Here's the culprit. This tranny cooler hose overheated, ruptured, and showered ATF all over the exhaust pipe. When new, the braided steel hose is a robust piece. After cooking, it took on the qualities of a wet noodle. "We'd put out the fire, and more tranny fluid would shoot onto the pipe, and the fire would restart," comments Kreg. "If we hadn't been given fire extinguishers by the other teams, we wouldn't have been able to keep pace with the fire, and the truck would have been a total loss."
