In particular, a transmission sensor failed and allowed a transmission fluid to wick its way through the wire harness and into the computer for the truck. In this case, this caused the truck's starter to engage when the lights for the vehicle were turned on, regardless of whether or not the truck was already running. Additionally, the truck would not stop running, even when the key was disengaged from the ignition. …”
