99 PSD Tranny Chatters In Rev and Fwd

[1997 Z71]

Hopefully someone can help me with this. I have a 99 F250 Superduty 7.3. Yesterday I drove about 20 miles into town. The truck ran fine. Coming home pulled up to a light and the truck wanted to take off trying to overcome the brakes. When the light turned green I hit the throttle and it went nowhere. Towed it home. Started it up and when I put it in either Reverse of Drive it chatters terribly, dying the first couple of times. It seems like the torque converter is engaging at idle. The truck has 140,000 miles on it and the tranny has not been serviced like it should of.

Any help would be great.

Just pulled the pan and there are chunks of metal in the pan. They appear to be non metallic. These are not the normal carbon looking filings found around the magnet. They are shiny and quite large. Is this tranny totalled or is there any hope?

Probably aluminum and from the pump. When the pump gets worn, crossleaks in the worm tracks try to apply the tcc clutch at idle. Quite common actually. Unfortunantly and overhaul is on the horison. Preston
