Wife called me and said transmission temp light is coming on. After scolding her for driving it back home, I took it out when I got home. Transmission temp is cool, guage reads 130-150, intermittently the transmission dash light and od light blinks and dings. Did it about 4 time within a 2 mile drive. Fluid looks and smells good. 2006 5. 9 Auto. Any help is greatly appreciated. Is this something that should show more info with an ODB scan?
