry at 80,000 miles.
ALSO- for anyone who says the Scangauge cannot read trans temp, I have a little proof to settle the debate. I used a jumper to put the truck in check mode, then swapped in the SG to see if the temps were right when the a/t temp light on the dash illuminated. Well here's my results. I never took it past 120 because I still had to crawl under the truck and top off the fluid.
