Transmission over temp warning comes on when I'm at the track. It takes about 10 minutes of hard use for it to come on. Granted it's Florida and it's been 90 plus degrees. I've been trying to find a system schematic to think of what might be going on. Anyone have any knowledge of the 2007 Z06 tranny system? Does it have a thermostat? An electrical or mechanical pump? Does it always send fluid through the cooler? Etc etc.....Thx!
