I have a f-250 diesel 4x4 auto. trans. My check engine light came on, and then my tow/haul light started flashing. Idrove straight to my local ford dealer to get it checked out. they replaced the ICP sensor and hardware. theysaid that was the problem with the engine light, but I needed to replace the transmission. They gave me a quote of $3,700. I have never had any problems with the tranny, Itow a 38 ft. 5th wheel, and it preforms fine every time. And when I left the dealership the light was not flashing. Has anybody had a problem with the tow/haul light flashing?
