I am not sure what all your builder did when he fixed the relief valve in the pump, but if you had the motor running with no fluid it wouldn't take long at all to toast those clutches and Band. Did he go in deeper in the trans when he pulled the pump? I would almost think there had to be a little damage to them from running it dry.. Just an idea.
