TORQUE CONVERTOR

[20racer]

I have a 2000 f350 and have had trouble with the torque convertor cycling when pulling a load. It does not matter if it's in overdrive or not, I have had it to two tranny shops and they say it's something else causing the tranny to do it. Also it will only do it for maybe five miles then quit, if you stop turn key off and go again it will start all over. I have replaced numerous electronic parts on the motor side with no luck, any suggestions?

Turn's out it was the torque convertor, trans shop said it was the first one he has seen do that, and with the shaving's that went through the tranny it needs a rebuild. Not a good deal since I was trying to figure it out on the engine side and spent a good share of money on various electronic parts.
