guys, I'm getting my trans cooler installed tomorrow, and the directions say to drain the stock fluid, and to run redline high temp atf, on the comptech website. I have tried D4 redline atf, on my 2003 accord, and it thinned out within a few months. The manual also states that if you use a dexron 3 fluid, you should change it as soon as possible. Which would you guys use and why? I'm not sure of what the differences between the D4, and high temp redline fluid are, but I'm not sure the high temp won't thin out like the D4.
