Tow haul light flashes

[1tonpower]

Other then the light flashing the trans is mint. As long as to haul isn't on the trans works as it should. The first ford gerage he had look AR it says the trans is wasted. This doesn't seem right because there are no other symptoms.. Any ideas... There are codes but I don't know them right now

after doing som reading i have found a few cases of the same..this is my buddies truck. the problem started for him after the alternator was replace and both batteries...he was coming home from PA when it the alt crapped out on him. he pushed it untill the truck shut off from low voltage, he put two new batteries in it thinking that was all it needed. he ran those to down also before calling my from Albany NY for a tow home...

any ways im thinking that this is related do to low voltage makes higher amps though solenoids. now the only problem is witch one is it and could anything else be affected

I read somewhere that a flashing Tow/Haul indicator light could be a sign of very high trans fluid temps.
