ENGINE temp gauge dies and tow haul flashes
I've read several threads about the tranny temp gauge either pegging hot or bottoming out to cold and the tow haul light flashing w/ check gauges popping on and the universal consensus seems to be the tranny temp sensor.
Today I developed a similar problem on the ride home after changing the A/C evaporator core on my 04 F250. However, my tranny temp gauge remained even. It was my engine temp gauge that bottomed out. Same check gauges light, same hard shift that I've read about here, but the engine gauge. Trouble is, in a 4 mile stretch of road, it happened 3 times. The gauge would peg, the light would flash and CG light came on then a minute later, everything went back to normal. A mile or so later, it happens again.
Is it possible that I bumped some wiring connection loose when I was fooling around the evaporator core housing?
