Amazing overheating problem...desperate

We shall see he says, with bated breath, fear still flashing in his eyes.....I did ALL the work myself and at 76 years old it was still interesting and a type of fun we all know. Now, if I could just find someone to do my auto transmission A727 I believe, or swap it out for a good one. The truck has lasted 300,000 miles and should be good for another 150,000...everything works fine, no major dents just farm yard stuff. I rebuilt everything else then the tranny and radiator traumas began...typical machinery reaction to loving care...laughter...I DO take extraordinarily good care of my vehicles. The yanking towing pulling overloading is what a farm pickup is for...its a TRUCK darn it...laughter

Thanks everyone
